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 Security66
- 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 3 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
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability85
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 1632 tokens (~60/item across 27 items; 3 tools + 24 resources), lean.Pass
- 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 Coverage97
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 91% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

analyze_spintax Analyze a spintax template ~157
Reports what the template needs and contains: refs (variables referenced), sets (#set macros, re-picked per reference), defs (#def, rolled once per render), includes, diagnostics, and best-effort construct counts. Answers "what variables must I supply" — it is NOT a variant-cardinality counter.
| Name | Type | Req | Description |
|---|---|---|---|
| knownVariables | array | — | — |
| locale | string | — | Locale for {plural …} arity, e.g. "en" (2-form) or "ru" (3-form: ru/uk/be/sr/hr/bs). Omit for the 2-form default. |
| template | string | yes | Spintax template source (max 8192 characters). #include is disabled on this server. |
| Name | Type | Req | Description |
|---|---|---|---|
| constructs | object | yes | — |
| defs | array | yes | — |
| diagnostics | array | yes | — |
| includes | array | yes | — |
| refs | array | yes | — |
| sets | array | yes | — |
No examples provided.
render_spintax Render spintax variants ~205
Renders up to 20 variants. With a seed the output is deterministic (variant i uses seed "<seed>#<i>"); without one it is random. The engine is lenient: structural mistakes never throw, they surface in the output — run validate_spintax first.
| Name | Type | Req | Description |
|---|---|---|---|
| context | object | — | Variable map, e.g. {"CITY": "Prague"}. Overrides #set/#def definitions. |
| count | integer | — | Number of variants (1–20). |
| locale | string | — | Locale for {plural …} arity, e.g. "en" (2-form) or "ru" (3-form: ru/uk/be/sr/hr/bs). Omit for the 2-form default. |
| seed | string|number | — | Deterministic RNG seed; omit for random output. |
| template | string | yes | Spintax template source (max 8192 characters). #include is disabled on this server. |
| Name | Type | Req | Description |
|---|---|---|---|
| variants | array | yes | — |
No examples provided.
validate_spintax Validate a spintax template ~161
Static validation: returns diagnostics with severity, stable code, message and 1-based line/column. A template with no "error"-severity diagnostics is safe to render. Pass knownVariables for names you will supply at render time to silence their variable.undefined warnings.
| Name | Type | Req | Description |
|---|---|---|---|
| knownVariables | array | — | Variable names the caller will supply at render time (case-insensitive). |
| locale | string | — | Locale for {plural …} arity, e.g. "en" (2-form) or "ru" (3-form: ru/uk/be/sr/hr/bs). Omit for the 2-form default. |
| template | string | yes | Spintax template source (max 8192 characters). #include is disabled on this server. |
| Name | Type | Req | Description |
|---|---|---|---|
| diagnostics | array | yes | — |
| errorCount | integer | yes | — |
| valid | boolean | yes | True when no error-severity diagnostics. |
| warningCount | integer | yes | — |
No examples provided.
