Search, weather, travel and MCP tools

Web search

Add a key from Tavily’s free plan. Without it, Natro has no web search.

TAVILY_API_KEY=your_key

Weather

No key needed. Set the place Natro should assume:

NATRO_WEATHER_PLACE=Tbilisi

Travel times

A key for the Google Routes API, in the same Google Cloud project. The free monthly allowance covers personal use.

GOOGLE_MAPS_API_KEY=your_key
NATRO_HOME_ADDRESS=Your street, Your city
NATRO_TRAVEL_MODE=drive

MCP tools

Natro starts the servers in agent/config/mcp.json and offers their tools. Each entry takes:

Key	What it does
command and args	A local server, started as a process
url	A remote server
personal	Its results are personal, so they only go to Claude (default true)
confirm_tools	Tools that need your yes first; "*" for all
enabled	false turns it off without deleting it

${NAME} in args, env or url is replaced from .env, so secrets stay out of the file.
