Agent mode and MCP support for Copilot in Eclipse now generally available

GitHub Copilot agent mode with MCP support for Eclipse is now generally available! You can enable GitHub Copilot with any GitHub account and experience the autonomous coding experience today.

✨ What's new

Agent mode

With the introduction of agent mode in Eclipse, Copilot functions as an autonomous pair programmer that can perform multi-step coding tasks at your command, such as analyzing your codebase, proposing edits, and executing terminal commands using a defined set of tools. With agent mode, Copilot can even iterate on its own code, detect errors, and fix them automatically.

Each tool in the agent toolkit has specific capabilities that help Copilot complete these tasks. For example, Copilot can search the workspace, read file contents, execute terminal commands, retrieve compile or lint errors from the editor, and apply code changes via a speculative decoder endpoint. The set of available tools continues to grow as we experiment with new ones to further enhance the capabilities of Copilot in agent mode.

Here's what a typical workflow looks like in agent mode after you enter your request:

• Semantic understanding: Copilot interprets your request in Copilot Chat and analyzes the codebase to understand the task's intent and requirements.

• Plan proposal: Copilot leverages your code to build context around the request. Based on its understanding, it breaks the task into smaller steps and formulates a plan.

• Plan execution: Copilot asks for confirmation to take the actions outlined in the previous bullet. Some examples of actions it might take include:

  • Terminal execution: Executing terminal commands for the related tasks such as building the project and installing dependencies. (Demoed by Eclipse IDE).
    

• Task complete: After successfully implementing the changes, Copilot reviews its work, finalizes the task, and provides you with a summary of what changed.

MCP support

Model Context Protocol (MCP) is an open standard that enables AI models to interact with external tools and services through a unified interface. With Copilot supporting MCP in Eclipse, agent mode gets extended capabilities from the tools contributed by MCP servers, so Copilot can assist across more workflows and tasks.

Set up your local MCP servers

You can define your servers in a configuration file (e.g., mcp.json) by doing the following:

• In Eclipse: Click on the GitHub Copilot icon -> Edit Preferences -> find the MCP Servers section

🛠 Try it out

Copilot agent mode and available today to all Eclipse users. You need to update the plugin to the latest version. To access Copilot agent mode for Eclipse, you also need a Copilot license.

On very first time I start typing in the code I always get this error below:

[jdneo]

Hi @iloveeclipse, thank you for the feedback.

Seems that we need to wrap the calling of ContextService.activateContext() to the UI thread.

One question: I tried to reproduce it locally but not success. Is it related with specific eclipse version?

[iloveeclipse]

Hi @jdneo , yes, I was using 4.35 nightly build. You can try with this one, which will be 4.35M3: https://download.eclipse.org/eclipse/downloads/drops4/I20250213-1800/
I can also fix it by myself if you give me access to the code.
See https://accounts.eclipse.org/users/aloskutov#tab-projects

[jdneo]

We've fixed this issue on our end, will let you know if we will release a patch containing the fix. Thank you!

[jdneo]

@iloveeclipse 0.2.0 is released with the fix for this issue. Pls let us know if you can still see the exception. Thank you!

[iloveeclipse]

@jdneo : thanks, so far haven't seen it again with 0.2.0 version. Great!
Next goal: sort out the problem with multipage editors I've reported below :-)

[iloveeclipse]

It seems that every AI interaction / code proposal is logged to the Eclipse Error log as "Info":

Logging is fine, but that pollutes application log with lot of "garbage". Ideally this would be redirected to a dedicated log file and only warnings/errors are printed to the main log file.

[jdneo]

Tracked the issue in our list. Thanks for the suggestion. 👍

[bhavesh4321]

Not working for me :-(

[ethanyhou]

Hi @bhavesh4321 , may I know what issue are you facing?

[hieplq]

I bring my report to here

This message still appears multiple times even after I dismiss it.

comment from ethanyhou
Hi @hieplq ,

Thanks for the feedback. Could you please let me know if the dialogue appears multiple times when Eclipse starts up, or does it occur every time you type a character on the keyboard?

