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 |
