## 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 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to TateLyman/x402-triage-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 75 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 78/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 341 tokens (~85/item across 4 items; 3 tools + 1 resources), lean.
  - 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.
- **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.

First indexed and scored.

## MCP tools (3)

### `triage_x402_surface` (~163 tokens)

Triage x402 payment surface

Run a no-payment external pass against one public x402, MPP, Pay.sh, OpenAPI, manifest, or HTTP 402 endpoint. The tool calls the Tate Programs public triage API and returns status, payment headers, parsed challenge shape, attack-class checks, cache/CORS notes, and paid review handoff. It does not send X-PAYMENT, wallet signatures, API keys, private tokens, or paid calls.

Input parameters:

- `method` (string): No-payment probe method. Use POST only for endpoints that intentionally expose a public paid POST route.
- `origin` (string): Optional browser Origin for CORS/payment-header readability checks.
- `url` (string, required): Public HTTPS manifest, OpenAPI file, paid endpoint, or discovery URL to review.

### `watch_402_index` (~127 tokens)

Watch 402 Index listings

Look up public 402 Index service records by provider, domain, endpoint URL, or search term. Use this before listing, outreach, launch review, or re-check work to spot down services, invalid payment requirements, and unverified domains. This is public metadata only and does not send payment headers or paid calls.

Input parameters:

- `health` (string): Optional health filter.
- `limit` (number): Maximum records to return.
- `protocol` (string): Protocol filter.
- `q` (string, required): 402 Index search term, provider name, domain, service URL, or endpoint URL.

### `x402_paid_paths` (~35 tokens)

Return x402 paid API paths

Return the Tate Programs paid x402 API endpoints, service catalog, AgentCard, and fixed-scope review handoff URLs.
