AI agents call get_reservation 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 returns a single reservation record. It performs a read-only lookup operation without creating, modifying, deleting, or executing any actions. The retrieval of reservation details poses minimal security risk as it accesses existing data that is likely already visible to authorized users within the reservation system.
From the tool's definition Tool name 'get_reservation' and description 'Get a single reservation by its ID' indicate a retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
Get a single reservation by its ID. 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_reservation: 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_reservation 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_reservation 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_reservation. 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_reservation 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.
