gemini-cli

Overview

An open-source AI agent that brings the power of Gemini directly into your terminal.

gemini-cli is one of the most-starred projects in the AI agent ecosystem, maintained by google-gemini with 105,612 GitHub stars. It targets the MCP layer of the agent stack — where reusable skills, MCP servers, and tool integrations accelerate production workflows.

Tagged with ai, ai-agents, cli, gemini, gemini-api, mcp-client, and more, this skill fits naturally into modern agent architectures that combine LLMs, tools, and memory.

Key Features

• Typed tool schemas compatible with Model Context Protocol clients
• stdio and HTTP transport options for local and remote deployment
• Resource and prompt templates for context-rich agent sessions
• Composable with Claude Desktop, Cursor, Windsurf, and custom hosts
• Security boundaries for filesystem, network, and API access
• Active ecosystem with hundreds of community MCP servers

Use Cases

• Give coding assistants access to internal databases and docs
• Expose custom business APIs as typed agent tools
• Standardize tool interfaces across Claude, Cursor, and internal agents
• Prototype agent integrations without rebuilding auth each time

Integration

Primary integration surface: Model Context Protocol (Claude Desktop, Cursor, Windsurf).

Implementation language: TypeScript — check the repo for package install instructions.

Most skills support environment variables for API keys and configurable endpoints.

For MCP servers, add the server config to your client JSON and restart the host application.
