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. How we score → Why this is hard to score →
Supply Chain Security50
- Malware scan not yet available for this package.Unverified
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency74
- Repository check failed: the declared repository URL redirects; it must resolve directly. See how to fix → View diagnostics → Fail
- Cryptographically verified build provenance (signed, bound to Wangggym/quarry). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 0 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability72
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 349 tokens (~58/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management97
- Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 13% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "exec_sql" implies "exec" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 4 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
describe_table ~40
Column names, types and nullability for one table.
| Name | Type | Req | Description |
|---|---|---|---|
| db | string | yes | – |
| env | string | – | – |
| table | string | yes | – |
No output schema declared.
No examples provided.
exec_sql ~134
Execute SQL (or a redis command) against a database and get a structured result {columns, rows, rowCount, truncated, elapsedMs}. READ-ONLY by default: writes/DDL fail with code 8 unless you pass write=true AND the server was started with --write; a prod env additionally requires confirm_prod=true. SELECTs without LIMIT get an automatic LIMIT (max_rows, default 500).
| Name | Type | Req | Description |
|---|---|---|---|
| confirm_prod | boolean | – | – |
| db | string | yes | – |
| env | string | – | – |

| write | boolean | – | – |
No output schema declared.
No examples provided.
list_connections ~43
List all configured database connections, grouped into project folders and env-sets (same logical db across dev/prod/...). Start here to learn which `db` keys exist.
Input schema present but exposes no named parameters.
No output schema declared.

list_saved_queries ~24
List the workspace's saved named queries (name, target db, params).
Input schema present but exposes no named parameters.
No output schema declared.

list_tables ~52
List tables of a database (or keys for a redis connection).
