About
Trust + receipt layer for x402 agents on Solana: free preflight + paid signed V6 trust receipt.
Security Report
5.2
Moderate5.2Moderate RiskThis is a legitimate Solana x402 payment MCP server for TWZRD's trust intelligence API. The codebase demonstrates solid architectural security with proper payment guardrails, input validation, and use of official SDK libraries. However, there are several moderate concerns: secret key handling in environment variables without clear rotation guidance, missing rate limiting on free endpoints, and some input validation gaps in helper functions that could allow malformed data to reach the API. Package verification found 1 issue (1 critical, 0 high severity).

TWZRD Agent Intel
Live MCP server • https://intel.twzrd.xyz/mcp (18 tools)
Client SDKs • x402 trust gates + Eliza plugins
Self-host • Deploy configs + public wiring (scoring engine stays private)
Check any Solana wallet or x402 seller before you pay. Free preflight returns a ReadinessCard (allow / warn / block + trust score + risk factors) from the real cross-facilitator Solana x402 payment corpus.
Quick Start
# No signup, no API key — just curl
curl -s -X POST https://intel.twzrd.xyz/v1/intel/preflight \
-H 'content-type: application/json' \
-d '{"seller_wallet": "6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P", "agent_intent": "test"}'
Read decision: block → don't pay. warn → cautious. allow → proceed.
