AWS Lambda & Step Functions connector for Vurb.ts. Auto-discovers tagged resources and produces GroupedToolBuilders — so AI agents can invoke your cloud functions natively.

Quick Start

import { initVurb } from '@vurb/core';
import { discoverLambdas } from '@vurb/aws';

const f = initVurb<AppContext>();
const registry = f.registry();

// Auto-discover Lambda functions tagged with Vurb.ts:true
await discoverLambdas(registry, {
    region: 'us-east-1',
    tagFilter: { 'Vurb.ts': 'true' },
});

Features

| Feature | Description | |---------|-------------| | Auto-Discovery | Scans AWS for Lambda functions tagged for MCP exposure | | Step Functions | Trigger and poll state machines as long-running MCP actions | | GroupedToolBuilders | Each Lambda becomes a typed MCP tool with Zod validation | | IAM Integration | Uses your existing AWS credentials and IAM roles | | Multi-Region | Discover across multiple regions simultaneously |

Step Functions

import { discoverStepFunctions } from '@vurb/aws';

await discoverStepFunctions(registry, {
    region: 'us-east-1',
    prefix: 'mcp-',
});
