mcp-weather
Global weather intelligence MCP server — current conditions, forecasts up to 16 days, historical data, air quality, and marine conditions for any location on Earth. 7 tools powered by Open-Meteo (free, no API key, no…
What it gives an agent
A purpose-built capability behind one MCP connection.
The server owns its domain logic and publishes a tool contract an MCP client can discover. ADK-Rust can load that contract into an agent, normalize each schema for the chosen model provider, and keep the connection lifecycle outside the agent’s business logic.
Architecture
How mcp-weather fits into an agent system.
The model never needs the implementation details or credentials of the system behind the server. It sees reviewed tool definitions. The MCP client handles discovery and calls, while the server keeps ownership of validation, policy, and communication with its domain system.
01
ADK-Rust agent
Chooses a capability from the reviewed tool catalog.
02
MCP client
Discovers schemas, sends calls, and receives typed content.
03
mcp-weather
Validates the request and owns 7 documented tool contracts.
04
Domain system
Keeps the API, data, credentials, and business rules behind the server.
This repository does not currently publish a dedicated architecture SVG. The integration diagram above is generated from its documented transport and server boundary; use the official README for implementation-specific details.
Tool catalog
What can an agent ask mcp-weather to do?
Each tool has a stable name, a human-readable purpose, and a JSON input contract discovered during MCP initialization. Risk classes come from the project’s registry manifest when one is available.
7 named tools
get_current_weatherGet current weather conditions for a location
read onlyget_forecastGet daily weather forecast for up to 16 days
read onlyget_hourly_forecastGet hourly weather forecast for the next 48 hours
read onlyget_historical_weatherGet historical weather data for a date range
read onlyget_air_qualityGet current air quality index and pollutant levels
read onlyget_marine_conditionsGet marine/ocean conditions (waves, currents)
read onlygeocode_locationSearch for a location by name and get coordinates

Understand the effect of every tool.
A server connection inherits the authority of its credentials and deployment environment. The declarations below come from this project’s README and MCP registry manifest; your application still decides which tools an agent receives and where approval is required.
7 read only
- The registry manifest declares read only tool risk classes.
MCP surface
What the current documentation declares.
MCP can carry tools, resources, prompts, structured results, progress, cancellation, and long-running work. This record highlights the modern protocol features explicitly mentioned by this repository.
The current README concentrates on its tool surface. Check the source and release notes before relying on optional MCP capabilities beyond tool discovery and invocation.

Install and connect
Follow the project’s documented starting point.
Install the server in the environment that owns its credentials and domain access. Add it to your MCP host, verify the discovered tools, and narrow the toolset before giving it to a production agent.
Install
cargo install mcp-weatherMCP client configuration
{
"mcpServers": {
"weather": {
"command": "mcp-weather"
}
}
}Commands and configuration are extracted from the public README. Confirm prerequisites, environment variables, and release-specific options in the official documentation before deployment.
