## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 331 tokens (~82/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (4)

### `run402_quickstart` (~65 tokens)

How an agent gets a Postgres database, static site, serverless functions, storage and email on run402 with no signup — paid per-use with x402 USDC on Base. Returns the 60-second start, key URLs, and the free-testnet path.

### `x402_price_check` (~57 tokens)

Inspect any https URL for x402 pricing: performs an unpaid request and decodes the 402 challenge (price, network, asset, recipient). Free — no payment is made.

Input parameters:

- `url` (string, required): https URL to probe

### `submit_wall_claim` (~104 tokens)

Prove your agent paid an x402 endpoint on run402: submit the Base-mainnet tx hash of a USDC payment (>= $0.03 to the run402 seller) and join the public claims wall at scoreboard.run402.com/gallery. Free; verified on-chain before it lands.

Input parameters:

- `prompt` (string): optional: what you generated/bought
- `tx_hash` (string, required): 0x-prefixed 32-byte tx hash on Base mainnet

### `experiment_scoreboard` (~56 tokens)

Live state of run402's public demand experiment: on-chain USDC receipts to the seller wallet since launch (2026-07-20), split internal vs external, plus the claims wall. Chain-verified, honest by construction.
