AI agents invoke axint.session.start to trigger processes or run actions in Axint. 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.

axint.session.start 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.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so axint.session.start only ever does what you allow.

What does the axint.session.start tool do? +

Start an enforced Axint agent session. Writes .axint/session/current.json plus token-scoped session history, refreshes .axint/AXINT_REHYDRATE.md, returns compact operating memory, docs context, a session token, and the exact axint.workflow.check... Use: call at the start of a tool-enabled agent session or after context compaction. Effects: writes .axint/session and rehydration artifacts; no auth or network required.. It is categorised as a Execute tool in the Axint MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on axint.session.start? +

Register the Axint MCP server in PolicyLayer and add a rule for axint.session.start: 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 Axint. Nothing to install.

What risk level is axint.session.start? +

axint.session.start is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit axint.session.start? +

Yes. Add a rate_limit block to the axint.session.start 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.

How do I block axint.session.start completely? +

Set action: deny in the PolicyLayer policy for axint.session.start. 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.

What MCP server provides axint.session.start? +

axint.session.start is provided by the Axint MCP server (@axintai/compiler). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Axint tool call.
