## Connection (mcpServers)

```json
{
  "mcpServers": {
    "preflight": {

      "url": "https://preflight--preflight-api-mcp.modal.run/mcp"
    }

## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% +updated-0d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 81/100 (new)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 75 (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: preflight_sim (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); preflight_token_risk (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); preflight_pricing (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 415 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

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

- n/a `stability.changes`, `stability.rug_pull`, `stability.new_links`: tool history recorded for 0 of the 7 days needed

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

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 415 tokens to load them all
- tool set hash: 1b20815aee99075a96a55562394d29ac
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.dainidude/preflight.svg)](https://protogrid.dev/servers/io.github.dainidude/preflight)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `preflight_check`: Scan Solidity source and return a security verdict. This is a paid call ($0.01 USDC on Base mainnet) that flows through x402; in dev mode (DEV_MODE=1) no payment is required.
- `preflight_pricing`: Return the Preflight service info and price list (free).
- `preflight_sim`: Simulate a transaction against a contract and return revert reason, gas used, balance deltas, and severity-scored findings. mode='quick' costs $0.05 (eth_call); mode='deep' costs $0.25 (anvil local fork with gas, balance_delta_wei, and internal_calls). Paid in USDC on Base mainnet via x402; DEV_MODE=1 skips payment.
- `preflight_token_risk`: Check a token contract before trading it. Returns a honeypot transfer verdict, transfer tax percentage, and owner privileges as a severity-scored ScanReport. Paid call ($0.05 USDC on Base mainnet) via x402; DEV_MODE=1 skips payment.
