Start or check an AiDex session. Call this at the beginning of a new chat session to: (1) detect files changed externally since last session, (2) auto-reindex modified files, (3) get session note and last session times. Returns info for "What did we do last session?" queries.

AI agents invoke aidex_session to trigger processes or run actions in Aidex. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
aidex_session can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Start or check an AiDex session. Call this at the beginning of a new chat session to: (1) detect files changed externally since last session, (2) auto-reindex modified files, (3) get session note and last session times. Returns info for "What did we do last session?" queries.. It is categorised as a Execute tool in the Aidex MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Aidex MCP server in PolicyLayer and add a rule for aidex_session: 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_session is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the aidex_session 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_session. 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_session 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.
