MCP Python SDK

85/100open sourceexplicit relation

The official Python SDK for the Model Context Protocol, enabling developers to build MCP servers and clients with asyncio support. Provides type-safe tool definitions, resource management, and all standard MCP transports. The most popular Python package for MCP development with comprehensive documentation.

100% free and open-source under the MIT license ($0 software cost). The official MCP Python SDK has no licensing fees, subscription tiers, or seat limits. It can be self-hosted, embedded, and distributed freely for building local (stdio) and remote (SSE/ASGI) MCP servers and clients.Review →

MCP TypeScript SDK

open sourceexplicit relation

The official TypeScript SDK for the Model Context Protocol, providing everything needed to build MCP servers and clients. Supports stdio, SSE, and Streamable HTTP transports with built-in auth helpers. Works across Node.js, Bun, and Deno runtimes for maximum deployment flexibility.

100% free and open source under the MIT license ($0). The official MCP TypeScript SDK (@modelcontextprotocol/sdk) provides type-safe tools, resources, and stdio/SSE transports for building MCP clients and servers with no licensing fees.

mcp-use

open sourceexplicit relation

mcp-use is an open-source framework that enables any LLM to interact with MCP servers through a unified client interface. It bridges the gap between models that lack native MCP support and the growing ecosystem of MCP tools by providing automatic tool discovery, execution management, and multi-server orchestration. Supports both direct LLM connections and agent-based workflows. Over 9,000 GitHub stars.

100% free and open-source full-stack framework and developer toolkit for the Model Context Protocol ecosystem (MIT License). Includes TypeScript and Python SDKs, an interactive browser-based MCP Inspector for real-time debugging, React-based UI widget rendering for AI clients, and dynamic multi-server connection aggregation at $0 cost.

mcp-go

84/100open sourceexplicit relation

mcp-go is a Go implementation of the Model Context Protocol, providing both server and client SDKs for building MCP integrations in Go. It supports stdio and SSE transports, resource management, tool registration, and prompt templates. Designed for Go developers building MCP servers for DevOps tools, CLI applications, and backend services. Over 8,000 GitHub stars.

100% free and open-source under the MIT license ($0 software cost). Developed by Mark3Labs, mcp-go has no licensing fees, subscription tiers, or seat limits. It can be freely compiled, embedded, and deployed to build high-performance MCP servers and clients.Review →

mcp2cli

open sourceexplicit relation

mcp2cli turns MCP servers, OpenAPI specs, and GraphQL endpoints into standard CLIs at runtime — no codegen, no schema bloat. Tools and arguments load only when requested via --list and --help flags, cutting up to 96–99% of the tokens that native MCP integrations waste on schema preloading. Works with Claude Code, Cursor, Codex, and any agent that can call shell commands, and ships with OAuth, stdio/HTTP/SSE transports, and a bake mode for reusable connections.

100% free and open source under the MIT license ($0 software cost). mcp2cli is an open-source CLI tool that automatically wraps and exposes Model Context Protocol (MCP) servers as interactive command-line utilities with zero licensing fees.

MCP InspectorMCP Inspector is the official interactive developer tool from the Model Context Protocol team for testing, debugging, and validating MCP servers. It provides a visual interface to inspect available tools, test transport configurations, export configs for different clients, and verify protocol compliance during MCP server development.MCP-ScanMCP-Scan is a security tool that scans MCP servers for vulnerabilities including tool poisoning, prompt injection, cross-origin escalation, and rug pull attacks. Acquired by Snyk in 2026, it is the first dedicated security scanner for the MCP ecosystem. It analyzes tool descriptions, permissions, and behavior patterns to detect malicious or compromised MCP servers before they can exploit AI agents.GitHub MCP ServerGitHub MCP Server is the official Model Context Protocol server from GitHub that connects AI assistants to repositories, issues, pull requests, workflows, and code search. It exposes 100+ operations with toolset filtering, permission scoping, and audit logging, available in both remote-hosted and self-hosted Docker deployment modes.MCP RegistryThe official, community-run registry for discovering and publishing Model Context Protocol (MCP) servers — an open index that MCP clients read to find available servers.Context7Context7 is an MCP server developed by Upstash that injects up-to-date, version-specific documentation directly into AI code editors and coding assistants. By typing 'use context7' in prompts, developers get accurate library documentation instead of hallucinated or outdated API references. It pulls from official source documentation and serves it through the Model Context Protocol, solving the common problem of LLMs generating code with incorrect or nonexistent API calls.chrome-devtools-mcpchrome-devtools-mcp is the Chrome DevTools team's official MCP server that lets coding agents control and inspect a live Chrome browser with first-party Chrome DevTools Protocol fidelity. It exposes Network inspection, Performance traces, Lighthouse audits, console output, and structured DOM snapshots as typed MCP tools, so agents can debug real pages and ship reliable web performance investigations without resorting to brittle DOM scraping.Docker MCP GatewayDocker MCP Gateway is Docker's open-source orchestration layer for Model Context Protocol servers. It gives MCP clients one gateway, launches catalog servers in isolated containers on demand, injects credentials, applies runtime restrictions, and routes tool requests. Catalogs and profiles let teams reuse approved server collections across clients, while Docker Desktop can run the gateway automatically with MCP Toolkit enabled.SupermemorySupermemory is a memory and context platform for AI assistants and agents. It ranks #1 on LongMemEval, LoCoMo, and ConvoMem, supports MCP for Claude/Cursor-style clients, provides plugins for developer tools, and combines memory extraction, user profiles, hybrid search, connectors, and RAG in one API.SerenaSerena is a free, open-source coding agent toolkit that provides IDE-like semantic code retrieval and editing capabilities to any LLM via the Model Context Protocol (MCP). Built on Language Server Protocol (LSP) integration, it enables symbol-level navigation, cross-file refactoring, and relational code understanding across Python, TypeScript, Go, Rust, Java, PHP, and more — without requiring file-level reads or text-based search.
