GitHub Copilot CLI

GitHub Copilot CLI uses Filestar through the MCP server that comes with the Filestar CLI (filestarcli mcp).

Add it

filestarcli agent install --agent copilot-cli

Or add it by hand to Copilot CLI's MCP file, keeping any servers that are already there:

System File
Windows %USERPROFILE%\.copilot\mcp-config.json
macOS and Linux ~/.copilot/mcp-config.json
{
  "mcpServers": {
    "filestar": {
      "type": "local",
      "command": "filestarcli",
      "args": ["mcp"],
      "tools": ["*"]
    }
  }
}

You can also add it from inside Copilot CLI with /mcp add.

If Copilot CLI cannot start the server, use the full path to the CLI as command, or "command": "npx" with "args": ["-y", "filestar", "mcp"].

Check it

Start a new Copilot CLI session and run /mcp show: filestar should be listed. Then ask:

Remove it
