List m3 tool domains (memory, chatlog, files, entity, agent, tasks, conversations, admin) and their tool counts. Call tools_load_domain to expose a domain's full tool surface.

Register a tool domain's full surface for the current MCP session. Use when you need tools beyond the essentials (memory_search, memory_write, memory_get, chatlog_search, chatlog_write, files_search). Valid domains: memory, chatlog, files, entity, agent, tasks, conversations, admin.

Discover m3-memory tool capabilities, parameters, and availability. Allows filtering by a logical domain (memory, chatlog, files, entity, agent, tasks, conversations, admin, diagnostics) or searching by keywords.

List m3 catalog tools (optionally one domain) as structured rows: name, domain, one-line summary, destructive flag, and arg specs (name/type/required). Use this to discover the exact args for any tool before calling it via m3_call — cheaper than a failed call. Read-only catalog metadata; never returns tool output. Domains: memory, chatlog, files, entity, agent, tasks, conversations, admin.

Invoke ANY m3 catalog tool by name without loading its domain — the low-token path to the full tool surface. Single call: pass tool (e.g. 'files_stats') and args (an object). Batch: pass batch, a list of {tool, args} (each isolated — one failure won't abort the rest; capped at 100). Set dry_run to validate args + check the destructive gate WITHOUT executing. Returns JSON. Call m3_index first if you don't know a tool's args. Destructive tools require MCP_PROXY_ALLOW_DESTRUCTIVE=1.

Creates a MemoryItem and optionally embeds it for semantic search. Contradiction detection is automatic — if new content conflicts with an existing memory of the same type/title, the old one is superseded. Use type='auto' to let the LLM decide the best category.

Explicitly supersede an existing memory with a new one. Use this to record an intentional update — 'this fact replaces that specific memory' — when you know the old memory's id. Unlike memory_write's automatic contradiction detection (a cosine + title heuristic that may link the wrong prior memory or none at all), this targets the given old_id deterministically. Non-destructive: the old memory is retained, its validity interval is closed (is_deleted=1, valid_to set), and a 'supersedes' edge is recorded new -> old. The old memory stays retrievable by id and via memory_history, and as_of-filtered search still sees it valid before the supersession point — it is only dropped from default search. Fields you omit (type, title, importance, scope) are inherited from the old memory, so pass only what changed. To hard-delete instead, that is a separate gated tool (memory_delete). old_id MUST be the full UUID — a prefix is rejected (full UUID required for mutation safety; memory_get accepts a prefix, this does not). Note: each supersede creates a NEW successor memory; call it once with the full id, do not chain supersedes.

Search across memory items using semantic similarity or keyword matching. Filter by user_id and scope for isolation.

Retrieves a full MemoryItem; accepts full UUID or 8-char prefix; ambiguous prefixes return an error.

List registered agents, optionally filtered by status and/or role.

List tasks with optional filters. Newest updated first.

Append one chat turn to the chat log DB. Provenance (host_agent, provider, model_id, conversation_id) is required. Writes are async-queued — returns the row id immediately.

Search chat_log rows. FTS5 keyword when query is non-empty; filter-only when empty.

One-call health summary of the chat log subsystem: mode, DB paths, row counts, queue depth, spill files, embed backlog, hook timestamps, redaction state, warnings.

Hybrid FTS5 + vector search over file-ingestion leaves. Default: current versions only. Set include_history=True for time-travel queries. Use corpora for fan-out across multiple corpora.

Return file-level summaries for triage (wiki-index primitive). Cheap-first retrieval -- no leaf content. Use BEFORE files_search to decide which files are worth deep-reading.

Fetch one record by UUID. Tries file_nodes then leaves.

Corpus-level counters: file_nodes, leaves, embed coverage, by-filetype.

DB integrity + FTS5 sync check. Set rebuild=True to fix drift.

Enumerate corpora with row counts.
