search
AI agents call search to retrieve information from OneMap MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'search' tool likely performs location searches or queries against OneMap's geospatial database, consistent with the server's stated purpose of 'location searches, routing, and coordinate conversions.' No write, execute, destructive, or financial capabilities are evident. Even if misused, search operations on a public mapping API pose minimal blast radius.
From the tool's definition Tool named 'search' on a location/mapping API server (OneMap) with sibling tools for coordinate conversion and data retrieval. Description is empty, but context indicates read-only operations.
Attacks that exploit this kind of access
search. It is categorised as a Read tool in the OneMap MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OneMap MCP Server MCP server in PolicyLayer and add a rule for search: 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 OneMap MCP Server. Nothing to install.
search 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 search 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 search. 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.
search is provided by the OneMap MCP Server MCP server (linzele/mcp-onemap). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
