Install guidance

Install in MCP

Connect the bundled MCP server shipped in the repository .mcp.json file.

MCP docs

Clone the repository

Register the server in your MCP client
Claude Code reads a project .mcp.json file and asks you to approve its servers when you open the folder. Other clients keep their own MCP configuration, so copy the server entry from .mcp.json into that client. If this repository configures its server differently, follow the MCP setup the publisher documents.
3
Verify the server
Check the MCP server list in your client. The server declared in .mcp.json should report as connected. In Claude Code, run /mcp to see it.
