# MCP Servers — Agent Architecture Layer

> Model Context Protocol servers that extend agent capabilities

3 tools mapped to this layer of an AI agent architecture.

This is one layer of an [AI agent architecture](https://www.frameworkr.ai/blog/what-is-an-ai-agent-architecture.md), not a standalone product category. Design the blueprint first, then pick tools.

- [Context7](https://www.frameworkr.ai/tools/context7.md): MCP server that injects up-to-date library documentation into your agent's context
- [Gemini CLI](https://www.frameworkr.ai/tools/gemini-cli.md): An open-source AI agent that brings the power of Gemini directly into your terminal.
- [MCP Filesystem Server](https://www.frameworkr.ai/tools/mcp-filesystem.md): Anthropic's reference MCP server for reading, writing, and navigating local filesystems
