PlaceRoot

PlaceRoot runs locally from a Python package published to PyPI: placeroot version 0.10.0. 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 placeroot. It reads the environment variable PLACEROOT_CACHE; set it in the client's configuration for this server.

PlaceRoot runs locally from a Node.js package published to the npm registry: placeroot version 0.10.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y placeroot@0.10.0. It reads the environment variable PLACEROOT_CACHE; set it in the client's configuration for this server.

PlaceRoot runs locally from a Python package published to PyPI: placeroot version 0.10.0. The package starts a local server that speaks MCP over Streamable HTTP; the client then connects to it by URL (the entry names uvx as the runtime). It reads the environment variable PLACEROOT_CACHE; set it in the client's configuration for this server. Required arguments: --http.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "placeroot": {
      "command": "uvx",
      "args": [
        "placeroot"
      ],
      "env": {
        "PLACEROOT_CACHE": "<value>"
      }
    }
  }
}
