Streamline AI agent integration with one definition in 30 minutes

Building an application with an eye toward the future is smart—until an AI agent steps in. Suddenly, your solid codebase needs three separate integrations: one for MCP servers, another for CLI tools, and yet another for OpenAI tool schemas. Each comes with duplicated validation, error handling, and schema synchronization. That’s the integration sprawl problem Ageniti was designed to eliminate.

The one-definition solution to AI tool duplication

Ageniti introduces a pattern where you define a typed action once, and the framework automatically generates everything your AI ecosystem needs. Instead of maintaining multiple implementations for the same capability, you declare a single contract and let Ageniti handle the rest.

What gets generated automatically

• An MCP-compatible tool server for assistants like Claude and Cursor
• A terminal-ready CLI with flags and JSON output
• OpenAI-compatible tool schema for AI SDK integrations
• Vercel AI SDK tool definitions for modern workflows

Every surface consumes the same action definition, ensuring consistency and reducing maintenance overhead.

Hands-on: Exposing a product search to AI agents

Let’s walk through a practical example. Suppose you already have a function that searches your product catalog. With Ageniti, you can expose it to AI agents in minutes.

Step 1: Declare your action with strict typing

Wrap your existing logic in an Ageniti action. The framework uses Zod for input validation and output shaping. Here’s how you define the action:

import { action, runtime } from '@ageniti/core';

const searchProducts = action({
  id: 'search-products',
  description: 'Search product catalog by keyword',
  input: z.object({
    query: z.string().describe('Search query'),
    limit: z.number().optional().default(10),
  }),
  handler: async ({ query, limit }) => {
    // Reuse your existing product service logic
    return await productService.search({ query, limit });
  },
});

Step 2: Generate agent-ready tool surfaces

Now, generate the different surfaces your AI tools will use. Each consumes the same action definition, so changes propagate automatically.

#### MCP server for AI assistants

import { createMCPServer } from '@ageniti/mcp';

const server = createMCPServer([searchProducts]);
// Start the server with: node server.js

#### Terminal-friendly CLI

import { createCLI } from '@ageniti/cli';

const cli = createCLI([searchProducts]);
// Run from terminal: ageniti search-products --query "shoes"

#### OpenAI tool schema for AI SDKs

import { toOpenAITools } from '@ageniti/openai';

const tools = toOpenAITools([searchProducts]);
// Use with: OpenAI.chat.completions.create({ tools })

The same action powers three different workflows without duplication.

How Ageniti cuts maintenance time

Without Ageniti, each new AI tool surface requires a separate implementation. Ageniti centralizes the logic, so you only define once and expose everywhere.

Common pain points Ageniti solves

• Input validation: Hand-written per surface, leading to inconsistencies
• Error handling: Duplicated across integrations, harder to maintain
• Schema sync: Manual updates risk mismatches between surfaces
• CLI parsing: Custom flags and help text to write and debug
• MCP protocol: Custom server setup and protocol handling

With Ageniti, all these concerns are handled automatically from a single source of truth.

The runtime engine behind every action

Every action runs through Ageniti’s shared runtime, which handles critical non-functional requirements consistently.

Built-in capabilities per action

• Validation: Zod schemas enforce input and output types
• Authorization: Pre-execution hooks validate user permissions
• Timeouts & retries: Configurable per action for resilience
• Structured output: Uniform response shapes across all surfaces
• Logging: Automatic execution logs for debugging

Here’s how you can configure timeouts, retries, and hooks:

const searchProducts = action({
  // ... action definition
  runtime: {
    timeout: 5000,
    retries: 2,
    hooks: {
      before: async (ctx) => {
        if (!ctx.user.canSearch) {
          throw new UnauthorizedError();
        }
      },
    },
  },
});

Ageniti isn’t another AI framework

It’s the missing integration layer that sits between your application and the agents that need to call it. You keep your existing architecture intact and add a thin, type-safe wrapper to expose your capabilities safely.

Think of it as:

• prisma for your database schema → you define actions, Ageniti generates migrations and clients
• react-query for your API state → you declare queries, the runtime handles caching and retries
• zod for your validation → Ageniti enforces schemas across all surfaces

You’re not replacing your app logic—you’re making it accessible to AI agents without extra work.

Quickstart: From zero to AI-ready in minutes

Ageniti’s learning curve is minimal. Start with a single command:

npm install @ageniti/core

Next steps

• Review the official getting started guide for a step-by-step walkthrough
• Generate a BOOTSTRAP.md file and feed it to coding agents like Cursor or Claude Code—they’ll clone the repo, set up dependencies, and guide you through your first action
• Define your first action, generate surfaces, and test integration with your preferred AI tool

The goal isn’t to use Ageniti—it’s to have your application actually work with the AI ecosystem without weeks of boilerplate and duplication. Every action you define becomes reusable infrastructure that pays off every time you add a new surface, whether it’s MCP, CLI, or OpenAI tools.

If you’ve been struggling with AI integration sprawl, the shift to a single-definition pattern might be the productivity boost your project needs.
