MCP Integrations — use Attestr in your AI tools

  • Add Attestr to Claude's MCP server config
  • Ask "Attestr this vault: HLP"
  • Claude calls the tool and shows you the result

Wire Attestr as an MCP tool in Claude Code CLI. Run risk checks without leaving your terminal — results stream back inline.

  • Add server config to .claude/mcp.json
  • Use in Claude Code with /mcp or tool call
  • Results appear in your session context

Attestr appears as a tool in Cursor AI sessions. Ask Cursor to check a contract address before you integrate it into your code.

  • Open Settings → Features → MCP
  • Add Attestr server URL and key
