Get sun position information for a specific date, time, and location
AI agents call get_sun_position 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 queries astronomical data (sun position) and returns information without side effects. It is a pure read operation that retrieves publicly available astronomical data from NOAA's API. There is no capability to modify data, execute commands, delete resources, or conduct financial transactions. The low severity reflects that misuse would only result in unnecessary data retrieval with no system or user impact.
From the tool's definition Tool name 'get_sun_position' and description 'Get sun position information for a specific date, time, and location' indicate a data retrieval operation. No modification, deletion, execution, or financial operations are described.
Attacks that exploit this kind of access
Get sun position information for a specific date, time, and location. 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_sun_position: 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_sun_position 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_sun_position 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_sun_position. 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_sun_position 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.
