## 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 2026-09-21.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 2 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 86/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 323 tokens (~107/item across 3 items; 2 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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 (50% 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 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (2)

### `get_seed_format` (~54 tokens)

Get the Calaf seed file format

Returns the complete specification (markdown) for calaf_seed: 1 JSON documents — the format to follow when a user asks for a Calaf seed. Read it before authoring; then check your draft with validate_seed.

### `validate_seed` (~109 tokens)

Validate a Calaf seed file

Runs a draft seed document through the exact parser the Calaf app imports with. Pass the entire JSON document as a string. Returns per-section counts and the precise issue list (path, severity, message): severity "error" means nothing imports; "dropped" means that row or field is discarded and the rest lands. Fix the issues and validate again until clean before delivering the file to the user.

Input parameters:

- `seed` (required): The complete seed JSON document — as text, or as the JSON object itself.

Output parameters:

- `counts` (object)
- `hasPlanner` (boolean)
- `hasVocab` (boolean)
- `issues` (array)
- `valid` (boolean)
