Postman MCP Server (postmanlabs): MCP server

What Postman MCP Server (postmanlabs) does

According to its repository: “Give your AI agents trusted access to the full Postman platform.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Postman MCP Server (postmanlabs) is listed under Developer tools, a category of 475 servers in the directory, where it ranks #86 by stars.

Topics declared by the repository: postman, agent, ai-agents, api-testing, claude, claude-code.

Installing and connecting Postman MCP Server (postmanlabs)

Distribution modes declared in the official MCP registry:

• npm package (Node.js, usually started with npx)
• MCPB bundle (one-click install in Claude Desktop)
• remote server (streamable-http): you connect to it by URL, with nothing to install locally

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript.

The registry lists 5 secret variables to provide (API key, access token). Keep them in the client's environment variables, never in a shared file or a repository.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

Points found for Postman MCP Server (postmanlabs):

• Secrets: the server acts with your credentials. Create a dedicated key with minimum rights and an expiry date.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on June 10, 2025, the postmanlabs/postman-mcp-server repository has 325 stars and 88 forks, with 5 open issues. It has more stars than 84% of the servers in the directory. It received changes this month. Version published in the registry: 2.14.0 (October 16, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
