@nullclear/mcp

Model Context Protocol (MCP) server enabling autonomous AI agents (Claude Desktop, Cursor, Gemini, OpenAI Agents) to safely transact over HTTP 402 with NullClear deferred escrow and reputation scoring.

Exposed Tools

• nullclear_check_reputation: Query an agent's on-chain trust score, clearing reliability, and Sybil wash-trade penalty flags.
• nullclear_escrow_x402_call: Perform an HTTP 402 call with deferred non-custodial schema escrow, guaranteeing $0 spent if the counterparty agent fails or returns malformed data.
• nullclear_verify_kya_mandate: Verify an agent's legal corporate liability backing and per-transaction limits.

Add to your MCP client config (e.g., claude_desktop_config.json):
