Overview

AI-generated overview

Remote MCP server that gives an assistant current weather and 7-day forecasts for any location, paid per call with USDC via x402.

What you can do
  • Retrieve current weather and a 7-day forecast for a location, returning temperature, humidity, wind, precipitation and weather code as JSON.
  • Look up conditions by latitude and longitude, or by city name through geocoding.
When to use it
Useful when an assistant needs weather-aware answers: travel planning, outdoor event scheduling, agriculture or logistics checks, or building weather-dependent workflows.
Requirements
A remote MCP endpoint (SSE transport) at the provider's host; no API key or signup. Calls are paid per request through x402 with USDC on Base L2, so an x402-capable client and a funded wallet are needed.
Before you install
Each weather call costs money ($0.003 per call) in USDC on Base L2, so an agent can spend funds without a signup gate; a wallet and x402 payment handling are required. Requests go to a third-party host, and payment is processed through Coinbase CDP or PayAI facilitators.

Installation

In SourceWeft

  1. Open Weather API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fweather-api/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
