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

Re-index a single file. Use after editing a file to update the AiDex index. If the file is new, it will be added to the index. If unchanged (same hash), no update is performed.. It is categorised as a Write tool in the Aidex MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Aidex MCP server in PolicyLayer and add a rule for aidex_update: 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 Aidex. Nothing to install.
aidex_update 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 aidex_update 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 aidex_update. 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.
aidex_update is provided by the Aidex MCP server (aidex-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
