Postproxy MCP Server

MCP (Model Context Protocol) server for integrating Postproxy API with Claude Code. This server provides tools for publishing posts, checking statuses, and managing social media profiles through Claude Code. Its 34 documented tools cover comments, queues, profiles, message. It is available as a remote MCP endpoint.

Teams that want a hosted social media endpoint instead of running a local process. The project is written in TypeScript.

01 · Install Postproxy

before you install - you'll need

Set POSTPROXY_API_KEY, POSTPROXY_BASE_URL before connecting.

Claude Code

claude mcp add postproxy-postproxy-mcp --transport http https://mcp.postproxy.dev/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "postproxy-postproxy-mcp": {
      "url": "https://mcp.postproxy.dev/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
