AgentProbe – Validate AI agent endpoints across 8 protocols in one URL

Show HN: AgentProbe – Validate AI agent endpoints across 8 protocols in one URL

AgentProbe – Validate AI agent endpoints across 8 protocols in one URL is a business in show hn launch.

Profile

I built AgentProbe to solve a recurring problem: checking whether an AI agent endpoint actually supports the protocols it claims to.Paste a URL, click Validate, get instant verdicts across HTTP, MCP, A2A/AP2, x402, OAuth, MCP Apps, HTML, and ERC-8004.Each layer gets a detail breakdown — tools found, payment networks, SSL status, agent card metadata, AP2 detection, etc.It also exposes a built-in MCP server so agents can trigger validation programmatically.Code: https://github.com/FlowMCP/mcp-agent-validator Stack: Node.js 22, vanilla JS, DigitalOcean App Platform.Would love feedback on the detection approach.

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

It is recorded at the Show HN launch stage.
