Fireweed MCP Server

Agent memory where every fact carries a receipt. That last one is the artifact behind "delete me from your agent's memory - and prove it.". It runs locally over stdio via the published package.

People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add starksood-fireweed-mcp -- uvx fireweed-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "starksood-fireweed-mcp": {
      "command": "uvx",
      "args": [
        "fireweed-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-08-24 - young repo, little track record yet

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package fireweed-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.Starksood is GitHub-verified and matches the repo owner
