Felt

An MCP server for interacting with Felt maps programmatically.

Prerequisites

• Python 3.14+
• uv
• A Felt API token

Configuration

Set your Felt API token as an environment variable:

export FELT_API_TOKEN=felt_pat_...

Running locally

uv sync
uv run python -m felt_mcp.main

The server uses stdio transport by default, which is the standard for MCP servers launched as subprocesses by an MCP client.

Running with Docker

docker build -t felt-mcp .
docker run -e FELT_API_TOKEN felt-mcp

MCP client configuration

Add this to your MCP client config (e.g. Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "felt": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/felt-mcp", "python", "-m", "felt_mcp.main"],
      "env": {
        "FELT_API_TOKEN": "felt_pat_..."
      }
    }
  }
}

Or with Docker:

{
  "mcpServers": {
    "felt": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "FELT_API_TOKEN", "felt-mcp"],
      "env": {
        "FELT_API_TOKEN": "felt_pat_..."
      }
    }
  }
}
