What tower_detail does on Fccdb
AI agents call tower_detail to retrieve information from Fccdb without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why tower_detail is rated Low
This is a read-only data retrieval tool that queries FCC database records about antenna tower structures and related license information. It has no side effects, makes no modifications, executes no code, and poses minimal risk even if misused by an AI agent—it only surfaces publicly-available FCC regulatory data.
From the tool's definition Tool retrieves and returns full data about antenna structures (owner, location, height, licensees, microwave paths) by ASR registration number.
Attacks that exploit this kind of access
The rule that runs tower_detail safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Fccdb, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tower_detail, this is the rule to start with:
tower_detail is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Fccdb, apply this rule, and every tower_detail call is checked against it from then on.
Questions about tower_detail
Full data for an antenna structure by ASR registration number — owner, location, height, declared licensees on the tower, microwave paths terminating there, and licensees within 50 m by spatial proximity. Returns Markdown. It is categorised as a Read tool in the Fccdb MCP Server, which means it retrieves data without modifying state.
tower_detail accepts 1 parameter: asr_number. Required: asr_number. The full parameter table on this page comes from the server's own tool schema.
Register the Fccdb MCP server in PolicyLayer and add a rule for tower_detail: 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 Fccdb. Nothing to install.
tower_detail 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 tower_detail 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 tower_detail. 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.
tower_detail is provided by the Fccdb MCP server (https://fccdb.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
