How to connect Ratebook
Ratebook runs locally from a Python package published to PyPI: ratebook-mcp version 0.1.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Python; clients usually start it with uvx (from uv) or after pip install — the usual command is uvx ratebook-mcp.
In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):
{
"mcpServers": {
"ratebook": {
"command": "uvx",
"args": [
"ratebook-mcp"
]
}
}
