Attestor MCP Server

What the code does

We read the source, 20 h ago · rules 3dff92dd89df

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

        proc = subprocess.run(cmd, capture_output=True, text=True, timeout=180)

    path = os.path.join(home, ".claude", "projects", slug, f"{session_id}.jsonl")

        <select class="field" name="status">
          <option value="active" {% if filters.status == 'active' %}selected{% endif %}>active</option>

This one needs environment variables set before it will start: ATTESTOR_PATH (Directory containing attestor's config.toml. Defaults to ~/.attestor.), ATTESTOR_DISABLE_LOCAL_EMBED (Set to 1 to skip the local Ollama embedder probe (e.g., on hosts without Ollama). Defaults to unset (Ollama is the default embedder).), OPENAI_API_KEY (OpenAI API key (used for the OpenAI text-embedding-3-large fallback embedder when Ollama is unavailable).), OPENROUTER_API_KEY (OpenRouter API key (used for the federated LLM extraction / consolidation paths and for the LongMemEval benchmark runner).). The author declared them in the registry entry; get the values from the project itself.
