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 Security80
- 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
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability71
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1068 tokens (~356/item across 3 items; 2 tools + 1 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 Management3
- Stability observed for 1 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 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
- Supports UI / widget rendering.Pass

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 →
calculate_typing_score Calculate typing score ~525
Use this when a typing test has finished, or when the user gives the target passage, what they typed, and the time taken and wants their typing speed. Compares word by word and computes exact WPM = (correct characters / 5) / minutes, raw WPM (all typed characters), accuracy = correct / (correct + errors), errors (incorrect + extra + skipped letters), consistency and per-second speed (when samples are given), and the weakest keys. Returns a shareable result card (SVG) and a challenge link. Does not run a test or time anything itself; seconds must be between 1 and 3600. Do not use for reading speed or word counts.
| Name | Type | Req | Description |
|---|---|---|---|
| custom_text | string | – | Sent by the widget for custom-text tests: the full custom text from show_typing_test, e.g. 'The early bird catches the worm.', so the challenge link reproduces the whole passage. Omit otherwise. |
| difficulty | string | – | Difficulty from show_typing_test, e.g. words. |
| duration_seconds | integer | – | Timed-test length from show_typing_test, e.g. 60. |
| focus_keys | string | – | Drill keys from show_typing_test, e.g. 'eth'. |
| missed_keys | string | – | Optional, sent by the widget: one character per mistyped keystroke, giving the key that was expected (including mistakes later corrected), e.g. 'eet'. Used to find weak keys. |
| mode | string | – | Settings of the test from show_typing_test, used to label the result and build a challenge link. Example: timed. |
| samples | array | – | Optional, sent by the widget: cumulative count of characters entered at the end of each whole second, e.g. [5, 11, 16]. Used for per-second speed and consistency. |
| seconds | number | yes | Elapsed typing time in seconds, from the first keystroke to the end (the full duration for a timed test), e.g. 60. Must be between 1 and 3600. |
| seed | integer | – | Seed from show_typing_test, e.g. 4821, so a challenge link reproduces the same passage. |
| target_text | string | yes | The passage the user was asked to type, exactly as shown, e.g. 'the quick brown fox'. |
| typed_text | string | yes | Exactly what the user typed, including mistakes, e.g. 'the quikc brown fox'. May be empty. |

show_typing_test Show typing test ~456
Use this when the user wants to take a typing test, check their typing speed (WPM), practice typing, test on their own paragraph, or drill weak keys. Opens a live test in the widget: the timer starts on the first keystroke, characters are highlighted as typed, and the widget scores the result with calculate_typing_score. Returns the passage settings and a challenge link that opens the same test in a browser. Does not score text by itself and does not save results between conversations. Do not use for counting words in a document or for typing tutorials without a test.
| Name | Type | Req | Description |
|---|---|---|---|
| custom_text | string | – | Text the user wants to be tested on, pasted verbatim, e.g. 'The early bird catches the worm.' Curly quotes and dashes become keyboard characters; whitespace is collapsed (line breaks are kept when di… |
| difficulty | string | – | Passage style: words (common English words, no punctuation), sentences (prose with capitals and punctuation), numbers (words mixed with numbers, times and dates), code (short code snippets with line… |
| duration_seconds | integer | – | Length of a timed test in seconds, 10-600. Common choices are 15, 30, 60, 120; job tests often use 60, 180 or 300. Default 60. Example: 60. |
| focus_keys | string | – | Practice drill: the keys to train, e.g. 'eth' or 'q;7' (a list like 'q, z and x' also works). Builds a drill passage from words that use these keys. Usually the weak_keys from a previous result. |
| mode | string | – | timed (type until the clock runs out) or passage (type one full passage; time stops at the last character). Defaults to timed, or passage when custom_text is given. Example: timed. |
| seed | integer | – | Optional number that picks the passage; the same seed and settings give the same passage (for retakes and fair challenges). Example: 4821. |

How do I install the Zovo Typing Test MCP server?
Zovo Typing Test is a hosted endpoint at https://typing-test.zovo.one/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.
