01 · Install Anneal Memory

Claude Code

claude mcp add phillipclapham-anneal-memory -- uvx anneal-memory

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "phillipclapham-anneal-memory": {
      "command": "uvx",
      "args": [
        "anneal-memory"
      ]
    }
  }
}

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

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

license MIT - declared in the repository

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

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