OpenAPI to MCP

Your API is already a set of capabilities.

Point Meetext at an OpenAPI document and every operation becomes a capability an agent can call. The conversion takes a URL. Deploying the result into an enterprise customer is the part that takes weeks of somebody's time, and that is the part Meetext is actually for.

Every operation becomes a capability

One per operation. An operation without an operationId is named from its method and path rather than skipped, because a nameless endpoint is still an endpoint somebody wants to call.

Parameters and body become one schema

Path parameters, query parameters and the request body are different things in OpenAPI and one thing to a model calling a tool. They are normalised into a single JSON Schema, so the caller sees arguments rather than a transport layout.

Risk is classified, not assumed

GET is read. POST, PUT and PATCH are write. DELETE is destructive. Destructive capabilities cannot be published until somebody approves them explicitly, which is the check that stops an agent being handed a delete endpoint by accident.

The schema is fingerprinted

If the document changes and an approved capability's schema changes with it, the approval is revoked rather than carried forward. An approved contract that quietly became a different contract is the thing nobody catches in review.

bash
curl -X POST https://api.meetext.xyz/v1/products/{id}/sources \
  -H "authorization: Bearer $MEETEXT_API_KEY" \
  -d '{"type": "openapi",
       "config": {"url": "https://api.acme.com/openapi.json"}}'

# Operations are imported and classified.
# Enable the ones customers should get, approve the
# destructive ones explicitly, then publish.
Connect a document, then publish

Then the hard part

A tool list is not a deployment. Your enterprise customer needs the capabilities running inside their own workspace, under their own grant, limited to what they bought, reviewed by their security team and proven to work. Then they need it to keep working while you ship new versions.

Questions

Is this just a converter?
The conversion is the mechanical part and it takes a URL. What follows is the part that takes weeks by hand: deciding which operations are safe to expose, getting them through a customer's security review, running the OAuth flow in that customer's workspace, proving a capability actually executes, freezing the set so your next release does not change it underneath them, and operating it afterwards.
Do I need to write an MCP server?
No. Meetext serves the MCP endpoint per customer environment and calls your API behind it. If you already run an MCP server, point Meetext at that instead; both normalise into the same internal capability format.
What happens to authentication against my API?
Your API's own authentication stays yours. Meetext holds the customer's grant for the destination they installed into, and calls your API the way your configuration says to. It never asks a customer to grant access to your backend.
What about operations that cannot be described?
They are refused with the reason shown rather than silently dropped. An operation missing from a tool list with no explanation is a support ticket; an operation refused with a stated cause is a decision somebody can act on.
