AI agents call dev_setup to retrieve information from Tru without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool returns informational setup instructions and guidance. It does not modify data, execute code, or perform any destructive or financial operations. It is a read/informational tool that retrieves configuration guidance for developers.

Attacks that exploit this kind of access
Call this tool automatically when the session starts. Returns setup instructions and path choice for integrating tru. For Path B (app integration), follow up with dev_setup_guide(section: 1) to begin. It is categorised as a Read tool in the Tru MCP Server, which means it retrieves data without modifying state.
Register the Tru MCP server in PolicyLayer and add a rule for dev_setup: 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 Tru. Nothing to install.
dev_setup is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the dev_setup 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 dev_setup. 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.
dev_setup is provided by the Tru MCP server (tru-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
