TOOL_BUILDING

Build AI tools without code

Your CMO builds an email generator. Your legal team builds a contract reviewer. No engineers required—just expertise captured in tools anyone can use.

01 / Guided Creation

From idea to production in 5 minutes

Our AI-powered wizard guides you through building professional-grade tools. No prompt engineering experience needed.

Step 1: Define your tool

Start with a simple description of what you want. Our AI understands natural language and helps you shape your idea into a production-ready tool.

01Give it a name that's clear and descriptive
02Describe what it does in plain English
03AI generates an MCP-compliant identifier
04Choose who can access it: private, team, or company
ID

Auto-generated ID

on_brand_email_generator

02 / Under The Hood

Production-grade tool architecture

Every tool you build is MCP-compliant, secure, and ready for enterprise deployment.

tool_schema.ts
interface Tool {
  id: string;
  name: string;                    // MCP-compliant: lowercase_with_underscores
  display_name: string;            // Human-readable: "On-Brand Email Generator"

  system_prompt: string;           // The AI's instructions
  input_schema: JSONSchema;        // Validated inputs

  metadata: {
    category: string;              // For discovery
    tags: string[];
    access_control: 'private' | 'team' | 'company';

    // Context integration
    context_hints: string[];       // Auto-inject these contexts
    context_exclusions: string[];  // Never inject these
    context_format: 'legacy' | 'xml';

    // Review workflow
    review_trigger: 'none' | 'always' | 'conditional';
    review_category?: string;
  };

  // Server-side capabilities
  composable_functions?: ComposableFunction[];
}
