hijaz/postmancer

Developer Tools

A MCP server for replacing Rest Clients like Postman/Insomnia, by allowing your LLM to maintain and use api collections.

Direct install

Run the underlying MCP server directly — without Agent-CoreX routing.

npx -y postmancer

Agent-CoreX intelligently routes which tools from hijaz/postmancer your AI agent actually needs per request — reducing token usage and cost.

agent-corex.json

{
  "mcpServers": {
    "postmancer": {
      "command": "npx",
      "args": [
        "-y",
        "postmancer"
      ]
    }
  }
}

Connect in 2 minutes. Only pay for the tools your agent actually uses.

Git repository operations and history inspection

Support for step-by-step reasoning with explicit thought processes

Access GitHub repositories, issues, and pull requests
