setup_inicial · Maestro MCP: Risk & Policy

WHAT IT DOES

What setup_inicial does on Maestro

AI agents use setup_inicial to create or update resources in Maestro — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Maestro environment.

WHY IT NEEDS A POLICY

Why setup_inicial needs a policy

This tool writes/persists global configuration settings. While not destructive (changes are reversible), it modifies system state that affects subsequent operations. Severity is high because misconfigured global settings by an unreliable agent could degrade or break the entire development pipeline.

From the tool's definition Tool name 'setup_inicial' combined with description '[Interno] Salva configuração global' (Internal - Saves global configuration) indicates the tool creates or modifies configuration state persistently.

Verdict

setup_inicial Rate-limited

setup_inicial stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about setup_inicial

What does the setup_inicial tool do? +

[Interno] Salva configuração global. Use. It is categorised as a Write tool in the Maestro MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on setup_inicial? +

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

What risk level is setup_inicial? +

setup_inicial is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit setup_inicial? +

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

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