WHAT IT DOES

What add_bookmark does on AirMCP

AI agents use add_bookmark to create or update resources in AirMCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AirMCP environment.

RISK

Why add_bookmark is rated Medium

The tool's intent is to write/create a bookmark (reversible modification), which places it in the Write category. However, because the tool is deprecated and explicitly returns errors on current systems, the actual risk is minimal. The low severity reflects that the tool cannot execute its intended action, making real-world misuse unlikely.

From the tool's definition Tool name 'add_bookmark' indicates creation/modification of bookmarks; description states it is deprecated and non-functional on current macOS versions ('returns an error on unsupported hosts').

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_bookmark safely

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

add_bookmark Rate-limited

add_bookmark 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.

          "max": 30,

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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