name: mcp-server-manager description: Discover, register, and verify MCP servers. Use when a user asks to connect/add/install/remove an MCP server, or when you need to manage project MCP configuration.

MCP Server Manager

Workflow

1. Discover candidate servers

   • Check project .mcp.json for existing server configs.
   • Check ~/.claude.json for global MCP servers (Claude Code).
   • Scan for MCP-related packages in package.json or Cargo.toml.

2. Choose a registration target

   • Project-local: edit .mcp.json directly.
   • Global (Claude Code): use claude mcp add / claude mcp remove.

3. Register the server

   • stdio server:

     claude mcp add <name> -- <command> <args...>
     

   • stdio with env:

     claude mcp add <name> -e KEY=VALUE -- <command> <args...>
     

   • Or edit .mcp.json directly for project-local config.

4. Verify registration

   • For .mcp.json: read the file and confirm the entry exists.
   • For global: run claude mcp list to verify.

5. Explain reload requirement

   • MCP servers are loaded at session start; ask the user to restart the session.

Notes

• Infer type from config: url key = HTTP, command/args keys = stdio.
• When multiple sources define the same name, confirm which to use.
• For stdio servers using npx, the package downloads when the server first runs.

  "mcpServers": {
    "tauri": {
      "command": "npx",
      "args": ["-y", "@hypothesi/tauri-mcp-server"]
    }
