Memory for AI agents: facts a person approved, each with a link, and answers that cite them.

What it does

FactoGraph is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

6 tools offered to AI assistants

getManual · How to ask a public store and cite its facts, and what it holds: how many facts, from which sources. Read it before the store's other tools.
listFacts · Every fact in a public store, numbered, each number a link to the fact. Cite a fact as its number with its link, [F3](<link>).
ask · Ask a question; the store answers only from its facts, each claim linked to its fact, and checks the answer against them. Stores nothing. Returns the step's state: `waiting` (a prompt to do and answer with replyToPrompt), `running` (call ge
getStep · Where a running step is now: its next prompt, or its result.
replyToPrompt · Answer the prompt a step is waiting on - do the model work in its `system` and `messages` first. Keep answering until the step is done or failed.
createStore · A new, empty FactoGraph store of the person's own: its private link and its MCP connector address. Only after the person said yes to having one. Nothing is stored until the link is first opened. The link is the store's key: give it to them

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
