A curated, community-driven list of awesome Model Context Protocol (MCP) servers, tools, frameworks, clients, and utilities. MCP is an open protocol that enables AI models to securely interact with local and remote resources through standardized server implementations.

BTW, we provide a full list of MCP (Master Control Program) Servers, which is compiled by a web crawler and contains approximately 6000 entries.

Call for translators! We're looking for translators to help translate this spec for everyone!

Read our documentation in the following languages:

MCP is an open protocol that enables AI models to securely interact with local and remote resources through standardized server implementations. This list focuses on production-ready and experimental MCP servers that extend AI capabilities through file access, database connections, API integrations, and other contextual services.

• Model Context Protocol (MCP) Quickstart
• Setup Claude Desktop App to Use a SQLite Database

• r/mcp Reddit
• Discord Server

When running MCP servers without proper sandboxing, they can execute arbitrary code on your system with the same permissions as the host process. This creates significant security risks.

Warning summary:

• System Access: Full access to files, network, and system resources
• Code Execution: Can run commands on your machine
• Prompt Injection: Malicious prompts could trigger unintended server actions
• Data Exposure: Sensitive data may be accessed or leaked

Best practices:

• Use official implementations (marked with ⭐) when available
• Run servers in VMs or isolated containers
• Review code and configuration before installation
• Limit permissions to the minimum required
• Monitor server activity and logs

Many MCP clients and UIs can connect to servers listed here. Examples include (but are not limited to):

• Claude Desktop / Claude clients
• Zed
• Sourcegraph Cody
• Cursor
• Visual Studio Code
• LibreChat
• Various CLI and browser-based clients

(Icons and links for specific clients are commonly shown on the individual server/project pages.)

• many others to simplify server creation, type-safety, and security best practices

• Always run untrusted or community MCP servers in an isolated environment (container or VM) and restrict access to sensitive resources.
• Prefer official vendor-maintained servers (marked with ⭐) for production use.
• Check each server repo for documentation about transports (stdio, SSE, HTTP), authentication, and example clients.
• This ecosystem evolves rapidly — many new servers, clients, and frameworks are added frequently. If you maintain a server, ensure the repo has clear installation and security instructions.
