WHAT IT DOES

What trace_state_init does on Trace

AI agents call trace_state_init to retrieve information from Trace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why trace_state_init is rated Low

Even though trace_state_init only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs trace_state_init safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Trace, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For trace_state_init, this is the rule to start with:

trace_state_init Allowed

trace_state_init is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "trace_state_init": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Trace, apply this rule, and every trace_state_init call is checked against it from then on.

FAQ

Questions about trace_state_init

What does the trace_state_init tool do? +

Initialize structured execution state for a task (arXiv:2608.26263). Saves state to SQLite and returns compact initial state. It is categorised as a Read tool in the Trace MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on trace_state_init? +

Register the Trace MCP server in PolicyLayer and add a rule for trace_state_init: 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 Trace. Nothing to install.

What risk level is trace_state_init? +

trace_state_init is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit trace_state_init? +

Yes. Add a rate_limit block to the trace_state_init 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 trace_state_init completely? +

Set action: deny in the PolicyLayer policy for trace_state_init. 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 trace_state_init? +

trace_state_init is provided by the Trace MCP server (nikolai-vysotskyi/trace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
