## 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 2026-11-05.

- **Endpoint Security**: 74/100
  - 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 is enforced; there's no plaintext access path.
  - 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**: 79/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 892 tokens (~148/item across 6 items; 5 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 85% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

## MCP tools (5)

### `start_audit` (~129 tokens)

Start an audit of the person's data

Proposes how to read a data file for an audit, from its column names (optionally a type and one example value each) and the results the person wants to publish. Returns a proposed spec (the role of each column, each result written as a claim), how claims are written, the catalog of checks and the points the person has to confirm. It receives no rows.

Input parameters:

- `columns` (array, required)
- `dataset_name` (string)
- `figures` (array): The results the person wants to publish, in their words, e.g. 'share of projects per sector'.

### `measure_in_app` (~161 tokens)

Measure the person's file inside the audit panel

Opens the audit panel in the chat. Without a spec, the panel receives the person's file, reads it in their browser and returns a profile of it: per column its kind, empty cells, distinct values, the values of categories with their counts, the range of numbers and dates, and the first rows. With a confirmed spec, the panel measures that same file in the browser with measure.py and shows one light per result. The file is not sent to this server.

Input parameters:

- `columns` (array): Optional: the column names of the file, to check the spec refers to real columns.
- `spec` (object): The spec from start_audit, as confirmed by the person. Leave it out to open the panel first, to receive the file.

### `prepare_script` (~115 tokens)

Get the script that measures the data

Returns measure.py with a confirmed spec written in: a fixed Python script (standard library, no network, fixed seeds) that counts what each check needs from a data file and prints those counts with its own fingerprint and no rows. Reads .csv or .json. If the spec has errors, returns the errors instead.

Input parameters:

- `columns` (array): Optional: the column names of the file, to check the spec refers to real columns.
- `spec` (object, required): The spec from start_audit, as confirmed by the person.

### `show_audit` (~110 tokens)

Show the lights of the person's audit

Turns the output of measure.py into one light per result (red, amber or green, with its reasons), after checking that the output comes from the unchanged script and from the given spec. Shows the lights in the chat and returns them, with a link to the same view on arquestra.dev that carries only codes. Stores nothing.

Input parameters:

- `output` (string, required): Everything measure.py printed: the fingerprint line and the measures line.
- `spec` (object, required): The same spec sent to prepare_script.

### `example_audits` (~136 tokens)

What the audit is, with worked examples

Published example audits, such as the AI Project Radar, and how the audit works. With no arguments: the overview and the list of examples. With a name: one example, result by result (level filters by light). With a name and an id: one result with every reason and what to change. They are not the person's data.

Input parameters:

- `id` (string): Figure id inside that example.
- `lang` (string): Language of the texts. Default en.
- `level` (string): Only figures with this light.
- `name` (string): Example name from the list, e.g. 'radar'.

### Is the Arquestra Audit MCP server safe to use?

Arquestra Audit scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Arquestra Audit MCP server expose?

Arquestra Audit exposes 5 tools: start_audit, measure_in_app, prepare_script, show_audit, example_audits. Their descriptions and schemas cost roughly 651 tokens of context every time the server is loaded.

### Does the Arquestra Audit MCP server require authentication?

No. We connected to Arquestra Audit without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Arquestra Audit MCP server still maintained?

Arquestra Audit is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
