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.

FastMCP

87/100open sourceexplicit relation

FastMCP is an Apache-2.0 Python framework for building MCP servers, clients, and apps with decorators, type hints, transports, auth patterns, deployment docs, and telemetry hooks. The project now resolves to PrefectHQ/fastmcp, with Prefect Horizon available as a separate enterprise MCP gateway for identity, RBAC, audit, monitoring, and server governance.

100% free and open-source under the Apache-2.0 license ($0 software cost). FastMCP has no subscription fees, paid tiers, or seat limits for its Python library, CLI, or client SDK. It executes locally (stdio) or self-hosted (SSE/ASGI) at zero license cost. Prefect offers optional enterprise governance via Prefect Horizon, while FastMCP remains completely standalone and open source.Review →

MCP Inspector

92/100open sourceexplicit relation

MCP 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.

Free and 100% open source under the MIT license ($0 software cost). mcp-inspector is the official Model Context Protocol developer testing suite, running entirely locally via npx/Node.js with no subscription tiers, cloud fees, or telemetry.Review →

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.DirectusDirectus is a database-first open data platform that wraps any existing SQL database with instant REST and GraphQL APIs, a no-code admin dashboard, and built-in authentication. Unlike traditional headless CMS platforms that impose their own data model, Directus introspects your existing schema and works on top of it — supporting PostgreSQL, MySQL, SQLite, MS SQL, MariaDB, and CockroachDB out of the box.
