npx -y verifox-mcp
Configure / authenticate
MCP100 setup guide
Set VERIFOX_API_KEY for authenticated API. Alternatively publisher HTTP mode supports POST /mcp with GET /health; do not invent host/port.
Use correct transport and published host config. Never paste secrets in chat; server registration is separate from software installation.
Check connection
Suggested check
Use GET /health in HTTP mode; confirm tool list in stdio mode.
Remove / uninstall / revoke
MCP100 setup guide
If registered as `verifox-mcp` in Claude Code, remove its exact client entry with `claude mcp remove verifox-mcp`; for Cursor/Claude Desktop/Codex, remove the matching MCP entry in that host settings. This client removal is MCP100-composed, not a vendor uninstall instruction. Npx does not imply a global install; do not delete user data or revoke credentials implicitly.
