## 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 2026-10-17.

- **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.
  - 39 of 120 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 19/100
  - Repository check failed: the declared repository URL returned HTTP 404.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 11 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (excellent).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 1 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.

**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.

## MCP tools (1)

### `search_agent_configs` (~249 tokens)

Search real AGENTS.md / CLAUDE.md files from public repositories

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".

Input parameters:

- `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.
