Find the legal land description for given GPS coordinates (PLSS or Texas TXSS).
AI agents call coordinates_to_plss to retrieve information from Townshipamerica without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads public land survey data and returns corresponding legal descriptions based on input coordinates. No data is created, modified, deleted, or financial transactions occur. The operation is a straightforward data retrieval/transformation task with no side effects or irreversible consequences.
From the tool's definition Tool performs coordinate-to-PLSS lookup/conversion, which retrieves and transforms existing geographic data without modifying, deleting, or executing external operations. Description explicitly states 'Find the legal land description' — a query operation.
Attacks that exploit this kind of access
Find the legal land description for given GPS coordinates (PLSS or Texas TXSS). It is categorised as a Read tool in the Townshipamerica MCP Server, which means it retrieves data without modifying state.
Register the Townshipamerica MCP server in PolicyLayer and add a rule for coordinates_to_plss: 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 Townshipamerica. Nothing to install.
coordinates_to_plss 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 coordinates_to_plss 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 coordinates_to_plss. 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.
coordinates_to_plss is provided by the Townshipamerica MCP server (townshipamerica/python-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