[hieplq]

This message appears on a timer (about every few minutes) and can create duplicates if you don’t dismiss the previous one.

[ethanyhou]

Hi @hieplq,

After investigation, this is a server-side feature despite the IDE environment. You can log out of the plugin and log back in once your quota is refreshed as a workaround. We will also try to improve the user experience in future releases. Thanks for your feedback!

[RyoObayashi]

There are several errors. This is part of them.
What can I do? I'm not familiar with Eclipse, and I apologize if this is a silly question. Thank you.

What I did:
I couldn't install the plugin from the Eclipse Marketplace, so I added the certificates using keytool. I used the following commands:

keytool -import -alias server-cert1 -file "C:\pleiades\2024-12\java\21\lib\security\azuredownloads-g3ahgwb5b8bkbxhd.b01.azurefd.net.crt"
keytool -import -alias server-cert2 -file "C:\pleiades\2024-12\java\21\lib\security\copilot.microsoft.com.crt" -keystore "C:\pleiades\2024-12\java\21\lib\security\cacerts" -storepass changeit

The installation was successful, but the error occurred.

[RyoObayashi]

My issue is not that I cannot download the plugin, but that the downloaded plugin does not work.
Using the linked solution, I was able to download it by loading the certificate myself, but it does not function properly.
I am facing exactly the same problem as N1k145

[RyoObayashi]

My issue was completely resolved by including the following in the eclipse.ini file:
It may also help other users experiencing certificate-related errors.

-Djavax.net.ssl.trustStoreType=WINDOWS-ROOT

[jdneo]

@RyoObayashi Thanks for sharing!

[bohni]

This is just for the java part, I had to set environment variable NODE_TLS_REJECT_UNAUTHORIZED to 0 for the LS to work. See https://github.com/orgs/community/discussions/151288#discussioncomment-12671758

[iloveeclipse]

What is a license restrictions on the bundle? Can it be redistributed with a commercial Eclipse RCP application?

[iloveeclipse]

@ethanyhou : thank you. Can you please give a link to the license file used?

[jdneo]

@iloveeclipse Just got the reply from our legal team that the terms do not restrict redistribution.

You can find it here:

[coty]

@jdneo We have an internal build of our RCP-based application with the Copilot plugin bundled. It works quite well, and I think our customers who use Copilot would find it very useful. Is there any way for us to connect with your legal team for confirmation before we decide to actually ship?

[jdneo]

@hangwan97 could you help connect @coty with the legal team?

[jdneo]

I'm also asking it with legal team, will get back to you.

[kwin]

Please bundle per OS/architecture, currently com.microsoft.copilot.eclipse.core_0.1.0.202502101332.jar is 130 MB, the biggest parts in it being the language server binary which is embedded 4 times

1. mac aarch64
2. mac x86
3. linux
4. windows
   (each being around 50 MB).

The p2 tooling allows you to have architecture specific bundles.

[kwin]

See https://help.eclipse.org/latest/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Ffeature_manifest.html -> plugin->os and plugin->arch

[jdneo]

Thank you @kwin!

This is exactly something we want to do!

[kwin]

When will it be possible to switch the underlying models?

[iloveeclipse]

@ethanyhou : I've tried v0.3.0 now on RHEL Linux 9.2 / Eclipse 4.35 / Java 21, chat view seem mostly work, however the upper half of the chat area doesn't properly repaint, you can see it here where I've resized view few times:

I don't see any errors in the log...

[kwin]

Thanks for the update, I find the UI a bit confusing (at least on Mac OS). It is not clear where the input prompt is at first glance. You should make that more obvious. It doesn't look like any other default input fields...

[ethanyhou]

Hi @kwin, I've notified our designer to redesign the text input area and we will improved the chat view UI in the future releases. Please feel free to let us know if there are any other concerns.

