Using Cline to Access TAU Token Endpoints via MCP

Prerequisites

• Cline⁠ installed.
• An API key or JWT from TAU Studio⁠ or TAU Market.
• npx⁠ or bunx⁠ installed and available in your path.
• The @pinax/mcp package requires Node 18+, as it relies on built-in fetch() / Headers, which are not available in Node 17 or older. You may need to specify an exact path to an up-to-date Node version, or uninstall previous versions of Node to ensure @pinax/mcp uses the correct version.

Configuration

Create or edit your cline_mcp_settings.json file.

1{2  "mcpServers": {3    "tau-token": {4      "command": "npx",5      "args": ["@pinax/mcp", "--sse-url", "https://token.mcp.tau.org/sse"],6      "env": {7        "ACCESS_TOKEN": "<TAU API Key or JWT>"8      }9    }10  }11}

Troubleshooting

To enable logs for the MCP, use the --verbose true option.

ENOENT

Try to use the full path of the command instead:

• Run which npx or which bunx to get the path of the command.
• Replace npx or bunx in the configuration file with the full path (e.g. /home/user/bin/bunx).

Server disconnected

Double-check your TAU API key. Otherwise, verify that https://token.mcp.tau.org/sse⁠ is reachable from your network.
