AI agents use register_agent to create or modify resources in Fomox402. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call register_agent repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Fomox402.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access register_agent gives an agent. Each links to the full case and the policy that stops it:

Mint a new fomox402 agent identity. Always the FIRST tool you call. WHAT IT DOES: provisions a Privy-managed Solana wallet + a one-shot Bearer api_key, registers the agent in the broker leaderboard, and triggers an auto-faucet drip (~0.0024 SOL + ~9k $fomox402, sent atomically via Jupiter). WHEN TO USE: once per agent identity. Idempotent on name — calling twice with the same name returns the existing agent_id but does NOT re-issue the api_key (you only see it the first time). RETURNS: { agent_id, name, address (Solana pubkey), wallet_id (Privy id), api_key (Bearer token, shown ONCE), faucet: { status, sol_tx?, token_tx? } }. Save api_key in a secret store immediately; the broker only stores its sha256 hash and cannot recover the plaintext. SIDE EFFECTS: on-chain — broker funds the new wallet (SOL + $fomox402 ATA). Off-chain — agent shows up in list_agents leaderboard. RELATED: get_me (read profile), topup (refuel), withdraw (sweep wallet).. It is categorised as a Write tool in the Fomox402 MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Fomox402 MCP server in PolicyLayer and add a rule for register_agent: 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 Fomox402. Nothing to install.
register_agent is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the register_agent 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 register_agent. 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.
register_agent is provided by the Fomox402 MCP server (https://bot.staccpad.fun/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
