MCP OAuth Debugger for Self-Hosted AI Apps
Build a developer tool that runs end-to-end MCP and OAuth diagnostics for self-hosted AI integrations and pinpoints whether failures stem from token issues, transport hangs, proxy behavior, or client-specific request patterns. The discussion shows strong pain around misleading auth errors that hide protocol defects, making a focused debugging product commercially credible.
Pourquoi c'est important
You connect an AI client to your self-hosted automation stack, watch consent succeed, and assume you are done. Then the connector throws a credential error even though the token is valid. To figure out what happened, you end up tracing registrations, decoding tokens from storage, replaying requests manually, testing refresh grants, and watching proxy logs. The hardest part is not that the system failed; it is that the visible error sends you in the wrong direction. Existing tools help inspect pieces of the flow, but none give you a single explanation of what broke across OAuth, HTTP method handling, and streaming behavior.
- · Conçu pour DevOps teams, platform engineers, and technical founders running self-hosted workflow or automation tools that expose MCP endpoints to AI clients..

Périmètre MVP · 1–2 semaines
- Build a test runner that executes dynamic registration, auth-code exchange, refresh grant, POST initialize, and SSE GET checks against a supplied MCP base URL
- Implement structured result capture for status codes, timeouts, headers, and body fragments
- Create rule-based diagnostics for common mismatches such as token audience confusion versus transport timeout
- Add a secure web form for endpoint configuration and local token handling policies
- Ship a simple report page that labels each flow step pass, fail, or inconclusive
- Add proxy-aware request tracing fields so users can compare direct and tunneled behavior
- Implement reproducible curl export for each failed step
- Add a knowledge base of likely root causes mapped to observed failure signatures
- Launch a lightweight billing wall with free trial and paid saved reports
- Publish targeted landing pages for common MCP and OAuth failure patterns
Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1The initial market may be too narrow if only a small fraction of developers are deploying MCP servers today.
- 2Major workflow and AI vendors could release built-in diagnostics quickly, reducing the value of a standalone tool.
- 3Security-conscious teams may refuse to use a hosted product that touches authentication flows unless a self-hosted option exists.
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
Most of the discussion revolved around a failed AI connector flow that looked like an authorization problem but was ultimately traced to a hanging stream request. Several participants used manual database inspection, command-line replays, token refresh tests, and network logging to isolate the issue. That pattern strongly suggests a recurring need for software that automates protocol diagnosis and explains failures across auth and transport layers.
