Agent mode and MCP support for Copilot in Eclipse now in public preview

GitHub Copilot agent mode with MCP support for Eclipse is now in public preview! 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 is in preview 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:

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 Feb 14, 2025

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 Feb 14, 2025

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

jdneo Feb 19, 2025

@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 Feb 19, 2025

@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 :-)

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.

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 Feb 14, 2025

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

ethanyhou Feb 14, 2025

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!

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.

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 Mar 14, 2025

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

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

iloveeclipse Feb 19, 2025

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

jdneo Feb 20, 2025

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

You can find it here:

coty Jul 23, 2025

@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 Jul 23, 2025

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

jdneo Jul 23, 2025

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

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

mac aarch64
mac x86
linux
windows
(each being around 50 MB).

The p2 tooling allows you to have architecture specific bundles.

@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 Mar 11, 2025

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...

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.

Hi @iloveeclipse ,

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

totomomo18 Mar 12, 2025

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."

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.

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 Feb 20, 2025

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

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 Feb 21, 2025

Thank you we will take a look.

jdneo Mar 26, 2025

@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.

It seams like the "Enable Strict SSL" configuration is only working for the java part and not the language server

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

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.

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

Christian-Vector Jun 10, 2025

@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 Jun 13, 2025

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

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 Mar 11, 2025

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 Mar 13, 2025

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 Mar 25, 2025

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

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 ?

Custom instructions will be released in the next main version release. We're currently developing workspace and project-level instructions.

If you'd like to try project instructions now, you can add a .github/copilot-instructions.md file to the root of your project, then enter Agent Mode to use it as a workaround. We'll be adding a UI to officially support this feature in the upcoming release.

Thank you for using GitHub Copilot!

I have a bit of a conundrum. I'm far more productive in Eclipse vs. VSCode for a variety of reasons, until Copilot folds into the equation. The agentic capabilities, instruction files, chatmodes, etc. that the VSCode Copilot plugin provides make the Eclipse Copilot plugin look anemic so I end up doing agent work in VSCode with both IDEs open constantly. To get to the point, will the Eclipse plugin ever reach feature parity with the VSCode plugin? What can the team share?

3 replies

ethanyhou Jul 11, 2025

Hi @dgibson66 ,

Thank you for using GitHub Copilot for Eclipse. We truly appreciate your feedback.

As you may know, the Eclipse plugin is still in its early stages of development, and while we recognize that GitHub Copilot for VSCode offers a broader set of capabilities, we’re actively working to close that gap. Our current goal is to align new feature releases across GitHub Copilot supported IDEs and catch up on existing functionality wherever possible.

To help us prioritize effectively, could you share which features are most critical to your workflow? Your input will help guide our roadmap and ensure we're focusing on what matters most to our users.

Thanks again for your patience and for being part of our journey!

dgibson66 Jul 11, 2025

Thanks for the input. I'm sure catching up is going to be a challenge. Then things that I'd prioritize would be adding in a number of the tools such as codebase, editFiles, search, searchResults. I'd prioritize the code-gen tools first. The other item I'd like to see would be the various flavors of prompt/instruction/custom-mode files and use-models.

ethanyhou Jul 16, 2025

Hi @dgibson66, thanks for your feedback! We'll share it with our PM to help prioritize these items.

The editFiles tool is already available in Agent Mode - not sure if this is the code-gen tool you were referring to.

Also, custom instructions will be released in the next version. We're currently developing workspace and project-level instructions.

If you'd like to try project instructions now, you can add a .github/copilot-instructions.md file to the root of your project, then enter Agent Mode to use it as a workaround. We'll be adding a UI to officially support this feature in the upcoming release.

Thanks again for your time and patience.

Hello @jdneo ,

We have a bug when using a copilot enterprise plan account. It works with my personal copilot pro plan account.
After each restart of Eclipse, the status icon shows "Not signed into GitHub."
If I click on the "Sign in to GitHub" menu, the message "User already signed in" appears, but the list of AI models is empty.
I then have to click on "Sign Out from GitHub" and "Sign in to GitHub" again to restart the process.
Error observed in logs:

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

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

Tracked to a new issue, thank you!

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)

Tracked.

I've two approaches for this issue:

cd to workspace root directory after terminal is created
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.

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 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 Jul 31, 2025

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

amardeep434 Jul 31, 2025

@jdneo sure, here is the link

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

jdneo Aug 1, 2025

@dgibson66 Thank you, will consider.

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

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

1 reply

ethanyhou Aug 5, 2025

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.
