Available components
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 Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 35 of 104 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 82 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability87
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 211 tokens (~52/item across 4 items; 2 tools + 2 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management93
- Stability observed for 28 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (50% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 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

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 →
analyze_migration Analyze a SQL migration for locking hazards ~112
Lint a PostgreSQL migration for operations that take dangerous locks (table rewrites, blocking index builds, validating constraints, destructive/breaking changes) and return a PASS/REVIEW/BLOCK verdict with per-statement findings and safe rewrites. Call this before applying or approving any migration.
| Name | Type | Req | Description |
|---|---|---|---|
| assumeLargeTables | boolean | – | Assume target tables are large/hot, so scans and rewrites are flagged. Default true (fail safe). |
| sql | string | yes | The full SQL migration script to analyze. |
| Name | Type | Req | Description |
|---|---|---|---|
| findings | array | yes | – |
| stats | object | yes | – |
| summary | string | yes | – |
| verdict | string | yes | – |
No examples provided.
explain_lock Explain a PostgreSQL lock mode ~66
Given a lock mode name (e.g. 'ACCESS EXCLUSIVE') or a fragment of an operation, explain what it blocks and which operations acquire it.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | A lock mode name or operation fragment, e.g. 'ACCESS EXCLUSIVE' or 'create index'. |
