MCP Endpoint Health Monitor

An HTTP 200 is not an MCP health check. This Actor validates public Streamable HTTP endpoints at the protocol layer: JSON-RPC shape, current stateless discovery, compatibility initialization, version negotiation, tool discovery, latency, and authentication boundaries.

Checks

MCP 2026-07-28 server/discover
Compatibility fallback to the 2025-11-25 initialize handshake
JSON-RPC 2.0 response validity
tools/list and discovered tool names
HTTP status and aggregate latency
Clear auth-required, degraded, unreachable, and invalid states

Security boundaries

Version 1 accepts unauthenticated public HTTP(S) endpoints only. It rejects credentials embedded in URLs and blocks DNS targets that resolve to private, loopback, link-local, benchmark, multicast, or metadata-network ranges. Redirects are not followed.

Automation

Add up to 50 endpoints, schedule the Actor in Apify, and connect the dataset or webhook to your monitoring workflow. Each endpoint produces one structured dataset item; the complete run summary is stored in the REPORT key-value record.