[ethanyhou]

Hi @iloveeclipse ,

It seems like this is an Linux specific issue. We will address it and keep you updated. Thanks for your patience.

cc @jdneo

[totomomo18]

I don't think the Ui being confusing is a only a Linux issue I work with windows and it is the same thing like Kwin said " It is not clear where the input prompt is at first glance. You should make that more obvious. It doesn't look like any other default input fields."

[MARCxGAMBIT]

I am using Eclipse 2024-12 (4.34.0) to develop in an SAP environment. I have installed the Copilot plugin today.

As soon as I open source code (ABAP class, RAP behaviour, Service definition, Table definition) I am getting the following error:

An error has occurred. See error log for more details.
class com.sap.adt.tools.abapsource.ui.sources.editors.AbapSourcePage$OutlineTextOperationTarget cannot be cast to class org.eclipse.jface.text.ITextViewer (com.sap.adt.tools.abapsource.ui.sources.editors.AbapSourcePage$OutlineTextOperationTarget is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @7bbaf968; org.eclipse.jface.text.ITextViewer is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @681c6964)

And when opening CDS views I am getting a similar error:

An error has occurred. See error log for more details.

[DaveBSydney]

Thank you @ethanyhou for this. But can we PLEASE have access to a downloadable archive file for local installation. As mentioned before our network blocks the usual jar file download process. This would be greatly appreciated.

[hangwan97]

@MARCxGAMBIT GitHub Copilot for Eclipse now supports ABAP: https://devblogs.microsoft.com/java/introducing-abap-support-in-github-copilot-for-eclipse/

[ethanyhou]

Hi @DaveBSydney ,

As I replied in your main post, you can download it here.

[DaveBSydney]

Thanks so much @ethanyhou

[MARCxGAMBIT]

@ethanyhou @hangwan97 after upgrading to Copilot 0.4.0 my Eclipse (2024-12) refused to launch. Haven't had the time to reproduce this so I am not sure if it's related to the specific Eclipse version or maybe another plugin I am using. I did a clean install of 2025-03 and now Copilot is working 😍

[iloveeclipse]

We see errors while typing ESC key in our multipage editors, coming from

Note: this also happens if the "Automatically show inline completions" option is off, which is yet another issue (I would assume DiscardSuggestionHandler shouldn't be active in this case).

Yes, and sorry it took time to answer.
Create a new Plug-In project with default wizard, in the opened MANIFEST.MF file go to the MANIFEST.MF tab and hit ESC key.

I've noticed that it is important that the bug appears only if the multipage editor is opened with non-text page first. If the multipage editor opened and the active tab is a text editor, everything is fine. So it seem that the copilot contribution that hooks into the editor open event miss the tab change in multipage editor.

[jdneo]

Is there a listener interface when switching tabs in a multi page editor?

[iloveeclipse]

I guess few possibilities, depending on what your code is doing.
Let assume you have listener that reacts on part opening and does something with the part. It could ask if the part is instanceof MultiPageEditorPart and then add org.eclipse.ui.part.MultiPageEditorPart.addPageChangedListener(IPageChangedListener) to it.

[jdneo]

Thank you we will take a look.

[jdneo]

@iloveeclipse Seems that it's more complicated than I think. I can reproduce it via a markdown file: Opening a .md file will first display the render result in editor, then switch the tab to source, press ESC, I can see the same error.

But the thing is that, it's not a MultiPageEditorPart. It's org.eclipse.mylyn.internal.wikitext.ui.editor.MarkupEditor. But I don't want to fix it case by case. I'm trying to find if there is a general way to fix it.

@l3ender What error did you see?

[l3ender]

@jdneo - thanks for responding! Here's what I see in Eclipse's problem log:

[Error]	[ghostText] Error on ghost text request: FetchError: The pending stream has been canceled (caused by: self-signed certificate in certificate chain)

}

I face this when Copilot tries to do completions, but I have already disabled strict SSL in the Github Copilot configuration so would expect this not to cause an error.

