MCP Tools Reference

Distill exposes 7 tools via the MCP protocol. Claude Code calls these automatically based on conversation context.

Memories are captured automatically via the auto-observe pipeline — there is no explicit "remember" tool. The tools below are for reading, searching, and managing existing memories.

search_memory

Hybrid search combining full-text (FTS5/tsvector) and vector similarity (LanceDB/pgvector), merged with Reciprocal Rank Fusion (k=60).

Parameter Type Required Description
query string yes Search query
top_k int no Max results (default: 5, max: 100)
repo string no Filter by repository
agent_id string no Filter by agent

Returns: Compact index (~30 tokens/result) with id, type, snippet, score, est_tokens, level. Use get_memories to fetch full content for relevant results.

get_memories

Fetch full memory details by IDs. Batch multiple IDs in one call.

Parameter Type Required Description
ids list[string] yes Memory IDs to fetch

Returns: Full memory objects including level field (short-term, long-term, or shared).

get_memory

Retrieve a single memory by ID.

Parameter Type Required Description
id string yes Memory ID

update_memory

Re-distill new content and supersede an existing memory. The old memory is soft-deleted.

Parameter Type Required Description
id string yes ID of the memory to update
content string yes New raw content to distill

list_recent

List recent memories as compact index.

Parameter Type Required Description
repo string no Filter by repository
tag string no Filter by tag
type string no Filter by memory type
limit int no Max results (default: 20, max: 100)
agent_id string no Filter by agent

Returns: Compact index including level field (short-term, long-term, or shared).

list_stale

List memories likely stale based on age and access patterns.

Parameter Type Required Description
repo string no Filter by repository
limit int no Max results (default: 20)

Returns: List of stale memory dicts with id, type, snippet, age_days, access_count, survival_score.

forget

Soft-delete a memory. It will no longer appear in search results.

Parameter Type Required Description
id string yes Memory ID to delete
agent_id string no If provided, only deletes if the memory belongs to this agent
