Get list of stations
AI agents call get_stations 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 information without creating, modifying, deleting, executing code, or moving funds. It is a simple data query analogous to a search or list operation. Blast radius is minimal since reading station information poses no security risk.
From the tool's definition Tool name 'get_stations' and description 'Get list of stations' indicate a retrieval operation with no side effects. Fetches publicly available NOAA station metadata.
Attacks that exploit this kind of access
Get list of stations. 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_stations: 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_stations 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_stations 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_stations. 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_stations 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.
