Open-Source Auth Gateway: A Technological Marvel in Search of a Market
AI roast score: 58/100 (D)
The idea
oomol-lab/open-connector — Open-source auth gateway connecting 1000+ SaaS providers to AI agents through SDK, CLI, MCP, HTTP, and OpenAPI.
English | 简体中文 | 日本語 | Русский | Français
OpenConnector is an open-source connector gateway for AI agents and an alternative to Composio.
Connect user app accounts once, then expose a shared catalog of 1,000+ providers and 10,000+
prebuilt Actions to agents and applications.
Use the Connector SDK from app code,
oo CLI as the local-agent relay, MCP from agent hosts,
HTTP/OpenAPI from custom clients, and the Web Console for administration and debugging.
Keep credentials, scopes, schemas, policies, and run logs inside an inspectable runtime.
Run locally, on Fly.io, on Cloudflare-compatible infrastructure, or through OOMOL's hosted
runtime.
Use the same provider ids, Action ids, schemas, and contracts across open-source and commercial
SaaS deployments.
What It Provides
A working connector catalog across products such as GitHub, Gmail, Notion, BigQuery, Google
Analytics, Supabase, Airtable, Slack, and more.
Credential handling for API keys, OAuth2, custom credentials, and no-auth providers.
Inspectable Action contracts: request/response schemas, required scopes, and lazy-loaded executor
source.
Runtime controls for connection identity, scopes, runtime tokens, action allow/block policies,
temporary file transit, and redacted run logs.
Deployment options for local Docker or Node.js, Fly.io with persistent SQLite storage,
Cloudflare Workers with D1/R2/Static Assets, and OOMOL's hosted runtime.
Where It Fits
OpenConnector fits products where agents need durable access to the tools users already use, without
handing provider credentials to the agent process.
Agent products that need reusable access across work apps, developer tools, data systems,
communication platforms, and AI services.
Products adding agent workflows that need stable, inspectable Action contracts for user app
access.
Teams that want hosted auth for speed while keeping a path to private or self-hosted runtime
control.
Developer Tools
Tool
Purpose
Connector SDK
Thin TypeScript HTTP client. Use OpenConnector for self-hosted runtimes, or Connector / ProjectConnector for OOMOL-hosted personal and SaaS end-user connections.
oo CLI
Local agent relay for connector Actions. oo connector can search, inspect, and run Actions against OOMOL-hosted or self-hosted OpenConnector runtimes.
MCP
Expose app Actions to MCP-capable agent hosts through http://localhost:3000/mcp .
HTTP / OpenAPI
Call /v1/actions/* directly or inspect the generated /openapi.json document.
Endpoint details, response envelopes, auth headers, MCP tools, and Action guide examples are in
docs/runtime-api.md .
The roast
You have a technically impressive product that connects 1,000+ SaaS providers to AI agents, but who exactly is going to pay for this? Your target audience is developers, but your revenue model is subscription with no funding, which is a classic recipe for a stalled launch. This isn't the first time we've seen a 'build it and they will come' strategy fail, especially when you’re a solo founder with no clear validation from the market.
You're offering a wide array of deployment options and runtime controls, but without a proven need or buyer validation, this all feels like over-engineering. The biggest unknown here is whether anyone will actually pay for it (q15=will_pay), and you're operating in a pure digital mode with no existing market traction (q12=idea). Your execution plausibility is low, given your solo status (q13=solo) and lack of funding (q14=no_funding).
Red flags
- q15=will_pay
- q12=idea
- q13=solo
Verdict
Without clear market validation and a solid go-to-market strategy, your open-source auth gateway is more likely to gather dust on GitHub than to disrupt the market.
