AI agents call get_room_availability 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 queries and retrieves existing reservation data for display purposes. It has no side effects, does not create, modify, or delete records, and does not execute code or trigger external operations. The blast radius of misuse is minimal—an attacker could only view room schedules, which is low-sensitivity operational data.
From the tool's definition Tool description states 'Get the schedule for a specific room on a given date, showing all booked time slots' — a retrieval operation with no modification, deletion, or execution of external commands.
Attacks that exploit this kind of access
Get the schedule for a specific room on a given date, showing all booked time slots. 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_room_availability: 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_room_availability 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_room_availability 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_room_availability. 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_room_availability 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.
