Features 🧠

Modernized & Advanced Tools (v0.8.0)

add_memory: Stores a memory from text content or structured message arrays.

Inputs: content (string) or messages (array of role/content objects), userId (string), runId / sessionId (string), agentId (string), appId (string), metadata (object), infer (boolean), customInstructions (string), waitForCompletion (boolean, default: true), timeoutMs (number, default: 15000)
Behavior: Cloud V3 additions are asynchronous. By default, this tool polls the background queue until completed. Pass waitForCompletion: false to get the eventId immediately.

search_memories: Searches memories using semantic and BM25 hybrid filters.

Inputs: query (string), userId (string), runId / sessionId (string), agentId (string), appId (string), filters (object), threshold (number), topK (number), rerank (boolean), referenceDate (string)
Behavior: Automatically nests scope variables inside the V3 filters block to prevent API validation errors.

search_memory: Backward-compatible alias for search_memories.

list_memories: Paginated listing of memory records scoped by identifiers.

Inputs: userId (string), runId / sessionId (string), agentId (string), appId (string), filters (object), page (number), pageSize (number)

get_memory: Retrieves a single memory record by its ID.

Inputs: memoryId (string)

update_memory: Modifies the text or metadata of an existing memory.

Inputs: memoryId (string), text (string), metadata (object)

delete_memory: Deletes a specific memory record by ID.

Inputs: memoryId (string)

get_memory_history: Retrieves the audit trail of memory revisions (cloud only).

Inputs: memoryId (string)

get_memory_capabilities: Exposes the feature matrix and support flags of the active backend storage mode.

Inputs: None

batch_update_memories: Performs bulk updates of text contents for multiple memories (cloud only).

Inputs: updates (array of { memoryId: string, text: string } objects)

batch_delete_memories: Performs bulk deletions of multiple memories.

Inputs: memoryIds (array of strings), confirm (boolean, must be true to execute)

rate_memory: Submits quality feedback evaluation for a memory record (cloud only).

Inputs: memoryId (string), feedback (string: positive, negative, very_negative), reason (string, optional)
