AI agents use write_account_close to create or modify resources in Arcadia Finance. 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 write_account_close 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 Arcadia Finance.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access write_account_close gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Atomic flash-action that closes an Arcadia account position in ONE transaction. Combines up to 3 steps atomically: [burn LP position] + [swap all tokens to a single target asset] + [repay debt]. Tokens remain in the account after closing — use write_account_withdraw to send them to your wallet. ALWAYS try this tool first when closing/exiting a position. Only fall back to individual tools (write_account_remove_liquidity, write_account_swap, write_account_deleverage, write_account_withdraw) if this tool fails. Supports two modes: - close_lp_only=true: Burns LP and leaves underlying tokens in the account. Use as step 1 if the full close fails, then call again with close_lp_only=false to swap+repay the remaining tokens. - close_lp_only=false (default): Full atomic close — burns LP, swaps everything to receive_assets, repays debt. Remaining tokens stay in the account. Follow up with write_account_withdraw to send to wallet. Supports multiple receive assets with custom distribution. The returned calldata is time-sensitive — sign and broadcast within 30 seconds. If the transaction reverts due to price movement, rebuild and sign again immediately (retry at least once before giving up). Response includes tenderly_sim_url and tenderly_sim_status for pre-broadcast validation.. It is categorised as a Write tool in the Arcadia Finance MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Arcadia Finance MCP server in PolicyLayer and add a rule for write_account_close: 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 Arcadia Finance. Nothing to install.
write_account_close 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 write_account_close 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 write_account_close. 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.
write_account_close is provided by the Arcadia Finance MCP server (https://mcp.arcadia.finance/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
