## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-09-25.

- **Supply Chain Security**: 98/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - 43 of 140 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 0 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 551 tokens (~137/item across 4 items; 4 tools + 0 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**: 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.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "queryData" implies "execute" and declares readOnlyHint instead, contradicting what its own name says it does.
  - 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 supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (4)

### `listSources` (~127 tokens)

Discover what SQAI can touch. No arguments: list connected data sources with exact field names, types, and allowed operations — call this before queryData so specs use exact names. With capabilitySearch: search the deterministic computation catalog and get matching modules. With module: list that module's functions with exact signatures. Execution requires a free community login (`sqai login` device registration, or SQAI_API_KEY) — fully offline thereafter.

Input parameters:

- `capabilitySearch` (string): Search the computation capability catalog; returns matching modules.
- `module` (string): List a module's functions with exact signatures.

### `queryData` (~142 tokens)

Execute one deterministic, read-only SQAI request. Use kind 'query' for tabular questions (aggregations, grouping, filtering) over connected sources — call listSources first for exact field names. Use kind 'computation' for math (statistics, financial, vector/matrix, simulation) over arrays: never paste large data into args — use bindings to pull columns from connected sources. Simulation modules require a seed. Large results are truncated for context; the full result stays retrievable — pass the returned result_id to the getResult tool. Execution requires a free community login (`sqai login` device registration, or SQAI_API_KEY) — fully offline thereafter.

### `explainQuery` (~107 tokens)

Dry-run a queryData request without executing it. kind 'query': resolve and verify the plan (resolved_plan, plan steps, plan_hash, confidence, validated). kind 'computation': check the capability exists and get its exact signature, a preview invocation_hash, and whether a seed is required. Use this to debug clarifications and rejections before running queryData. Execution requires a free community login (`sqai login` device registration, or SQAI_API_KEY) — fully offline thereafter.

### `getResult` (~175 tokens)

Fetch the full stored result of an earlier queryData call by its result_id. Use it when queryData returned truncated: true — the preview is capped for context, this returns every stored row/element (only results within the output-size cap, 10 MB by default, get a result_id at all). The store is in-memory and short-lived: default 15-minute TTL, evicted oldest-first under memory pressure. An unknown, expired, or evicted result_id returns a structured result_not_found error — re-run the original queryData request to regenerate. Read-only and idempotent; takes no other parameters. Execution requires a free community login (`sqai login` device registration, or SQAI_API_KEY) — fully offline thereafter.

Input parameters:

- `result_id` (string, required): The result_id from a queryData ok result.

## Common questions

### What is the SQAI — deterministic, read-only structured data MCP server?

SQAI — deterministic, read-only structured data is an MCP server listed in the public MCP registry as io.github.thyn-ai/sqai. SQAI MCP server, four governed, deterministic, read-only data tools. Free login to execute. This page covers its npm package (@thyn-ai/sqai-mcp).

### Is the SQAI — deterministic, read-only structured data MCP server safe to use?

SQAI — deterministic, read-only structured data scores 70 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 25 September 2026. It declares no install or post-install scripts. 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 SQAI — deterministic, read-only structured data MCP server expose?

SQAI — deterministic, read-only structured data exposes 4 tools: listSources, queryData, explainQuery, getResult. Their descriptions and schemas cost roughly 551 tokens of context every time the server is loaded.

### Is the SQAI — deterministic, read-only structured data MCP server still maintained?

SQAI — deterministic, read-only structured data is still listed as active in the MCP registry. We last reached this channel on 25 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the SQAI — deterministic, read-only structured data MCP server under?

SQAI — deterministic, read-only structured data declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
