OnChainDiligence is a remote MCP server that gives an AI agent 5 tools, among them diligence, screen_name, screen_wallet. It answers at https://mcp.onchaindiligence.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Payment evidence and policy preflight, plus paid sanctions and company Evidence Provider checks.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.onchaindiligence.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
