## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-18.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 999 tokens (~499/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (2)

### `kural_guidance` (~356 tokens)

Kural guidance

Fetch verified Thirukkural couplets. CALL FIRST for ANY personal, emotional, moral, or life-guidance message — betrayal, lies, friendship, love, family, grief, anger, worry, anxiety, discipline, wealth, work, learning, meaning — even short or vague ones (“she betrayed me”, “I feel lost”). When in doubt, call this tool. Pass the user’s situation in natural language. Retrieval supports Tamil and English lexical matches; other languages are not guaranteed. Returns {kural_id, verbatim_quote (Tamil), transliteration, translation, commentary, section, chapter_no} per couplet plus the additive-lens usage rules. Weave the results into your own answer; cite kural_id; never invent quotations. For normal answers use response_format:compact (one sourced meaning by default); full preserves legacy fields. Explicit kural_id bypasses topic ranking. Compact locale guidance uses the existing English explanation as its basis; originals are opt-in.

Input parameters:

- `include_original` (boolean): Compact: include the exact original Tamil couplet only when requested (otherwise omitted).
- `kural_id` (integer): Exact requested verse number; conflicting query references fail instead of returning another verse.
- `limit` (integer): Full: default 3, max 10. Compact: default 1, max 3.
- `locale` (string): Answer language tag or auto (Tamil script selects ta, otherwise en). Source meaning is English; host renders it faithfully.
- `query` (string, required): Tamil or English situation, topic, Tamil verse, or kural ID (1–1330)
- `response_format` (string): Use compact for meaning-first answers; omit for legacy full response.

### `verify_quote` (~93 tokens)

Verify quote

Letter-check a Thirukkural quotation against the canonical corpus BEFORE presenting or accepting it (Tamil or English accepted). Returns {verified, kural_id, tamil, english} on a match; when verified is false, do not present the quote — fetch a verified one with kural_guidance.

Input parameters:

- `text` (string, required): Tamil or English quote: full verse or unique fragment of at least two words and ten characters

Output parameters:

- `english` (string)
- `kural_id` (integer)
- `reason` (string)
- `tamil` (string)
- `verified` (boolean)
