mcphub.nvim and CopilotChat.nvim integration

[deathbeam]

So it took me a while to finish the refactor in CopilotChat.nvim required for this but its finally done, so now mcphub.nvim integration is pretty easy and looks like this.

Stuff mostly works now so I feel like sharing this also here might be useful

Thanks @deathbeam for the integration. I will try to add copilotchat as an extension so that users can just enable or disable in the mcphub config. Something like:

  extensions = {
    copilotchat = {
      enabled = true,
      convert_tools_to_functions = true,
      convert_resources_to_functions = true,
      add_mcp_prefix = false,
    },

This way we can auto approve some tools or show confirmation prompt with what's being etc and also user can avoid changing the integration code when something changes.

[deathbeam]

Hmm how would auto approval work here? As how copilotchat tool calling works is that when LLM returns tools, they get appended to next prompt, and the confirmation is user simply either sending the tools or deleting them from the prompt, and user can also see what tools are being called with what paremeters there, example (the parameters are added as virtual lines next to each tool call)

[ravitemer]

Oh in that case, auto_approval isn't necessary. It might come in handy when in some kind of autopilot mode. I have opened #218 PR and for now commented out the auto approval logic.

Native CopilotChat Extension Available

We've added native CopilotChat support to mcphub.nvim that's much cleaner than the manual integration.

Migration Required

If you're using the old manual integration code, please remove it completely and use the new native extension instead.

New Setup

1. Install CopilotChat normally:

{
  "CopilotC-Nvim/CopilotChat.nvim",
  build = "make tiktoken",
  opts = {},
}

2. Enable mcphub CopilotChat extension:

require("mcphub").setup({
  extensions = {
    copilotchat = {
      enabled = true,
      convert_tools_to_functions = true,     -- Convert MCP tools to @functions
      convert_resources_to_functions = true, -- Convert MCP resources to @functions  
      add_mcp_prefix = false,                -- Add "mcp_" prefix to function names
    },
  }
})

What You Get

• All MCP tools become @server_tool functions
• Functions organized by server in CopilotChat UI
• Real-time updates when MCP servers change
• Conflict handling for complex server names
• MCP resources available as functions

Make sure to remove any previous mcphub + CopilotChat integration code before switching to this native extension.
