What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

log_exchange
After 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 st
check_memory_status
Check 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 ingest
recall_context
Before 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 B2
list_recent_memories
List 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.

Common questions

Is Synap Memory safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 7 days ago, and the latest version (0.1.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

synap-mcp-server

Hosted remote MCP server (Streamable HTTP) that re-fronts the existing Synap public REST operations as MCP tools, so no-code platforms (Gumloop, n8n) can give their agents persistent memory with nothing but a pasted MCP URL and a Bearer token.

It is a stateless adapter — no new backend, storage, or pipeline. Each tool call maps to one existing REST operation, and the incoming Bearer synap_ token is forwarded verbatim to synap-cloud, which owns auth.

Public endpoint (prod): https://synap-mcp.maximem.ai/mcp
Health: https://synap-mcp.maximem.ai/health

Tools

Tool	REST operation	Notes
`log_exchange`	`POST /api/v1/memories/create` (`mode=long-range`)	Forward every turn; extraction decides what persists. `user_id` scopes per end-user, `customer_id` is B2B only (see Scoping); optional `conversation_id`.
`recall_context`	`POST /v1/context/{client\	user\	customer}/fetch `(`mode=fast`)	Hot path; no IDs ⇒ client scope. `customer` scope is B2B only.
`list_recent_memories`	broad `/v1/context/.../fetch` (no query)	Debug / "test my memory". Same scoping rules.
`check_memory_status`	`GET /api/v1/memories/status/{id}`	Takes no scope ids: the `ingestion_id` already identifies the write.

Scoping: one contract, two modes

The REST API enforces this. It is not advice, and it has been live on production since 2026-08-26 07:07 UTC.

Instance mode (`user_context_isolation`)	What to send	What happens otherwise
`equals_customer` (B2C)	`user_id` and nothing else. The user id is the whole identity.	Any `customer_id` is rejected with HTTP 400. `/v1/context/customer/fetch` is not available at all.
`strict` (B2B)	`customer_id` is required, alongside `user_id`.	A `user_id` on its own is an error. Unchanged by this contract.

GET /api/v1/auth/whoami reports the mode as user_context_isolation. This server reads it once per token and refuses a customer_id locally on a B2C instance, so a model gets a sentence telling it what to send instead of a status code it cannot act on. If the mode cannot be read, nothing is refused and the API stays authoritative.

Pass no IDs at all ⇒ client scope (shared per credential), which is valid in both modes. Note: client-scope writes are not surfaced on the dashboard Memories page (relational), so per-user scoping is recommended when dashboard visibility matters. Fill user_id from an n8n expression / Gumloop input, and pass the same value on log_exchange and recall_context so writes and reads address the same person.

Host header. The server disables the MCP transport's DNS-rebinding check (it sits behind a proxy + Bearer auth), so any reverse proxy can forward the real Host — no Host-rewrite hack needed.

Reporting the turn to the anticipation agent

An MCP server is not an agent. It exposes tools to somebody else's agent and is handed one stateless HTTP call at a time, so most of what an agent does is invisible here: the caller's tool calls, its tool results and its reasoning never reach this process, and nothing tells a stateless server that a conversation has ended. Those are not reported, because there is nothing to report.

The turn does exist. log_exchange is handed the user's message and the assistant's reply as arguments. Set MCP_STREAM_EVENTS=true and each logged exchange is also reported as a conversation turn on POST /v1/events/batch, the HTTP door onto the same listening path the gRPC stream feeds, so the anticipation agent sees the turn and not only the memory extracted from it. This server does not use the SDK's gRPC stream, as the other integrations do: it holds no SDK, keeps no state between requests, and every request can carry a different tenant's key, so a stream per key would be an unbounded pool of connections that nothing closes. Moving it onto the SDK would be a rewrite of its transport for a caller that has no use for what the stream brings back.

Nor does it replace anything of Synap's compaction: the caller's agent keeps its own history and no tool here returns a conversation.

It is off by default, on purpose. Turning it on adds a second backend call per log_exchange, writes the turn to conversation history in addition to the long-range document, and runs the anticipation agent, which bills model calls.

It is not on by default for a second reason. Synap extracts from a conversation when it is compacted, which starts once ten messages have been recorded. Recording every exchange as turns *instead of* the long-range document would hold the memory back until then (the next recall_context finds nothing, and there is no ingestion_id to check); recording them *as well* extracts each exchange twice.

What does not change either way: log_exchange still queues the long-range document and still returns the ingestion_id that check_memory_status and wait_for_processing are built on. A turn report is best effort and can never alter what a tool answers. A turn with no user_id or no conversation_id is not reported at all, because the events route requires both.

Test

pip install -e ".[dev]"

pytest -q

Config (env)

Var	Default	Meaning
`SYNAP_API_URL`	`http://synap-cloud:8000`	Backing REST API base URL (internal docker hostname in prod).
`MCP_PORT`	`8090`	Listen port.
`MCP_RECALL_TIMEOUT_S`	`10`	Recall (read) timeout.
`MCP_INGEST_TIMEOUT_S`	`8`	Log/ingest (write) timeout.
`MCP_DEFAULT_MAX_RESULTS`	`10`	Default recall result count.
`MCP_STREAM_EVENTS`	`false`	Also report a logged exchange as a conversation turn for anticipation. See above before enabling.
`MCP_EVENTS_TIMEOUT_S`	`4`	Turn-report timeout. Best effort; a miss never changes a tool's answer.
`LOG_LEVEL`	`INFO`	Log level.
`ENVIRONMENT`	`production`	Reported in `/health`.

No Synap API key is configured on the server — the end user's key arrives per-request as a Bearer token.
