Bring your OpenAPI spec or API contract.
The fastest way to expose existing APIs as secure Model Context Protocol (MCP) servers.

Separate systems
0mcp handles the platform so your team can focus on your product.
The short path
0mcp turns your API into a hosted MCP endpoint that AI agents can call.
Bring your OpenAPI spec or API contract.
Choose tools, set permissions, and validate.
Get a hosted MCP endpoint ready for AI agents.
That's it.
Just your API, ready for agents.
Core capabilities

Generate AI-ready tools directly from your existing API specification.

Verify every tool with live requests before making it available to AI clients.

Keep users, permissions, and security exactly where they belong in your existing backend.

Create separate environments for customers, partners, internal teams, or different products.

Monitor health, latency, failures, and usage with complete operational visibility.

Deploy API changes and new tools without disrupting connected AI applications.
0mcp stores API specifications, configuration, account data, and operational metadata—not upstream credentials or proxied request and response bodies.
Request path
An agent calls the MCP tool your user allowed.
Request and response bodies and upstream credentials are relayed without being persisted. Operational metadata is retained for reliability.
Your infrastructure handles auth, logic, and data - 0mcp never becomes the source of record.
We keep status codes, latency, and error rates so your team can monitor production health.

FAQ
0mcp is a managed platform that transforms an existing OpenAPI specification into a hosted MCP server.
Your APIs become accessible to AI clients without building MCP infrastructure yourself.
The Model Context Protocol (MCP) is an open standard that enables AI applications to securely discover and interact with external:
Compatible clients include Claude, ChatGPT, Cursor, VS Code, and other MCP-compatible applications.
No. Your existing backend and business logic remain unchanged.
Any client that supports the Model Context Protocol can connect to your MCP server, including:
No. Your APIs remain the source of truth.
0mcp forwards requests securely to your backend and does not store API request or response payloads.
Only operational metadata, such as request status, latency, and errors, is collected for monitoring and reliability.
Yes. 0mcp works with your existing authentication and authorization model.
Requests are securely forwarded to your backend, allowing you to continue using your current security mechanisms.
Yes. You choose exactly which API endpoints become MCP tools.
Internal, administrative, or sensitive endpoints remain private unless you explicitly publish them.
0mcp provides operational features for deployed MCP workloads, including:
Teams should validate their own API behavior, access controls, and service requirements before serving customer traffic.
