Recall instead of resend.
ChatGPT takes a remote MCP server by URL in developer mode. Give it this address and sign in.
https://context.tileward.com/mcp/connect
Turn on developer mode under Settings → Security and login, then open Plugins, select the plus button, and create a developer-mode app for a remote MCP server: paste that URL and choose OAuth. The menu path has moved more than once (Plugins was Connectors), so look for developer mode and a plus button that adds an MCP server. Developer mode is available on Plus, Pro, Business, Enterprise and Education accounts on the web; a workspace admin can switch it off or allowlist specific apps, so check with them if you do not see it.
This address signs you in with your Tileward account. The bare context.tileward.com used in config files, without /mcp/connect, takes an API key instead, which the connector dialog has nowhere to put; paste that one here and you get a sign-in error that says so.
Then ask ChatGPT to remember something, start a new chat, and ask it to recall. That round trip is the whole product.
Governed chat goes through the API.
Governance refuses a prompt before the model sees it. That needs a hook the client runs before sending your message, and ChatGPT does not have one.
Coding agents such as Claude Code and Codex expose that hook, so the gate runs there. A connector, a custom GPT or a system prompt only offers the model a tool it may choose to call, which is not a control.
For governed chat today, call the API: the guard runs on our side of the request, so anything that calls Tileward gets the same decision and the same audit record. The addresses are on the endpoint table.
What the connector can see.
Every tool becomes available
A custom connector exposes everything the server offers, reads and writes alike, subject to your confirmation settings. Tileward Context includes tools that delete stored conversations and one that purges an account and is not undoable. Review the confirmation settings rather than approving by reflex.
What we receive
The turns you ask it to remember, and your recall queries. Storage is per account, never pooled with another tenant, and never used to train anything.
