`note`	string	Yes	The note content (Markdown supported).
`incidentId`	string	Yes	UUID of the incident to annotate.
`visibility`	string	—	Where the note is visible: 'internal' (team only, default) or 'public' (posted to the status page).

Parameters from the server's own tool schema.

RISK

Why add_incident_note is rated Medium

An AI agent can call add_incident_note faster than any human can review: one bad instruction and it creates or modifies resources in OneUptime by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_incident_note safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OneUptime, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_incident_note, this is the rule to start with:

add_incident_note Rate-limited

add_incident_note stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect OneUptime, apply this rule, and every add_incident_note call is checked against it from then on.