[jdneo]

The pending stream has been canceled (caused by: self-signed certificate in certificate chain)

@l3ender Could you please try setting the the environment variable NODE_TLS_REJECT_UNAUTHORIZED to 0

[Christian-Vector]

@l3ender To trust the cert you can set the environment variable: NODE_EXTRA_CA_CERTS to the path of your cert.
For me this works perfectly behind corporate proxy.

[l3ender]

I think the bug is that the UI option for controlling SSL settings should apply without needing to set other environment variables!

[totomomo18]

It is great the Github Copilot decided to officially support Eclipse. I have tried it on my Sts and the completions of code works fast
but why not Chat option ? Please keep working on it give it a Chat , A multi model select, The ability to create new file not just copy code in the editor and maybe someday to ability to have add/edit multiple files in a single prompt in the chat

[totomomo18]

Awesome It looks good thank you. but why don't I see Claude Sonnet 3.7 as a model to choose. I can understand that I don't see it if I log with an account that is on the free tier but I am logging with a paid user that should have an option of Sonnet 3.7. Copilot4Eclipse who uses your subscription does that. Is this a bug or is this by design ? Also could you tell what could be the next upgrades and when do you except them to come out ? may I suggest you add to option to create a file on the project from the answer on the chat or to apply the change on an existing file. maybe someday you will have multi files edits and creations in Eclipse

[jdneo]

We are trying our best to launch Claude 3.7 ASAP.

Long story short, currently those newest models will launch to different IDEs progressively. Copilot4Eclipse can have it because it mimic itself as a JetBrains IDE during initialization, which is a kind of abuse of the protocol.

BTW, we are also considering some work to make all the models can be launched to all ides at the same time in the future. Which can avoid confusion like this.

[jdneo]

@totomomo18 0.5.0 just released which contains Claude 3.7 & GPT 4.5 in chat

[totomomo18]

Thank you for the update but I don't see the plugin has been updated when I do check for update on eclipse do I need to reinstall it or is there a different update site link ? how do I get the update ? Also I need to know if I use the free tier can I use this plugin at work to develop commercial apps/websites or do my company need to buy a company license ?

[jdneo]

Thank you for the update but I don't see the plugin has been updated when I do check for update on eclipse do I need to reinstall it or is there a different update site link ? how do I get the update ?

Have you tried to search the plugin and click update?

Also I need to know if I use the free tier can I use this plugin at work to develop commercial apps/websites or do my company need to buy a company license
You can find the term in the properties page of the plugin:

[kwin]

Any plans to publically expose the sources on GitHub? Usually Eclipse plugins work best as open source…

[nickzhums]

Hi @kwin , thanks for your suggestion! At this moment, we are more focused on improving this product and making the experience as smooth as possible for the users. We will keep the community updated if we explore this option in the future.

[saltielv]

Is there an update for the chat history retention feature? It would be very useful to be able to revisit past discussions.

[jdneo]

Is there an icon here?

[saltielv]

I just went to double check to see if it was a dark theme thing but there is no icon, just the space where it's supposed to go.

[jdneo]

Wired, this is what it should look like:

What is your eclipse and egit version?

Is there any thing in the overflow (...) menu?

[saltielv]

There is nothing else on that menu.

• Eclipse Version: 2025-06 (4.36.0), Build id: 20250605-1316

• Eclipse EGit (Git integration for Eclipse) 7.3.0.202506031305-r org.eclipse.egit

[jdneo]

Wired, I have the same eclipse version + same egit version, and I can see the icon. What if you change a workspace?

[DaveBSydney]

@jdneo - sorry to bug again but has there been any movement on getting SAP ABAP to work with Agent mode?

[dgibson66]

First gripe with 0.9.0 - stop popping up the Quick Start popup every time I start Eclipse. Add a "Don't show this next time" button.

