Tools & capabilities
Dark Memory MCP tools 57
dark_memory_project_createCreate a new project (INV-7 tenant primitive). Idempotent on project_id — re-creating an existing project returns the existing row. The 'default' project is seeded on Open and cannot be re-created (returns ErrAlreadyExists).dark_memory_session_startStart an operational session. Returns the session_id. Use session_close to terminate.dark_memory_session_resumeResume an existing session by session_id. Validates the session exists, sets the active project to match, and returns the session row.dark_memory_session_statusReturn the current state of a session (id, operator, project, status, timestamps). Read-only. Includes closing_soon + seconds_until_close so harnesses can warn before the sweeper closes an idle session.dark_memory_session_closeClose the active session. Returns the write/run/item summary.dark_memory_session_heartbeatRefresh a session's last_heartbeat_at so the sweeper does not auto-close it. Call every ~30s during long reasoning pauses or read-only stretches (>60m between writes would otherwise demote the session to closed_aborted). Returns the new last_heartbeat_at.dark_memory_session_recoverDetect the most-recent closed_aborted session for an operator within a lookback window (INV-8). Read-only: never creates a session. Returns the candidate + requires_consent=true when found, so the caller can decide to follow up with session_resurrect.dark_memory_session_resurrectResurrect a closed_aborted session (INV-8): creates a new session inheriting the original's constitution binding + active mods. The original stays untouched. Use session_recover first to discover the candidate. Returns the new session_id + inheritance audit.dark_memory_research_topicRun a research query against the registered ResearchBackend set. Returns deduplicated, confidence-ranked items.dark_memory_research_recallRecall previously stored research items by query, with a token budget. Runs the Atlan 5-bucket economy pipeline.dark_memory_research_resume_threadContinue a multi-turn research thread by re-running ResearchTopic with the same thread_id.dark_memory_agent_bootstrapReturn the markdown content of a dark-agent self-bootstrap resource by surface+target. Surfaces: system_prompt | compatibility_matrix | install_guide (requires target) | companion (requires target) | all. The resource URIs are also exposed via resources/read for harnesses that prefer the standard MCP path.- +45 more on the listing page
