Integration Expertise.
For Your Coding Assistant.

Integration Expertise, Built In

Your coding assistant can write code. It can't build production-ready integrations. The connector builder agent brings knowledge from thousands of connectors. It doesn't guess. It knows.

Tested Against Real APIs

AI-generated code looks right until it hits a real API. The builder validates syntax, then tests every action against the live provider. What it ships already works.

Works Where You Code

Every new tool means a new UI, a new login, a new workflow. StackOne's AI connector builder plugs into the coding assistant you already use. One command to set up. No context switching.

From Prompt to Production.
You Request. It Builds.

StackOne's builder agent automates the development workflow end to end. Purpose-built for agent integrations. No guesswork.

Production-ready connector, ready for PR

Connector Agent Skills.
Fine-Tuned on 1,000+ Agent Integrations.

API Research & Discovery

Reads the provider's documentation, scans their API specs, and studies existing integrations. It understands the full API before writing a single line of config.

Complete Integration Generation

Generates full connector configs: auth setup, actions with inputs and outputs, field mapping, enum normalization, all following the Falcon connector spec. Not snippets. Complete, modular files.

Live API Testing

Tests every action against the real provider API. Not mocked, not stubbed, real requests, real responses. If a test fails, it diagnoses the issue and fixes it in the same conversation.

Self-Improving Output

Each test run makes the connector better. The agent refines descriptions, catches edge cases, and tightens outputs as the conversation progresses.

Modular File Structure

Outputs organized, production-ready files, not a single block of code to copy-paste. Each resource (employees, time off, jobs) gets its own file, structured for a clean pull request.

Automatic Credential Security

Scrambles sensitive values before anything touches your repo. API keys, OAuth secrets, and tokens are secured automatically, no manual scrubbing needed.

Connector Agent FAQ

The connector builder is an AI agent that interacts with your coding assistant to create connector configurations for the Falcon execution engine. It researches provider APIs, generates production-ready YAML, validates syntax, and tests against live APIs — all inside your coding environment.

It works with any coding assistant — Claude Code, Cursor, Windsurf, GitHub Copilot, and others. One CLI command to set up: npx @stackone/cli agent setup --local.

It does both. After generating connector YAML, the builder validates the syntax and tests every action against the real provider API. If a test fails, it diagnoses and fixes the issue in the same conversation.

The connector agent creates connectors for the Falcon execution engine. It can build custom connectors for any API, or extend existing ones with new actions. What used to take weeks of manual API research and testing now takes hours. StackOne also ships with 200+ pre-built agent connectors across HRIS, ATS, CRM, LMS, and more.

It's in early access. Start free or request a demo to get credentials and begin building connectors with your coding assistant.

Falcon is the execution engine that uses connectors to run actions for production agents on enterprise apps. The builder creates those connectors. They're complementary.
