## 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**: 86/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (94 of 98), 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 (94 of 98), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 84/100

  - Actively maintained (last published 2 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 679 tokens (~67/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 74, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (10)

### `x402_working_services` (~60 tokens)

List live x402 services

List x402 agent-payment services that are currently ALIVE and return a valid x402 challenge, ranked by trust score. About 85% of x402 endpoints are dead or invalid — use this to avoid paying broken or scam endpoints. Free.

### `check_x402_endpoint` (~75 tokens)

Check an x402 endpoint before paying

Before paying an unknown x402 endpoint, check whether it is live and returns a valid x402 payment challenge. Returns liveness, price, network and a pay/avoid verdict. For full uptime + reputation, use PulseFeed's paid /trust API.

Input parameters:

- `url` (string, required): The x402 endpoint URL to verify

### `pulsefeed_products` (~57 tokens)

PulseFeed products and pricing

List PulseFeed's paid x402 products — real-time Base on-chain intelligence for AI agents: token pulse, whale alerts, smart-money accumulation/distribution, momentum, and the x402 trust oracle — and how to pay via x402.

### `x402_ecosystem_stats` (~68 tokens)

x402 ecosystem health stats

Live health of the entire x402 agent-payment ecosystem: how many endpoints are tracked/alive/dead, catalog accuracy audit (what share of 'healthy' listings actually work), scam-risk distribution and receiver-stability breakdown. Compact aggregates from PulseFeed's continuous independent audit. Free.

### `x402_leaderboard` (~55 tokens)

x402 trust leaderboard

Top x402 services ranked by PulseFeed Trust Score (0-100, open standard): the most reliable live agent-payment endpoints right now, with price and network. Use to pick a trustworthy service to pay. Free.

### `x402_incidents` (~65 tokens)

Live x402 security incidents

Live security incidents in the x402 economy caught by PulseFeed's detector: receiver hijacks (payTo swapped), bait-and-switch pricing, honeypots, unverified receivers, price gouging — each with an on-chain proof URL. Check before paying anything. Free.

### `x402_changes` (~68 tokens)

Recent x402 ecosystem changes

What changed in the x402 ecosystem in the last 7 days: services that went dark, receiver (payTo) swaps — possible hijacks, price changes, recovered and newly-seen services. Derived from PulseFeed's compounding time-series (cannot be reconstructed after the fact). Free.

### `mcp_security_report` (~68 tokens)

State of MCP security

State of MCP Security: how many audited MCP servers run an arbitrary install script on npm i, are abandoned, ship no repository or license — with day-over-day deltas and a sample of currently-flagged servers. From PulseFeed's daily MCP audit (950+ servers). Free.

### `mcp_check_server` (~83 tokens)

Audit an MCP server before installing

Before installing an MCP server, audit it by npm package name: does it run an install script (arbitrary code at npm i), is it abandoned, does it ship a repository/license, weekly downloads, provenance — verdict safe/caution/avoid. Free.

Input parameters:

- `package` (string, required): npm package name of the MCP server, e.g. @scope/name

### `x402_data_sample` (~80 tokens)

Free sample of the trust dataset

FREE sample of the PulseFeed Data API: top-10 live x402 services as FULL records (compounding payTo/price history, scam flags, on-chain receiver profile), top-10 MCP servers with full audit profile, and 3 live incidents. The full cross-domain dataset is GET /data/full ($1 via x402). Free.
