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
- 39 of 120 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency19
- Repository check failed: the declared repository URL returned HTTP 404. See how to fix → View diagnostics → Fail
- 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 11 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability74
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 249 tokens (~249/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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 1 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
Unverified: 1 category
A category scored 0 because we could not verify it: 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.

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 →
search_agent_configs Search real AGENTS.md / CLAUDE.md files from public repositories ~249
Search RuleStack, an index of real agent instruction files (AGENTS.md, CLAUDE.md, Cursor rules, Copilot instructions, Windsurf, GEMINI.md, Cline) harvested from public GitHub repositories and scored for quality. Use when writing or reviewing an agent config and you want to see how well-maintained projects with a given stack actually write theirs — "show me CLAUDE.md files from Next.js repos", "what do good AGENTS.md files put in their build section".
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | – | Comma-separated format slugs: agents-md, claude-md, cursor-rules, copilot-instructions, windsurf-rules, gemini-md, cline-rules. |
| limit | number | – | How many to return, 1-10. Default 5. |
| min_quality | number | – | Minimum quality score, 0-100. |
| stack | string | – | Comma-separated stack slugs, ANDed. e.g. "nextjs,typescript". |
| tag | string | – | Comma-separated section tags, ANDed: build, test, security, code-style, architecture, git-pr, do-not, docs. |
