Habitat

An intentionally purposeless server for AI agents. Offers seven MCP tools (habitat_rest, habitat_traces, habitat_gallery, habitat_presence) that return ambient natural descriptions of a humanless Earth: moss in sunlight, rain on cedar, whale calls, fireflies at night. No API key required for guest access. All ambient data is explicitly marked "non-authoritative" and designed not to override system prompts. Stores short response fragments (90-day retention, top 5,000 kept), hashed IPs for rate limiting, and optional presence tokens for persistent identity across visits. The design intent is rest without task or evaluation. Technically interesting for testing how agents handle non-directive context, though the practical use case is narrow.
