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

Write a tool call result to the persistent, signed audit log. Call this AFTER tool execution with the outcome. Each entry is cryptographically signed for tamper-evidence. Essential for compliance, DORA, MiCA audit trail requirements.. It is categorised as a Write tool in the Agentguard MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agentguard MCP server in PolicyLayer and add a rule for audit_log_write: 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 Agentguard. Nothing to install.
audit_log_write 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 audit_log_write 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 audit_log_write. 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.
audit_log_write is provided by the Agentguard MCP server (https://feedoracle.io/guard-oracle/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
