Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 831 tokens (~207/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
- Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 3 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

compare_mcps ~273
Choosing between several MCP servers that do similar things? This tool decides for you. PAID $0.10 via x402 (USDC micropayment over HTTP 402 — no account or API key needed; on your first call without payment you receive the exact payment requirements, then retry with the X-PAYMENT header). Compares 2-5 MCP servers head-to-head with identical objective checks (handshake, tools/list, documentation coverage, latency, and a safe functional probe — paid tools are never called) and returns: a ranked list, the recommended winner, a plain-language explanation of why it won, and each server's full report — cheaper than separate evaluate_mcp calls on 3+ servers. Objective checks only — no human and no LLM opinion; it does not judge the real-world usefulness or safety of the content. Set 'urls' (required) to an array of 2-5 MCP endpoints (Streamable HTTP), e.g. ["https://a/mcp","https://b/mcp"].
| Name | Type | Req | Description |
|---|---|---|---|
| urls | array | yes | An array of 2-5 target MCP server endpoints (Streamable HTTP) to compare, e.g. ["https://motherwise-api.onrender.com/mcp", "https://mcp-judge.onrender.com/mcp"]. Required. |

evaluate_mcp ~286
Call this BEFORE integrating any third-party MCP server: an unreliable or undocumented MCP wastes your tokens and can break your workflow. PAID $0.05 via x402 (USDC micropayment over HTTP 402 — no account or API key needed; on your first call without payment you receive the exact payment requirements, then retry with the X-PAYMENT header). Returns a complete objective quality report on the target: protocol conformance ('initialize' handshake), tool discovery via 'tools/list', per-tool and per-parameter documentation coverage, latency, and a safe functional probe — free tools are actually called, paid tools are only verified to be cleanly declared (MCP Judge never pays). You get a 0-100 score, A-F letter grade, per-criterion breakdown, and a plain-language summary you can act on. Tip: run the FREE quick_check first to get just the grade, and list_criteria to see exactly how scoring works. Objective checks only — no human and no LLM opinion; it does not judge the real-world usefulness or safety of the content. Set 'url' (required) to the target's MCP endpoint (Streamable HTTP), e.g. https://host/mcp.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | The target MCP server endpoint (Streamable HTTP), e.g. https://motherwise-api.onrender.com/mcp. Required. |

list_criteria ~93
FREE, no payment required. Full transparency into what you pay for: returns the exact criteria MCP Judge uses to score an MCP server — each criterion, its weight out of 100, and the A-F grade scale. Call this to understand how quick_check, evaluate_mcp and compare_mcps score targets before paying. The evaluation is fully objective and automated — no human reviewer and no AI opinion. Takes no parameters.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
quick_check ~179
FREE, no payment required. Instant trust check of any MCP server: returns only the 0-100 score, A-F grade, tool count, latency and a one-line verdict — no detailed report. Use this FIRST, before integrating any third-party MCP server, to see at a glance whether it is technically trustworthy; an unreliable MCP wastes your tokens and can break your workflow. For the full actionable report (per-tool documentation coverage, functional probe results, score breakdown, plain-language summary) call evaluate_mcp; to pick between alternatives call compare_mcps. Set 'url' (required) to the target's MCP endpoint (Streamable HTTP), e.g. https://host/mcp.
