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 → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability65
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 333 tokens (~111/item across 3 items; 3 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.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.
- 5 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.
- 3 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_claim Check a claim ~95
Find the claims in a text and check the ones plain code can: arithmetic (PROVEN or FALSIFIED), primes, unit conversions. A famous unsolved problem (P vs NP, the Riemann hypothesis) is OPEN. Anything else is NOT CHECKED, which never means false, with a next step.
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | The sentence or answer to check, e.g. "2+2=5" |
No output schema declared.
No examples provided.
lookup_fact Look up a proven fact ~89
Search the library of machine-checked facts. Compact by default (claim start, label, receipt link); set detail true for the full wording.
| Name | Type | Req | Description |
|---|---|---|---|
| detail | boolean | – | Full claim, what checked it and what is not proven |
| max_results | integer | – | How many matches, at most 25 |
| query | string | yes | Words about the fact, e.g. "root theorem" |
No output schema declared.
No examples provided.
search_attempts Search past P vs NP attempts ~81
Search the list of past attempts at P vs NP. Rows are labeled SOURCED, GUESS or NOT TRACED. A match is a warning sign, never a verdict.
| Name | Type | Req | Description |
|---|---|---|---|
| max_results | integer | – | How many matches, at most 25 |
| query | string | yes | Words about your idea, e.g. "linear programming TSP" |
No output schema declared.
No examples provided.
How do I install the Humanities Helping Hands checker MCP server?
Humanities Helping Hands checker is a hosted endpoint at https://humanitieshelpinghands.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