[dgibson66]

I'm not seeing anything other than unhandled event loop exceptions from SWT which I think are unrelated. One thing I see in my preferences:

\!/=
\\\!/=
\\\\\\\!/=
\\\\\\\\\\\\\\\!/=

but I don't know how recent those are.

[ethanyhou]

Hi @dgibson66 ,

Could you please check the file com.microsoft.copilot.eclipse.ui under your workspace? Like: <Your workspace>\.metadata\.plugins\org.eclipse.core.runtime\.settings\com.microsoft.copilot.eclipse.ui.
Then add a new line to the file: quickStartVersion=1 too see if can fix the problem?

[dgibson66]

That fixed it.

[dgibson66]

[iloveeclipse]

This is fixed in today nightly build.

[vogella]

I love the "What is new page" of Copilot which opens in an editor. A long time ago the platform team was discussing to migrate the "Welcome Screen" to such an approach but we never found the time to do this.

[jdneo]

Thank you for the feedback. We hope to leverage this approach to better exposing our new features. And also considering to using gif/video to make it more intuitive in future releases.

[dgibson66]

We've been seeing this unprintable character since we moved to 0.9.0. We're running 2024-12 on RHEL8.

[jdneo]

@dgibson66 I think it should not be a easy one. Need to invistigate.

[tobiasmelcher]

problem should be solved with eclipse-platform/eclipse.platform.ui#3165 - could anyone help testing the fix?

[dgibson66]

How do I pull it in? I'm currently running on 2024-12.

[tobiasmelcher]

The pull request is merged and now available in the nightly eclipse build which can be downloaded via https://download.eclipse.org/eclipse/downloads/ . Could you please download the latest integration build I20250819-1800, install the copilot plugin and verify that the unprintable characters are no longer visible in the ghost text? Thanks a lot for your help.

[dgibson66]

Looks good. Thank you.

This happens with Eclipse 2025-06 and Copilot 0.9.0 on MacOS.

[kwin]

Unfortunately I cannot reliably reproduce. Hopefully the stacktrace above is enough for you to investigate.

[jdneo]

Tracked to a new issue, thank you!

[kwin]

When agent is executing a command in the terminal (like switch git branch to main) it opens the terminal in an unexpected directory: /Users/.../Applications/Eclipse/eclipse-2025-06/Eclipse.app/Contents/MacOS (i.e. the directory of Eclipse itself instead of the current workspace root directory). As that is kind of unexpected would be good if all terminal based operations triggered by the Copilot agent would be based in the workspace directory (unless otherwise instructed)

[jdneo]

Tracked.

I've two approaches for this issue:

1. cd to workspace root directory after terminal is created
2. check if we can adjust context/prompt to let agent cd to the proper directory. Because the working project location may be different from the workspace root path.

[DaveBSydney]

Access lost to releases.
Hi all. I'm getting the dreaded 404 for https://github.com/microsoft/GitHub-Copilot-for-Eclipse/releases which I accessed just last week. I don't think I did anything to cause this on my end.
Any suggestions?

[amardeep434]

@amardeep434 Added. May I ask why you want to use old version, not the latest?

Thank you. My plugin got updated yesterday to 0.9.3 and since then it is freezing my eclipse. I did open a separate discussion under bugs for this. The same freezing issue was noticed with a few of my other colleagues. Not sure how to capture logs for the same.

Im using eclipse 2025-06 and my colleagues are using 2024-09.

[jdneo]

@amardeep434 Could you provide link to that bug? Let's follow-up there.

[amardeep434]

@jdneo sure, here is the link

[dgibson66]

Please make older versions available on the update site so that we can install them if necessary?

[jdneo]

@dgibson66 Thank you, will consider.

[vogella]

The "Add Folder to Chat" feature from VScode would be also very helpful in Eclipse. Even more useful than the suggested DnD for file.

[jdneo]

Tracked, thank you!

[ethanyhou]

Hi @vogella ,

Thank you for your patience. Add Folder to Chat is now supported. To start using it, please update the plugin to version 0.10.0 :)

[vogella]

Thanks a bunch @ethanyhou

[jdneo]

@vogella Adding folder/file via context menu is support, you can see it if you build the project by your own.

