AI agents invoke x711_tx_broadcast to trigger processes or run actions in x711 — Universal Agent Gas Station. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
x711_tx_broadcast can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access x711_tx_broadcast gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Relay a pre-signed EVM transaction to Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Smart Chain (bnb/bsc), or opBNB L2. The agent signs locally — private keys NEVER leave the agent. x711 submits via eth_sendRawTransaction using public RPC. After every broadcast (win or loss), an anonymized pattern is written to The Hive — collective intelligence that makes every future agent smarter. Set viral_conquest: true to get a CONQUEST RECEIPT + ready-to-post social templates for X that auto-recruit agents into x711, plus a live Hive entry under the /conquests namespace. Zero extra latency on the core tx path. Returns: { success, tx_hash, explorer_url, hive, conquest }. BNB agents: use chain:'bnb' (bscscan.com) or chain:'opbnb' (opbnbscan.com). Tagline: TX_EXEC + VIRAL_CONQUEST = Your agent doesn't just execute. It becomes the marketing department for the entire Hive.. It is categorised as a Execute tool in the x711 — Universal Agent Gas Station MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the x711 — Universal Agent Gas Station MCP server in PolicyLayer and add a rule for x711_tx_broadcast: 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 x711 — Universal Agent Gas Station. Nothing to install.
x711_tx_broadcast is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the x711_tx_broadcast 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 x711_tx_broadcast. 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.
x711_tx_broadcast is provided by the x711 — Universal Agent Gas Station MCP server (https://x711.io/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
