AI agents call get_relay_app_url to retrieve information from Relay MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only generates a URL with pre-filled parameters — it does not execute any transaction, move funds, or modify any state. It is purely a read/generate operation that produces a link for the user to open in their browser. The actual transaction would only occur if the user manually interacts with the Relay UI, making this tool's blast radius very low.
From the tool's definition Generate a deep link to the Relay web app with pre-filled bridge/swap parameters... This is NOT a transaction tracking URL
Attacks that exploit this kind of access
Generate a deep link to the Relay web app with pre-filled bridge/swap parameters. The user can open this URL in their browser to START a new transaction via the Relay UI. This is NOT a transaction tracking URL — do NOT use it to check on an in-progress transaction. For tracking, use get_transaction_status with the requestId. It is categorised as a Read tool in the Relay MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Relay MCP Server MCP server in PolicyLayer and add a rule for get_relay_app_url: 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 Relay MCP Server. Nothing to install.
get_relay_app_url 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_relay_app_url 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_relay_app_url. 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_relay_app_url is provided by the Relay MCP Server MCP server (relayprotocol/relay-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
