Get information about valid parameter values for NOAA API requests
AI agents call get_parameter_definitions to retrieve information from LocalTides 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 reference information about valid parameter values for API requests. It is a pure read operation with no side effects, data modification, code execution, or destructive capability. The information returned is static reference material. Severity is low because misuse poses minimal risk—an agent could only retrieve publicly available API documentation.
From the tool's definition Tool name 'get_parameter_definitions' and description 'Get information about valid parameter values for NOAA API requests' indicate a retrieval operation with no modification or execution of external code. The tool queries metadata about API parameters.
Attacks that exploit this kind of access
Get information about valid parameter values for NOAA API requests. It is categorised as a Read tool in the LocalTides MCP Server MCP Server, which means it retrieves data without modifying state.
Register the LocalTides MCP Server MCP server in PolicyLayer and add a rule for get_parameter_definitions: 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 LocalTides MCP Server. Nothing to install.
get_parameter_definitions 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_parameter_definitions 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_parameter_definitions. 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_parameter_definitions is provided by the LocalTides MCP Server MCP server (ryancardin15/noaa-tidesandcurrents-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
