Extending Copilot Edits with tools

[ArtemGovorov]

We are working on chat participant for Copilot Chat for our extensions (Wallaby/Quokka/Ninja), and also register some tools (vscode.LanguageModelTool).

In addition to Copilot Chat, the registered tools may significantly benefit the user in Copilot Edits (in edit or agent), if LLM knows about them and decides to call them.

Right now, looks like chat participants can not be referenced from Copilot Edits. The transition from Chat to Edits via the chat button also doesn't seem to work.

Is there any way or plan to make Copilot Edits aware of registered chat tools (vscode.LanguageModelTool)?

Looks like Cursor, Cline, Windsurf have adopted Model Context Protocol that is supposed to make chats/edits aware of user added tools/tool endpoints:

• https://docs.cursor.com/context/model-context-protocol
• https://docs.codeium.com/windsurf/mcp#mcp-integration
• https://docs.cline.bot/mcp-servers/mcp

Is MCP support on the roadmap for Copilot? If not, is it possible to share the plans on Copilot Edits extensibility via LLM tools?

MCP is supported in Agent mode now. But it seems my chat participant is still in Chat mode only. How can I make my chat participant able to call MCP tools?
