Overview

Expert skill for connecting and managing Model Context Protocol (MCP) servers within the Gemini CLI ecosystem.

When to Use This Skill

Keywords: MCP, model context protocol, mcp servers, mcp config, gemini mcp, stdio transport, sse transport, mcp tool permissions, mcp debugging

Use this skill when:

• Adding new MCP servers via settings.json or CLI (gemini mcp add)
• Configuring transports: httpUrl, url (SSE), or command (Stdio)
• Troubleshooting MCP connection states (CONNECTING, DISCONNECTED)
• Managing MCP tool permissions (Trust vs Ask)
• Integrating local scripts as MCP servers

MCP Server Configuration

MCP servers are defined in the mcpServers object in settings.json.

Transport Types

1. Stdio (command): Runs a local executable. Best for local scripts/tools.

   "local-server": { "command": "node", "args": ["server.js"] }
   

2. HTTP (httpUrl): Connects via standard HTTP.

3. SSE (url): Server-Sent Events for streaming updates.

Quick Decision Tree

What do you want to do?

1. Connect a Local Tool -> Query gemini-cli-docs: "configure stdio mcp server"
2. Connect a Remote API -> Query gemini-cli-docs: "configure http mcp server"
3. Trust a Server -> Query gemini-cli-docs: "mcp server trust settings"
4. List Tools -> Query gemini-cli-docs: "list mcp tools command"
5. Debug Connection -> Query gemini-cli-docs: "troubleshoot mcp connection"

Common Commands

• gemini mcp add - Interactive wizard to add a server.
• /mcp - List connected servers and their status.
• gemini --debug - View raw MCP connection logs (essential for troubleshooting connection issues).

Test Scenarios

Scenario 1: Add MCP Server

Query: "How do I add an MCP server to Gemini CLI?" Expected Behavior:

• Skill activates on "MCP" or "mcp servers"
• Delegates to gemini-cli-docs for configuration Success Criteria: User receives mcpServers settings.json structure

Scenario 2: Configure Transport

Query: "What transport should I use for my MCP server?" Expected Behavior:

• Skill activates on "mcp transport"
• Provides comparison of stdio, HTTP, SSE Success Criteria: User receives transport selection guidance

Scenario 3: Debug Connection

Query: "My MCP server isn't connecting to Gemini" Expected Behavior:

• Skill activates on "mcp connection error"
• Provides debugging steps with --debug flag Success Criteria: User receives troubleshooting workflow