(We haven't release it to the nightly build because we need the key from Eclipse Foundation to sign the plugin, but it's not provisioned yet.)

[DaveBSydney]

Asking again (no response 3 weeks ago).
Is there an update on SAP ABAP in Agent mode?

[ethanyhou]

Hi @DaveBSydney ,

Thank you for your inquiry. ABAP's file system differs significantly, which poses technical challenges when interacting it with GitHub Copilot. We’re actively exploring alternative solutions and will keep you updated as we make progress.

Please stay tuned.

[l3ender]

Is there a changelog or release notes available for Github Copilot for Eclipse? Apart from watching this thread, we'd like to know when new releases ship and what they contain. Thanks!

[jdneo]

You can:

1. click 'Help' > 'Welcome'
2. Select What's New

3. Find the GitHub Copilot entry

[l3ender]

@jdneo - thanks for the response!

Finding "what's new" through the app is helpful, but I'm looking for a way to track releases without needing to do updates. Is there a Github repo that publishes releases (or a changelog) that can be subscribed to for getting updates?

We'd like to know when releases occur so that we can evaluate the changes and inform users to update.

Thanks!

[jdneo]

We are just open sourced the code at https://github.com/eclipse-copilot/eclipse-copilot.

So you can see the changelog there.

[dgibson66]

Running 0.10 in Agent mode with Sonnet 4. It got to Editing <file> and popped up a diff window asking Keep/Undo but didn't actually change anything in the file. Are there logs we can capture to better document issues?

[dgibson66]

I think the flow was that I had a diff open on the file prior to the Agent edits, but I've tried to reproduce it without success. It's also possible that Sonnet thought for a while and then didn't actually change anything. I don't see that as likely.

[jdneo]

@ethanyhou Please check if you can reproduce the issue, thank you.

[dgibson66]

I know what this is. We use Perforce and the P4 extension for revision control. If the file is not marked for edit, it is read-only in the filesystem. Eclipse will automatically mark it for edit and make it writeable if you try to modify it in the editor. However, if it's still read-only and Copilot Agent tries to modify it then nothing gets changed and the diff editor shows up with no changes. If I open the file for edit in the editor, then Agent can apply changes to it.

[jdneo]

So, what should be the right behavior for this case?

Keep the file read-only, not edit it? Or change it to editable and change it?

[dgibson66]

I'm doing some investigation and will post when I have more info.

[kenmc411]

I'm having trouble integrating with an internal (network) MCP server and I'm unable to find any debugging options or log details to troubleshoot the problem. No details are in the Eclipse Error Log view and nothing displays in the Progress view. Copilot seems to connect since I can create 403 type error conditions with bad credentials, but good credentials produce no results and copilot just hangs (forever) with responding to any input.

Looking for some kind of option to get a deeper level of info about what is or is not happening between Eclipse and the MCP server. Unfortunately, I don't have access to the MCP server log details either.

Eclipse Platform 4.36.0.v20250528-2229 org.eclipse.platform.feature.group Eclipse.org
GitHub Copilot 0.10.0.202508110512 com.microsoft.copilot.eclipse.feature.feature.group

[jdneo]

Is there anything in the MCP log? It's in the Console View

[kenmc411]

not much unfortunately, but it does show that it found tools.

[jdneo]

How is your mcp server connected, is it using http? Does it requires auth?

[kenmc411]

Yes to both. Actually https and a Bearer token.

[vogella]

To enable people to follow your planned enhancements, it would be nice if you could migrate you backlog to issues https://github.com/eclipse-copilot/eclipse-copilot/issues and maybe also use projects to plan for the next release?

[jdneo]

Yes, we will do the migrations.

[mvreddy49]

Is it possible to restrict the MCP server usage to certain specific ones at Organization level? Like Defining a Whitelist servers?
