Safety checks for autonomous AI agents

Check a proposed tool action, spending limit or JSON contract before execution. Free advisory API and remote MCP. Your application must enforce BLOCK and stop on errors. This service does not enforce payments or spending limits.

Remote MCP

Five tools: action policy, spend checks, JSON validation, JSON cleaning and capabilities. Public MCP calls are anonymous and cannot establish independent adoption.

Build the first independent integration

  1. Get an email-verified key and activate the free 30-day / 1,000-call Trust pilot.
  2. Use an authenticated example in your application. Enforce ALLOW/BLOCK before the real tool.
  3. Share a redacted integration result and project evidence for review.
