AI agents call inspect_platform to retrieve information from Parlay 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 inspect_platform 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 inspect_platform 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.
Inspect a single named venue. Returns available capabilities, market data for the query, and metadata quality flags. Use when the user explicitly names a venue — "show me Polymarket markets on AI", "what's on Kalshi for Q4 inflation", "Manifold markets about geopolitics". For cross-venue queries use search_markets or compare_markets.. It is categorised as a Read tool in the Parlay MCP Server, which means it retrieves data without modifying state.
Register the Parlay MCP server in PolicyLayer and add a rule for inspect_platform: 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 Parlay. Nothing to install.
inspect_platform 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 inspect_platform 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 inspect_platform. 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.
inspect_platform is provided by the Parlay MCP server (https://mcp.parlay.run/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
