How this service works
Inspect any MCP server like a client would: does it connect, which protocol version, does it need sign-in, how fast, how many tools, and which tools have missing or weak descriptions or input schemas. A checklist of fixes for server owners.
Output
Returns a JSON object with: connection success boolean, latency in milliseconds, server name and version, protocol version string, tool count, overall quality score (0-100), authentication requirement indicator, and an array of human-readable problem descriptions (e.g. 'tool X has no description', 'input schema missing for tool Y').
Example use cases
Pre-launch MCP server audit
“Before I publish my MCP server, can you inspect https://api.myproject.com/mcp and give me a full report — does it connect, what protocol version, how many tools, and are there any description or schema problems I need to fix?”
Debugging connection failure
“My MCP server at https://tools.example.com/mcp seems to be having issues. Can you check if it connects at all, how long it takes to respond, and whether it's asking for sign-in?”
Comparing MCP server quality scores
“I want to know how production-ready my MCP server is — can you inspect https://mcp.myapp.io/mcp and give me a quality score along with a checklist of things that need improvement?”
Technical details
Endpoint
GEThttps://manylives.me/paid/mcp/inspect?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically audit or validate an MCP server — especially before publishing, after deployment, or when debugging connectivity or tool-quality issues. It is purpose-built for MCP protocol introspection, providing structured quality scores and fix checklists that generic HTTP health-check or curl-based approaches cannot offer.
Side effects
- Target MCP server is unreachable — returns connects: false with no further data
- Server responds but speaks an unrecognized protocol version
- Auth-gated server blocks inspection before tool list can be retrieved
- Malformed URL input causes parameter validation error
- Target server times out before responding
