ChatGPT

ChatGPT talks to Memuron as a custom MCP plugin. One dialog, one URL, one approval — and the assistant stops forgetting what you told it last week.

The same thing, written down

Set up ChatGPT in 4 steps

No API keys to paste, no glue code — sign in once and your agent keeps the memory.

Remote MCP4 steps · about a minute
  1. Open ChatGPT, then Plugins in the sidebar
  2. Click + to create a new plugin
  3. Paste the MCP URL, choose OAuth, tick the notice
  4. Create, then Allow in Memuron
Custom MCP plugins need a paid ChatGPT plan, and on Business, Enterprise, and Edu a workspace owner has to allow them first. A plugin you create is yours alone until an admin publishes it to the workspace.

Search, fetch, and the rest

ChatGPT leans on search and fetch semantics for retrieval, which Memuron serves through memuron_query and memuron_get. The write tools are available too, so the assistant can record decisions as well as recall them.

memuron_list_spaces

Discover which spaces exist before guessing a path.

memuron_query

Pipe semantic search, traversal, and regex over the graph.

memuron_get

Fetch one memory and its links once you have an ID.

memuron_ingest

Queue content for the Guardian to create, update, or link.

memuron_updateconfirm

Patch content or scope on a memory you already found.

memuron_deleteconfirm

Remove a memory — never without an explicit confirmation.

memuron_document_source

Resolve any chunk back to the file and page it came from.

memuron_job_status

Poll an async ingest until the Guardian commits or rejects it.

Start a conversation with “check Memuron first” if you want recall to be reliable rather than opportunistic. The AGENTS.md pack has wording you can paste into a custom instruction.

What the plugin can reach

The OAuth token is bound to a single organization and inherits your member scopes — the plugin cannot see a space you cannot.

One organization

The token is minted against the org you picked at approval. Switching orgs means approving again.

Your scopes only

Spaces you have disabled stay invisible to the plugin, exactly as they are to you.

Auditable writes

Every write lands in the append-only ledger with the connector named as the actor.

When something looks wrong

  • Create stays greyed out. The acknowledgement checkbox under the risk notice is still unticked.
  • Authentication fails immediately. The URL must be the API host ending in /mcp, not the console.
  • Installed, but no tools listed. Reopen the plugin and let ChatGPT re-read the tool manifest; it caches the first handshake.
  • Empty answers. You approved an organization with no spaces enabled for your user. Check space access in the console.
