Postmcp CLI
postmcp · MCP server
Postmcp CLI runs an MCP server from an OpenAPI or Swagger specification, given as a URL, local file or preset, so an AI assistant can call a REST API without code being written. Options prune and compact responses, route tools on demand through a tool search, and simulate destructive requests in a dry-run mode. It can also inspect a specification, generate a standalone TypeScript or Python FastMCP server, export client settings and open a visual studio for choosing endpoints.

Why it's useful
You can give an AI assistant access to a REST API from its OpenAPI description without writing a server by hand.
What you could do with it
- Run an MCP server straight from an OpenAPI URL, passing a bearer token or API key for the target API.
- Inspect a specification to see its endpoints, risk tiers and token counts before you expose it.
- Generate a standalone TypeScript or Python FastMCP server project from a specification.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
The Postman for MCP. Turn any OpenAPI spec into a context-optimized MCP server in seconds.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.1.38, the file with digest sha512-qgBLrYBUfelbaM0Vi45IfWJWvryi58oyaFesrfCUTZrVJ2m3+V8qmKIGE7sXdFeAXooPfkMK6VwelFx4hY7hkA==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
The badge, if this is your listing
It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
