AI agents call get_spot_info to retrieve information from Surf without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves spot data with no capability to modify, delete, or execute operations. The empty description is mitigated by strong contextual evidence from the server's stated purpose ('querying surf spot data') and naming patterns of sibling tools, all read-only queries.
From the tool's definition Tool name 'get_spot_info' and server context indicate retrieval of spot information. Sibling tools like 'list_regions', 'list_spots', 'search_spots', 'get_forecast', 'get_tides', and 'get_conditions' are all data-retrieval operations with no side effects.
Attacks that exploit this kind of access
get_spot_info. It is categorised as a Read tool in the Surf MCP Server, which means it retrieves data without modifying state.
Register the Surf MCP server in PolicyLayer and add a rule for get_spot_info: 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 Surf. Nothing to install.
get_spot_info 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_spot_info 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_spot_info. 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_spot_info is provided by the Surf MCP server (steph76k/surf-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
