Check before you pay.\n\nThree tools for any MCP-compatible agent (Claude Desktop, Cursor, Windsurf, etc.):\n\n| Tool | Price | What it does |\n|------|-------|-------------|\n| `trust_check` | $1 USDC | Quick trust evaluation: reachability, x402 compliance, governance, LLM analysis. Returns score 0-100 and PROCEED/CAUTION/DO NOT TRANSACT. |\n| `integrity_report` | $25 USDC | Premium multi-model dossier: 3 LLMs evaluate independently. Composite integrity score, threat vectors, executive summary, risk grade A+ through F. |\n| `search_bazaar` | Free | Search the Coinbase x402 Bazaar for services by keyword. |\n\n## Install\n\n```json\n{\n  \"mcpServers\": {\n    \"crest-trust-gate\": {\n      \"command\": \"npx\",\n      \"args\": [\"@crestdeploymentsystems/mcp-trust-gate\"]\n    }\n  }\n}\n```\n\nOr run directly:\n\n```bash\nnpx @crestdeploymentsystems/mcp-trust-gate\n```\n\n## Payment\n\nBase mainnet USDC via x402 protocol. No API keys. No subscriptions.
