Common questions

Is Weather MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.6.1) reached the registry 11 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Weather MCP Server

mcp-name: io.github.isdaniel/mcp_weather_server

A Model Context Protocol (MCP) server that provides weather information using the Open-Meteo API. This server supports multiple transport modes: standard stdio, HTTP Server-Sent Events (SSE), and the new Streamable HTTP protocol for web-based integration.

Features

Weather & Air Quality

Get current weather information with comprehensive metrics:
Temperature, humidity, dew point
Wind speed, direction, and gusts
Precipitation (rain/snow) and probability
Atmospheric pressure and cloud cover
UV index and visibility
"Feels like" temperature
Sunrise and sunset times (local time at the location)
Get weather data for a date range with hourly details and daily sunrise/sunset times
Get air quality information including:
PM2.5 and PM10 particulate matter
Ozone, nitrogen dioxide, carbon monoxide
Sulfur dioxide, ammonia, dust
Aerosol optical depth
Health advisories and recommendations

Time & Timezone

Get current date/time in any timezone
Convert time between timezones
Get timezone information

Transport Modes

Multiple transport modes:
stdio - Standard MCP for desktop clients (Claude Desktop, etc.)
SSE - Server-Sent Events for web applications
streamable-http - Modern MCP Streamable HTTP protocol with stateful/stateless options
RESTful API endpoints via Starlette integration

Installation

Installing via Smithery

To install Weather MCP Server automatically via Smithery:

npx -y @smithery/cli install @isdaniel/mcp_weather_server

Standard Installation (for MCP clients like Claude Desktop)

This package can be installed using pip:

pip install mcp_weather_server

Manual Configuration for MCP Clients

This server is designed to be installed manually by adding its configuration to the cline_mcp_settings.json file.

Add the following entry to the mcpServers object in your cline_mcp_settings.json file:

"mcpServers": { "weather": { "command": "python", "args": [ "-m", "mcp_weather_server" ], "disabled": false, "autoApprove": [] } } }

Save the cline_mcp_settings.json file.

HTTP Server Installation (for web applications)

For HTTP SSE or Streamable HTTP support, you'll need additional dependencies:

pip install mcp_weather_server starlette uvicorn

Server Modes

This MCP server supports stdio, SSE, and streamable-http modes in a single unified server:

Mode Comparison

Feature	stdio	SSE	streamable-http
Use Case	Desktop MCP clients	Web applications (legacy)	Web applications (modern)
Protocol	Standard I/O streams	Server-Sent Events	MCP Streamable HTTP
Session Management	N/A	Stateful	Stateful or Stateless
Endpoints	N/A	`/sse`, `/messages/`	`/mcp` (single)
Best For	Claude Desktop, Cline	Browser-based apps	Modern web apps, APIs
State Options	N/A	Stateful only	Stateful or Stateless

1. Standard MCP Mode (Default)

The standard mode communicates via stdio and is compatible with MCP clients like Claude Desktop.

# Default mode (stdio)

python -m mcp_weather_server

Explicitly specify stdio mode

python -m mcp_weather_server.server --mode stdio

2. HTTP SSE Mode (Web Applications)

The SSE mode runs an HTTP server that provides MCP functionality via Server-Sent Events, making it accessible to web applications.

# Start SSE server on default host/port (0.0.0.0:8080)

python -m mcp_weather_server --mode sse

Specify custom host and port

python -m mcp_weather_server --mode sse --host localhost --port 3000

Enable debug mode

python -m mcp_weather_server --mode sse --debug

SSE Endpoints:

GET /sse - SSE endpoint for MCP communication
POST /messages/ - Message endpoint for sending MCP requests

3. Streamable HTTP Mode (Modern MCP Protocol)

The streamable-http mode implements the new MCP Streamable HTTP protocol with a single /mcp endpoint. This mode supports both stateful (default) and stateless operations.

# Start streamable HTTP server on default host/port (0.0.0.0:8080)

python -m mcp_weather_server --mode streamable-http

Specify custom host and port

python -m mcp_weather_server --mode streamable-http --host localhost --port 3000

Enable stateless mode (creates fresh transport per request, no session tracking)

python -m mcp_weather_server --mode streamable-http --stateless

Enable debug mode

python -m mcp_weather_server --mode streamable-http --debug

Streamable HTTP Features:

Stateful mode (default): Maintains session state across requests using session IDs
Stateless mode: Creates fresh transport per request with no session tracking
Single endpoint: All MCP communication happens through /mcp
Modern protocol: Implements the latest MCP Streamable HTTP specification

Streamable HTTP Endpoint:

POST /mcp - Single endpoint for all MCP communication (initialize, tools/list, tools/call, etc.)

Command Line Options:

--mode {stdio,sse,streamable-http}  Server mode: stdio (default), sse, or streamable-http

--host HOST Host to bind to (HTTP modes only, default: 0.0.0.0) --port PORT Port to listen on (HTTP modes only, default: 8080) --stateless Run in stateless mode (streamable-http only) --debug Enable debug mode

Example SSE Usage:

// Connect to SSE endpoint

const eventSource = new EventSource('http://localhost:8080/sse');

// Send MCP tool request fetch('http://localhost:8080/messages/', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ type: 'tool_call', tool: 'get_weather', arguments: { city: 'Tokyo' } }) });

Example Streamable HTTP Usage:

// Initialize session and call tool using Streamable HTTP protocol

async function callWeatherTool() { const response = await fetch('http://localhost:8080/mcp', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ jsonrpc: '2.0', method: 'tools/call', params: { name: 'get_current_weather', arguments: { city: 'Tokyo' } }, id: 1 }) });

const result = await response.json(); console.log(result); }
