AI agents call get_available_rooms to retrieve information from Boma MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only retrieval of room availability information. It queries existing data (list of available rooms) without creating, modifying, deleting, or executing operations. There are no financial implications, and no irreversible changes occur. The blast radius is minimal—misuse would only expose room availability information, not compromise systems or data integrity.
From the tool's definition Tool name 'get_available_rooms' and description 'Get the list of all available rooms/spaces that can be reserved' indicate a query operation that retrieves data without modification or side effects.
Attacks that exploit this kind of access
Get the list of all available rooms/spaces that can be reserved. It is categorised as a Read tool in the Boma MCP MCP Server, which means it retrieves data without modifying state.
Register the Boma MCP server in PolicyLayer and add a rule for get_available_rooms: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Boma MCP. Nothing to install.
get_available_rooms is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_available_rooms rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_available_rooms. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_available_rooms is provided by the Boma MCP server (nicolasvegam/boma-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
