Look up a specific bid by its bid number from the database.
AI agents call lookup_bid to retrieve information from GeM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns information about a specific bid using its bid number as a lookup key. There is no indication that it modifies, deletes, or executes operations—it simply queries and returns existing data. The blast radius of misuse is minimal, as an agent could only view procurement data it is authorized to access.
From the tool's definition Tool name 'lookup_bid' combined with description 'Look up a specific bid by its bid number from the database' indicates a retrieval operation.
Attacks that exploit this kind of access
Look up a specific bid by its bid number from the database. It is categorised as a Read tool in the GeM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GeM MCP Server MCP server in PolicyLayer and add a rule for lookup_bid: 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 GeM MCP Server. Nothing to install.
lookup_bid 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 lookup_bid 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 lookup_bid. 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.
lookup_bid is provided by the GeM MCP Server MCP server (r3tr056/gem_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
