Toolsdk Mcp Registry

MCPSDK is a free TypeScript SDK for building agentic AI applications with instant access to a large catalog of Model Context Protocol servers. The site advertises more than 6,000 servers that a developer can connect to with a single line of code, and it also hosts many of them as a service behind a single hub entry point. It targets developers building agents on the OpenAI SDK or the Vercel AI SDK. The home page walks through an example research and outreach agent that searches for news and sends emails on its own. The catalog is browsable by category, including browser automation, databases, code execution, version control and search, and listings are marked as verified where applicable. The roadmap shows the core SDK, server hosting, the hub server and federated search with the official MCP Registry as completed, with OAuth 2.1 authorization, sandboxed execution and a monitoring dashboard in progress, and agent templates, a custom server builder and enterprise features such as SSO and audit logs planned. The free plan costs $0 and includes unlimited access to all MCP servers, the typed TypeScript SDK, integrations with both SDKs and documentation. A paid tier for commercial and high throughput use, with priority support, higher rate limits, advanced analytics and dedicated infrastructure, is listed as coming soon without a price.
