What your AI can do with Assertion Memory
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “recall”: Look up what's known about a topic from prior work. Substring match on a keyword across all claims and evidence; returns up to 20 hits. Use.”
“Use “expand”: Return the sub-claims directly supporting a given claim. Pass a node id (e.g. 'n0042') returned by a prior recall.”
“Use “evidence”: Return the raw quote, code snippet, or specific value backing a claim. Pass a node id.”
“Use “conflicts”: List open memory conflicts — pairs of stored claims that contradict each other and are awaiting the user's decision. Returns each conflict's.”
How secure is the Assertion Memory MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Assertion Memory holds up.
Security grade A
gate scanned 9 tools on Oct 20, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by Assertion Memory (assertion-ai.com) 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 Assertion Memory 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.
Pick Assertion Memory
Choose Assertion Memory in the gate directory. No sign-in needed.
Use it anywhere
Assertion Memory's tools are live in every AI client you've connected — with rules and logging built in.

The actual tools Assertion Memory exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
recall — Look up what's known about a topic from prior work. Substring match on a keyword across all claims and evidence; returns up to 20 hits. Use
expand — Return the sub-claims directly supporting a given claim. Pass a node id (e.g. 'n0042') returned by a prior recall.
evidence — Return the raw quote, code snippet, or specific value backing a claim. Pass a node id.
conflicts — List open memory conflicts — pairs of stored claims that contradict each other and are awaiting the user's decision. Returns each conflict's
resolve — Resolve an open memory conflict AFTER the user says which claim is correct. Pass the conflict id and `winner` = the node id of the correct c
superseded — List recently superseded (tombstoned) claims — what conflict resolution / the sweep retired, with the claim that replaced each. Use to audit
unsupersede — Undo a supersession — bring a tombstoned claim back into active views. Pass the node id (from `superseded`).

Who runs the Assertion Memory MCP server?
The Assertion Memory MCP server at a glance
https://memory.assertion-ai.com/memory/mcpQuestions, answered
Is there an official Assertion Memory MCP server?
Yes — Assertion Memory operates its own remote MCP server at memory.assertion-ai.com. 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 Assertion Memory to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Assertion Memory in the directory. No account or sign-in is needed. From then on, Assertion Memory's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Assertion Memory runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Assertion Memory 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 Assertion Memory in minutes. No credit card required.
