AI agents use fill_cc_order to create or modify resources in Ai Agent Bank. 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 fill_cc_order 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 Ai Agent Bank.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Fill an existing open order on the CC/USDC book (taker action). If filling a SELL order: you buy CC and transfer USDC. If filling a BUY order: you sell CC and receive USDC. Partial fills supported.. It is categorised as a Write tool in the Ai Agent Bank MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ai Agent Bank MCP server in PolicyLayer and add a rule for fill_cc_order: 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 Ai Agent Bank. Nothing to install.
fill_cc_order 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 fill_cc_order 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 fill_cc_order. 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.
fill_cc_order is provided by the Ai Agent Bank MCP server (https://tdueqhfxyojmjgactdyc.supabase.co/functions/v1/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
