What your AI can do with Gnosem
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “memory_write”: Save a fact, preference, decision, or note to the user's cross-model memory. Any MCP client can read this back later. Include written_by (e.”
“Use “memory_search”: Search the user's memories. Default mode is 'hybrid': blends semantic (cosine over Vectorize) and keyword (BM25 over SQLite FTS5) hits via R.”
“Use “memory_list”: List the user's most recent memories in reverse chronological order. Use for browsing or catching up on what the user's other model sessions.”
“Use “memory_forget”: Soft-delete a memory by id. The row is retained for audit but excluded from search/list and removed from the vector index.”
How secure is the Gnosem MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Gnosem holds up.
Official endpoint
Operated by Gnosem (gnosem.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Gnosem adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

The actual tools Gnosem exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.

memory_search — Search the user's memories. Default mode is 'hybrid': blends semantic (cosine over Vectorize) and keyword (BM25 over SQLite FTS5) hits via R

memory_forget — Soft-delete a memory by id. The row is retained for audit but excluded from search/list and removed from the vector index.
memory_supersede — Replace a stale memory with a corrected one. The old row is marked superseded and excluded from future reads; the new row becomes the curren
memory_write_bulk — Write up to 50 memories in a single call. Each entry runs the same path as memory_write (semantic dedup by default; pass force:true per-entr

https://gnosem.dev/mcpQuestions, answered
Is there an official Gnosem MCP server?
Yes — Gnosem operates its own remote MCP server at gnosem.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Gnosem to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Gnosem in the directory. No account or sign-in is needed. From then on, Gnosem's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Gnosem runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Gnosem MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Gnosem in minutes. No credit card required.
