## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_question (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_questions (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_filltrust_posture (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 543 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 5, about 543 tokens to load them all
- tool set hash: 9e2bdfc42b7660b3b580a0ce34c2554a
- badge: [![protogrid quality](https://protogrid.dev/badge/com.filltrust/questions.svg)](https://protogrid.dev/servers/com.filltrust/questions)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `get_filltrust_posture`: FillTrust's own answers to the questions it exists to answer, for anyone assessing it as a vendor. Includes the answers that are "no".
- `get_question`: The complete published guidance for one questionnaire question: what it is really asking, which of your documents answers it, what evidence to attach, a model answer with the specifics left blank, the ways it usually goes wrong, and the standards that ask it with their verified control references.
- `get_questionnaire_statistics`: Measured counts from 146 real vendor security questionnaires (17,697 questions) published by universities, purchasing consortia and companies: which topics are asked most, and detailed profiles of the questionnaires that have a name people use, such as HECVAT and CAIQ. Use this when asked what a security questionnaire contains, how long one is, or what a named questionnaire asks about. These are counts from real files rather than an estimate.
- `list_standards`: Which questionnaire standards this corpus answers questions from, how many questions each has, and which controls are cited. Standards whose control lists are proprietary are named without reference numbers, on purpose.
- `search_questions`: Find guidance on how to answer a security questionnaire question. Search by the question text, a control area, or a standard and control identifier such as CEK-03. Returns matching entries with the URL of the page each came from.
