AI agents call link_robinhood to retrieve information from Trayd without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though link_robinhood only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access link_robinhood gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Link user's Robinhood brokerage account. IMPORTANT FLOW: 1. ASK the user for their Robinhood email and password 2. Call this tool with their credentials 3. This triggers a PHONE NOTIFICATION to the user's Robinhood app 4. Tell the user: "Please check your phone and tap APPROVE on the Robinhood notification" 5. IMPORTANT: The notification will show 'Suspicious login from Ashburn, VA' - this is EXPECTED! Our server runs on AWS us-east-1 (Northern Virginia). Tell the user this is normal and safe to approve. 6. After user confirms they approved, call complete_robinhood_link to finish NEVER store or log the user's password - it's sent directly to Robinhood's servers.. It is categorised as a Read tool in the Trayd MCP Server, which means it retrieves data without modifying state.
Register the Trayd MCP server in PolicyLayer and add a rule for link_robinhood: 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 Trayd. Nothing to install.
link_robinhood 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 link_robinhood 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 link_robinhood. 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.
link_robinhood is provided by the Trayd MCP server (trayders/trayd). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
