With nearly 90,000 GitHub stars, this JavaScript-based project provides concrete examples using both TypeScript and Python SDKs, illustrating how to extend LLM capabilities.\n\n## Core MCP Integration and Capabilities\n\nAt its heart, `servers` showcases how LLMs can securely interact with external systems through MCP. The repository categorizes its offerings into two main groups: Reference Servers and Third-Party Servers.\n\n**Reference Servers** are built with the TypeScript MCP SDK or Python MCP SDK and demonstrate a wide range of MCP features. These include:\n\n*   **AWS KB Retrieval:** Accessing knowledge bases via Bedrock Agent Runtime.\n*   **Brave Search:** Performing web and local searches using Brave's Search API.\n*   **EverArt:** Generating AI images with various models.\n*   **Filesystem:** Secure file operations with configurable access controls.\n*   **Git/GitHub/GitLab:** Tools for reading, searching, manipulating Git repositories, managing GitHub repositories, and integrating with the GitLab API.\n*   **Google Drive/Maps:** File access and search for Google Drive, alongside location services and directions for Google Maps.\n*   **Memory:** A knowledge graph-based persistent memory system.\n*   **Databases:** Read-only access and schema inspection for PostgreSQL, SQLite, and Redis.\n*   **Browser Automation:** Utilizing Puppeteer for browser tasks.\n*   **Fetch:** Web content fetching and conversion for efficient LLM usage.\n*   **Time Utilities:** General time-related functions.\n\n**Third-Party Servers** extend this ecosystem, comprising official integrations maintained by companies like 21st.dev, Adfin, AgentQL, and Aiven, which are production-ready. Community-developed servers further diversify the applications, spanning domains like blockchain, e-commerce, and productivity.\n\n## Setting Up and Configuring MCP Servers\n\nGetting an MCP server from this repository up and running is straightforward. TypeScript-based servers can be executed directly using `npx`. For instance, to run the memory server:\n\n`npx -y @modelcontextprotocol/server-memory`\n\nPython-based servers leverage `uvx` or `pip`. After installing `uv` or `pip` as per their respective instructions, you can run a Python server like the Git server:\n\n`uvx mcp-server-git`\n\nAlternatively, using `pip`:\n\n`pip install mcp-server-git; python -m mcp_server_git`\n\nOnce a server is running, you configure it into an MCP client. For clients like Claude Desktop, this involves specifying the command and its arguments within the `mcpServers` configuration. This step effectively wires the LLM client to the capabilities exposed by the running MCP server.\n\n## References\n\n*   [servers on GitHub](https://github.com/modelcontextprotocol/servers)\n*   [Model Context Protocol Documentation](https://modelcontextprotocol.io/introduction)\n*   [servers on model-context-protocol.com](https://model-context-protocol.com/servers/)","keywords":["servers","mcp-server","llm-tool-access","model-context-protocol","ai-integration"],"published_at":"2026-07-13T12:00:35.63+00:00","related_repository":{"slug":"model-context-protocol-mcp-servers","type":"Server","url":"https://model-context-protocol.com/servers/model-context-protocol-mcp-servers"},"source_url":"https://model-context-protocol.com/blog/servers-mcp-server-reference-for-llm-tool-access-and-data-mcp-server-guide"}
