## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 85
- drivers: +repository +dns-namespace +website +reachable +uptime-100% +updated-25d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 74/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: run402_quickstart (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); x402_price_check (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 156 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 50 (weight 15)

- warn `deps.known_vulns`: 2 advisories of lower severity or without a published fix: GHSA-727h-3vm5-qwq6 in mppx@0.4.12 (direct, fixed in 0.8.2), GHSA-vc9j-9wph-qghj in mppx@0.4.12 (direct, fixed in 0.8.2)
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: run402-mcp@4.104.2 resolved: 160 packages

- tools: 2, about 156 tokens to load them all
- tool set hash: 26f54502885cd8395cf4936b22e887dc
- tools last changed: 2026-10-11T14:49:42.160Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.run402/mcp.svg)](https://protogrid.dev/servers/com.run402/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-11 `experiment_scoreboard` removed
  - 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.
- 2026-10-11 `submit_wall_claim` removed
  - 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.

## Tools (2)

- `run402_quickstart`: 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`: 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.
