Show HN: Metorial (YC F25) – Vercel for MCP (github.com)

59 points by tobihrbr ↗ HN
Hey HN! We're Wen and Tobias, and we're building Metorial (https://metorial.com), an integration platform that connects AI agents to external tools and data using MCP.

The Problem: While MCP works great locally (e.g., Cursor or Claude Desktop), server-side deployments are painful. Running MCP servers means managing Docker configs, per-user OAuth flows, scaling concurrent sessions, and building observability from scratch. This infrastructure work turns simple integrations into weeks of setup.

Metorial handles all of this automatically. We maintain an open catalog of ~600 MCP servers (GitHub, Slack, Google Drive, Salesforce, databases, etc.) that you can deploy in three clicks. You can also bring your own MCP server or fork existing ones.

For OAuth, just provide your client ID and secret and we handle the entire flow, including token refresh. Each user then gets an isolated MCP server instance configured with their own OAuth credentials automatically.

What makes us different is that our serverless runtime hibernates idle MCP servers and resumes them with sub-second cold starts while preserving the state and connection. Our custom MCP engine is capable of managing thousands of concurrent connections, giving you a scalable service with per-user isolation. Other alternatives either run shared servers (security issues) or provision separate VMs per user (expensive and slow to scale).

Our Python and TypeScript SDKs let you connect LLMs to MCP tools in a single function call, abstracting away the protocol complexity. But if you want to dig deep, you can just use standard MCP and our REST API (https://metorial.com/api) to connect to our platform.

You can self-host (https://github.com/metorial/metorial) or use the managed version at https://metorial.com.

So far, we see enterprise teams use Metorial to have a central integration hub for tools like Salesforce, while startups use it to cut weeks of infra work on their side when building AI agents with integrations.

We'd love to hear feedback, especially if you've dealt with deploying MCP at scale!

congrats on the launch!

why do I need a specialized platform to deploy MCP instead of just hosting on existing PaaS (Vercel, Railway, Render)?

also if you're not using VMs, how do you isolate per-user servers?

I wrote a book about MCP: https://leanpub.com/practical-mcp

I'm considering adding more chapters to the book: security, easy deployment, etc. So, I may look into your solution. I believe there are other players also, like Klavis AI, FastMCP and some MCP startups that I cannot remember.

Congratz!

Oh my lord, your timing is perfect. I need this so badly right now. Congrats on the launch, and wow, thank you for making your MCP containers available separately!

The distinction between "Vercel for MCP [integrations]" and "Vercel for MCP [servers]" is meaningful — maybe "Zapier for MCP" is a more appropriate "X for Y"?.

Congrats on the launch!

We’ve just begun implementing Composio. Would love to reconsider if you help clarifying the main differences. From my perspective it looks like you have more robustness features to me as a developer and you’re fully open source (not just the client) whereas Composio has more integrations. But would love your input to clarify. Congrats on the launch!

I like the license (FSL) chosen for the project, but it may need some explaining for others. Can you comment on decision for selecting the Functional Source License (Version 1.1, ALv2 Future License), and the intent from the Metorial team with it including any restrictions on potential commercial use of the platform (i.e. free-to-paid without notice)?

For those who aren't aware of what FSL (https://fsl.software/) is: "The Functional Source License (FSL) is a Fair Source license that converts to Apache 2.0 or MIT after two years. It is designed for SaaS companies that value both user freedom and developer sustainability. FSL provides everything a developer needs to use and learn from your software without harmful free-riding."

I think a nod to how auth is handled would be well worth adding to the README.

Knowing it can integrate with API's is great, but knowing how a consumer of MCP interacts with auth, and how you do so with downstream API's would be very welcome.
