CopilotChat Integration

Add MCP capabilities to CopilotChat.nvim by adding it as an extension. CopilotChat now has native function-calling support, making it easy to integrate MCP tools and resources.

Features

• Tool Integration: Register MCP tools as CopilotChat functions with proper schemas
• Resource Integration: Register MCP resources as CopilotChat functions for easy access
• Server Groups: Functions are organized by MCP server name for better organization
• Real-time Updates: Automatic updates in CopilotChat when MCP servers change

Setup

Enable CopilotChat Extension

Add CopilotChat as an extension in your MCPHub configuration:

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

Configuration Options

• convert_tools_to_functions: When true, all MCP tools are registered as CopilotChat functions
• convert_resources_to_functions: When true, all MCP resources are registered as CopilotChat functions
• add_mcp_prefix: When true, adds "mcp_" prefix to all function names (e.g., mcp_github__get_issue)

Usage

MCP Tools

When convert_tools_to_functions = true, all MCP tools become available as CopilotChat functions. Functions are automatically organized by server name, making it easy to see all tools from a specific MCP server. Tool names follow the pattern server_name__tool_name:

Examples:

• @neovim__read_file - Read a file using the neovim server
• @github__create_issue - Create a GitHub issue
• @fetch__fetch - Fetch web content

MCP Resources

You can use # to access MCP resources as variables in CopilotChat. In addition, when convert_resources_to_functions = true, all MCP resources will also be available as CopilotChat functions:

Examples:

• #neovim__Buffer - Access current buffer content
• @neovim__Buffer - Get current buffer content (as a function)

Example Workflow

1. Start CopilotChat and type @ to see available functions
2. Select MCP functions from your connected servers
3. Use tools: @github__create_issue Fix the navigation bug
4. Access resources: @neovim__current_buffer Show me the current file content
5. Organize by server: Browse functions grouped by MCP server
