MCP Server Probe
x402
MCP Server Probe is a paid API for AI agents from gogeta2-u35175.vm.elestio.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).
Performs a real MCP Streamable HTTP handshake (initialize + tools/list) against a remote MCP endpoint to check reachability, protocol version, available tools, schemas, latency, and OAuth metadata.

How this service works
Real MCP Streamable HTTP handshake (initialize + tools/list, no tool call): reachability, protocol version, tools, schemas, latency, OAuth metadata.
Output
Returns reachability status, MCP protocol version negotiated during handshake, full list of tools with their names and input schemas, round-trip latency measurement, and any OAuth/authorization server metadata discovered from the endpoint — all without invoking any tool call.
Example use cases
Discover tools on new MCP server
“I just set up an MCP server at https://my-agent-server.example.com/mcp — can you probe it and list all the tools it exposes along with their schemas?”
Pre-flight check before agent connection
“Before I connect my agent to https://mcp.acme.ai/mcp, can you check if it's reachable, what protocol version it's running, and how fast it responds?”
Audit OAuth config on MCP endpoint
“Can you probe the MCP endpoint at https://api.partner.com/mcp and pull back its OAuth metadata so I can see how it expects clients to authenticate?”
Technical details
Endpoint
GEThttps://gogeta2-u35175.vm.elestio.app/agents/v1/agent/mcp-probe?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to non-destructively discover what an MCP server offers — its tools, schemas, protocol version, and auth config — before committing to a full connection or tool invocation. Prefer this over a generic HTTP probe when you specifically need MCP protocol-level introspection (initialize + tools/list handshake) rather than just HTTP reachability.
Side effects
- Target URL is unreachable or times out — returns connection error with latency
- Remote server does not speak MCP protocol — returns handshake failure or parse error
- OAuth metadata endpoint absent — returns null for OAuth fields
- Invalid or malformed URL provided — returns input validation error
- Remote server requires auth even for initialize — returns 401/403 with auth details if extractable
