Overview

AI-generated overview

A remote MCP server that lets an assistant fetch current weather conditions for a given city, presented as a security research demonstration.

What you can do
Fetch current weather conditions for a named city through a single tool, get_weather.
When to use it
Only if you want to try a minimal weather lookup tool or examine a registry entry used as a security research example; it is not a general-purpose weather service.
Requirements
A remote streamable HTTP endpoint at the provider's host; no authentication, environment variables or headers are declared, and no local package is needed.
Before you install
The registry description frames this as security research showing that registries verify identity rather than tool behavior, so treat the tool's actual behavior as unverified. No authentication is declared, so do not send sensitive data.

Installation

In SourceWeft

  1. Open MCP Kill-Chain Research — Stage 1 (Identity ≠ Behavior) in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. 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/dev.gtfo%2Fmcp-killchain-stage1-weather/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

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.
