What is the Promptregistry MCP MCP server?

Promptregistry mcp mcp server lets Claude, Cursor and other MCP clients work with Promptregistry MCP directly. A Model Context Protocol server for managing prompts via stdio.

What Promptregistry MCP does

  1. If the environment variable PROMPT_REGISTRY_PROJECT_DIR is set, prompts are stored in that directory. 2. If not set, prompts are stored in ~/.promptregistry/ in your home directory. On first startup, or if prompts are missing, the server will attempt to copy predefined prompts from a local default_prompts_data/ directory (if present) into ~/.promptregistry/.

Tools it exposes

Once connected, the assistant can call this tool directly:

  • Args — * id, content, description (optional), tags (optional), variables (optional), metadata (optional)

Installing the promptregistry mcp mcp server

The server is distributed via npm as @smithery/cli, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

The server reads one environment variable: PROMPT_REGISTRY_PROJECT_DIR. Keep credentials in your client's env block or a secrets manager rather than committing them.

Requirements

  • Node.js: Version 18 or higher. * npm (or yarn). * (Optional) Docker: If you want to run the server in a container.

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Promptregistry MCP sits in that group, and the shape of its toolset — Args — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by stevengonsalvez, written in TypeScript.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the promptregistry mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
