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 →
Supply Chain Security0

Provenance & Transparency32
- 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
- License check failed: no license is declared. See how to fix → Fail
- Actively maintained (last published 13 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability63
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 387 tokens (~387/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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 (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 2 categories
Categories scored 0 because we could not verify them: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

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.
exec ~387
Execute Python code in a network-isolated sandbox and return its output. Environment: Python 3 with stdlib plus PyYAML and Jinja2. Limits: no network; wall-clock timeout defaults to 30s (max 300s); combined stdout+stderr is capped at 1048576 bytes then truncated; stdin is capped at 1048576 bytes. A non-zero exit_code or timed_out=true is a NORMAL result, not a tool error. INPUT CONTRACT — follow exactly: • `code`: Python source as a single string, newlines as \n. Top-level statements MUST start at column 0 — NO leading spaces/tabs. Indent ONLY bodies of blocks (after a line ending with ':'). Wrong: "import json\n d=json.load(...)" (leading space → IndentationError). Right: "import json\nd=json.load(...)". • `stdin`: a STRING piped to the program's stdin (read it with sys.stdin). To pass JSON, pass it AS a string — do not pass a parsed object/map. • Read input from sys.stdin, print results to stdout. Example: code="import json,sys\nd=json.load(sys.stdin)\nprint(len(d['items']))", stdin="{\"items\":[1,2,3]}" → stdout "3".

| stdin | string | — | STRING piped to the program's stdin (max 1 MiB). To pass JSON, pass it as a string — not a parsed object. |
| timeout_s | integer | — | wall-clock timeout in seconds (default 30, clamped to [1,300]) |
