A roadmap your agents can use safely
Cairn has an MCP server. An agent can read the roadmap, propose changes and make a share link, and it never does more than the person it acts for.
The Cairn app is available in English and French.
Read it whole
Every answer fits in about 20,000 characters, even on a roadmap of 200 projects, because an agent cannot use an answer it has to save to a file. A long list comes with a cursor, or a hint that names the call for the rest.
Preview a change before it is saved
Creating or updating a project or a programme takes a dry run flag. The answer shows what would change, and nothing is saved. A bulk update of more than 20 records returns a plan first and applies it only when you confirm.
Access you can see and end
An agent signs in with OAuth through your browser, or uses a token you create. It acts as you, with your role as it is now: if an administrator lowers your role, the access of the agent drops at its next request.
A token has an end date and one of four scopes, read, write, share or full. Settings lists every connected agent and lets you revoke any of them. The change feed names the member and the client behind each change.
What an agent cannot do
No scope can manage members or tokens, delete a project or change the workspace settings. A share link made by an agent shows a short list of fields and expires after 30 days by default, and the agent cannot read the secret of a link back.
Connect in one command
Clients that follow the MCP authorization flow add Cairn with one command and sign in through your browser. We have tested the flow with the official MCP SDK client. Scripts and CI jobs use a token.
