Metorial: Open Source Integration Gateway for AI Agents
By
Tobias Herber
Toasted just enough. A reliable bake, gently seasoned.
Summary
Metorial is an open-source integration gateway platform designed to solve backend integration challenges for AI agents. Founded by Tobias and Wen (YC F25), the platform addresses issues with managing MCP server infrastructure, OAuth handling, cold starts, and state management for cloud-hosted AI agents. It provides developers with access to 600+ integrations, serverless deployment for custom MCP servers, full observability, one-line OAuth implementation, Python/TypeScript SDKs, and self-hosting options to help developers build and scale AI agents more efficiently.
Key quotes
· 5 pulledWe found that MCP works great for client-side tools like Cursor and Claude Desktop, but integrating MCP servers on the backend for cloud-hosted AI agents is a mess.
Managing infrastructure, handling OAuth, dealing with cold starts, losing state between connections, and getting everything to work reliably.
We built Metorial to fix that.
Connect to 600+ integrations, deploy custom MCP servers to serverless infrastructure, and get full observability out of the box.
Build faster, scale easier.
