MCP Tools

Eight tools. Filter by what you're doing, then open one for its parameters and an example.

Write path — store, update, delete, or bulk-import memories. Routes internally to the right operation based on params. `upsert` is the default and the one to reach for: it dedupes near-duplicates, extracts CALLS/IS-A/IMPORTS triples (so relational queries work later), and returns a contradiction warning if a conflicting fact already exists. `chunk` and `batch` require Pro+.

Actions

upsert (default)Store or update in place. Near-duplicates update; new content creates. Phrase content relationally ('AuthService calls verify_token') to enable structural queries.

updateEdit an existing memory by id — re-embeds if content changes.

deletePermanently remove one memory by id.

chunkPro+ onlyStore a long document as overlapping searchable chunks. Ideal for RFCs, ADRs, long transcripts.

batchPro+ onlyStore up to 100 memories in one call.

Parameters

contentstringoptionalText to remember. Required for upsert/chunk; one item in batch.

namespacestringoptionalLogical group. Default: 'default'

tagsstring[]optionalLabels for later filtering

priorityinteger 0–10optionalRetrieval priority (default 5). Use 8–10 for hard constraints.

metadataobjectoptionalArbitrary key-value pairs. Set metadata.skill_name to enable skill_load by name.

idstringoptionalMemory ID — required for update and delete actions.

action'upsert'|'update'|'delete'|'chunk'|'batch'optionalDefaults to 'upsert' when content is provided without an id.

similarity_thresholdnumberoptionalDedup strictness 0–1 (default ~0.85). Lower = more aggressive dedup.

chunk_sizenumberoptionalWords per chunk for action:'chunk'

itemsobject[]optionalArray of memory objects for action:'batch'. Max 100.

Returns

upsert → { id, namespace, action: "created"|"updated", triples_extracted[]?, contradiction? } | chunk → { parent_id, chunk_ids[], chunk_count } | batch → { stored, results[] } | update/delete → { id, status }
