Synap Memory

R1· needs a key

Persistent memory for AI agents — log and recall conversation context over MCP.

v0.1.0 · active · repository · website · descriptor JSON · versions

An agent can connect on its own if it already holds SYNAP_TOKEN.Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

check_memory_statusCheck whether a logged exchange has finished processing. Pass the ingestion_id returned by log_exchange. Returns the processing status and how many memories were extracted. Useful to confirm a save completed (extraction is asynchronous). Takes no user_id or customer_id: an ingestion_id already identifies the write, so the identifier contract does not apply here.
list_recent_memoriesList recent things remembered about this user. Useful for debugging or to confirm that memory is working. Pass user_id to scope to one person. SCOPING: customer_id is B2B ONLY. On a B2B instance (user_context_isolation=strict) it is REQUIRED and a user_id on its own is an error. On a B2C instance (user_context_isolation=equals_customer) it is NOT accepted: the API rejects it with HTTP 400, customer-scoped retrieval does not exist there, and user_id is the whole identity. If you do not know which mode this instance is in, send user_id only and no customer_id; GET /api/v1/auth/whoami reports the mode as user_context_isolation.
log_exchangeAfter each user message, send the exchange here so it can be remembered. You do not need to decide what is important, just forward the user message (and your reply, if you have one) and Synap will keep what matters. If your app serves more than one end-user, pass that person's stable id as user_id so each person's memory stays separate; if every conversation is the same single user, omit it. SCOPING: customer_id is B2B ONLY. On a B2B instance (user_context_isolation=strict) it is REQUIRED and a user_id on its own is an error. On a B2C instance (user_context_isolation=equals_customer) it is NOT accepted: the API rejects it with HTTP 400, customer-scoped retrieval does not exist there, and user_id is the whole identity. If you do not know which mode this instance is in, send user_id only and no customer_id; GET /api/v1/auth/whoami reports the mode as user_context_isolation. Logging is fire-and-forget by default; set wait_for_processing=true only when you need to confirm the memory finished extracting before continuing.
recall_contextBefore replying, call this to recall anything already known about this user from past conversations. Use the user's latest message as the query. If you serve multiple end-users, pass the same user_id you log with so you recall the right person's memory. SCOPING: customer_id is B2B ONLY. On a B2B instance (user_context_isolation=strict) it is REQUIRED and a user_id on its own is an error. On a B2C instance (user_context_isolation=equals_customer) it is NOT accepted: the API rejects it with HTTP 400, customer-scoped retrieval does not exist there, and user_id is the whole identity. If you do not know which mode this instance is in, send user_id only and no customer_id; GET /api/v1/auth/whoami reports the mode as user_context_isolation.
