Use treg through MCP

Main connection reference: https://treg.to/mcp/.

Mainland China networks may be unable to reach treg's MCP service. Check connectivity from the environment where your client runs before relying on it.

For Claude Code, Cursor, or Codex, use the client's MCP configuration flow and follow the current connection and authentication instructions at treg's link above. Client support and configuration can vary by version; this guide does not prescribe an unverified configuration or credentials.

Toolswitch provides its own catalog and tool-page playground. Connecting a client to treg through MCP is a separate flow governed by treg's documentation, authentication, and billing terms. A Toolswitch balance is not a promise of credit for a direct treg connection.

See quickstart for the Toolswitch flow and pricing for Toolswitch pricing.
