φρήν + νοῦς — Gives your Claude agent long-term, cognitive memory backed by the Frinus platform.
frinus-mcp is an MCP project maintained in the frinus-ai/frinus-mcp repository. The maintainer describes its purpose as “φρήν + νοῦς — Gives your Claude agent long-term, cognitive memory backed by the Frinus platform”. Read the project documentation for the complete scope.
The documented npm package is frinus-mcp. The configuration below comes from the maintainer’s example; adapt its paths and account values to your environment.
The example declares FRINUS_API_KEY. Secret-looking values have been replaced with placeholders. Required and optional labels are shown only when the documentation states them.

| Tool | What it does |
|---|---|
| memory_store | Create a memory. agent_id, content required. memory_type ∈ {episodic, semantic, procedural}. scope ∈ {user, agent, universe, organization}. importance 0–1. |
| memory_search | Semantic similarity search. Filters: agent_id, memory_types, limit. |
| memory_get | Fetch a memory by memory_id (full content, metadata, relevance). |
| memory_list | List memories for an agent_id with optional type filter. |
| memory_delete | Permanently delete a memory by memory_id. |
| memory_reinforce | Boost relevance of a useful memory (memory_id, boost 0–1, default 0.1). |
| memory_weaken | Penalise an outdated memory (memory_id, penalty 0–1, default 0.2). |
| working_memory_get | Load current state for a context. Always call at task start. |
| working_memory_add | Persist current state. Context formats: agent:{uuid}, universe:{uuid}, organization:{uuid}. |
| working_memory_clear | Remove all items for a context. |
| session_start | Begin a session for an agent. Returns session_id. Supports parent_session_id for subagent inheritance. |
| session_end | Terminate a session and finalise its summary. |
| session_context | Combined working + long-term retrieval, enhanced with extracted session topics. |
| session_summary | Generate a structured recap (decisions, learnings, pending items). |
| session_clear | Wipe a session's working state without ending it. |
| stream_capture | Record an input / output / internal note tied to a session. |
| stream_get_session | Replay every captured item for a session_id. |
| stream_get_recent | Recent stream items across sessions (filterable). |
| stream_process | Promote pending items to long-term memory (manual trigger; scheduler also runs every 5 min). |
| memory_get_context | Build a token-bounded context window for a task description. |
| search_with_attention | RAG with task-type-aware weighting. task_type ∈ {implementation, debug, deploy, documentation, review} drives memory_type weights. |
| user_register | Register a user with the memory system (idempotent). |
| user_get_context | Retrieve combined user memories and tenant context. |
| heartbeat_tick | Cheap tick for an agent — drives relevance decay and lightweight consolidation. |
| sleep_run | Trigger a sleep cycle. phases ⊆ {evaluation, forgetting, consolidation, relevance}. Mirrors the scheduler's normal/deep sleeps. |
| consolidation_detect_conflicts | Surface candidate conflicting memories above a similarity threshold. |
| consolidation_resolve_conflict | Keep one memory, supersede the other with a written resolution note. |
| consolidation_detect_redundant | Find near-duplicates ready for merge or removal. |
| hierarchy_consolidate | Roll several related memories into a higher-level summary memory. |
| hierarchy_get_tree | Inspect the consolidation tree for a root memory. |
| agent_create | Create an agent (optionally from a template) scoped to a universe / team. |
| agent_list | List agents in the caller's tenant. Auto-scoped via API key. |
| agent_get | Fetch an agent by agent_id. |
| agent_update | Update persona, team, universe, etc. |
| agent_delete | Delete an agent. |
| agent_invoke | Programmatically invoke an agent with a task. Returns its tool calls and final answer. Used by delegation. |
| universe_create | Create a universe in the caller's org. Slug + name + description. |
| universe_list | List universes for the resolved org. |
| universe_update | Patch a universe (name, description). |
| universe_hierarchy | Walk the full L0 → L3 tree for a universe with status icons. |
| training_teach | Inject a fact or procedure. type ∈ {semantic, procedural}. |
| training_qa | Train with pairs of {question, answer}. |
| training_stats | Coverage statistics across the corpus. |
| training_gaps | Detected gaps in knowledge / weakly-covered topics. |
| training_recent | Most recently ingested memories from training. |
| task_create | Create a task (title, description, optional assigned_agent_id, parent task). |
| task_get | Fetch a task with its full state. |
| task_list | List tasks with filters (status, agent, parent). |
| task_update | Update status, output, or assignment. |
| skill_list | Enumerate available skills in the tenant. |
| skill_assign | Attach a skill to an agent. |
| skill_remove | Detach a skill from an agent. |
| skill_agent_list | List the skills owned by a given agent. |
| credential_store | Store an encrypted credential under a ref (e.g. mysql_x). |
| credential_get | Inspect non-secret metadata only (host/user/db/port + the env vars credential_exec will inject). Never returns the value. |
| credential_exec | Run a command with the credential injected into the child process ENV. Returns only stdout/stderr/exit_code — the secret never reaches the model, screen, or… |
| credential_list | List stored credential refs (no secret data). |
| credential_delete | Delete a stored credential. |
