概要

What is Postmancer?

Postmancer is a standalone MCP server for API testing and management, allowing AI assistants like Claude to make HTTP requests, manage collections of API endpoints, and test API responses through natural language. It offers similar functionality to tools like Postman or Insomnia but is designed specifically for AI assistants.

How to use Postmancer?

Install globally with npm install -g postmancer or run directly with npx postmancer. For Claude Desktop, add a configuration entry with "command": "npx", "args": ["-y", "postmancer"] to the MCP server list. Alternatively, run with Docker using docker run -i --rm --mount type=bind,src=/path/to/collections,dst=/data/collections postmancer.

よくある質問

What is Postmancer used for?

Postmancer allows AI assistants to make HTTP requests, manage API endpoint collections, and test API responses, functioning like a Postman for AI agents.

How do I install Postmancer?

Install globally with `npm install -g postmancer` or run on the fly with `npx postmancer`. It can also be run via Docker.

Where does Postmancer store data?

Collections and environment variables are stored in the path specified by the `COLLECTIONS_PATH` environment variable (default: `~/.postmancer`).

What authentication methods are supported?

Postmancer supports Basic, Bearer, API Key, and OAuth2 authentication methods.

How can I secure sensitive data in Postmancer?

Set `POSTMANCER_ENCRYPTION_KEY` to encrypt credentials and tokens, and `ENCRYPTION_KEY` to encrypt environment variables marked as secrets. If not provided, random or default keys are used, which is less secure.
