                AI Suite > Token API MCP

                Using Claude Desktop to Access the Token API via MCP

                Prerequisites

                • Claude Desktop⁠ installed.
                • A JWT token from The Graph 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

                1{2  "mcpServers": {3    "token-api": {4      "command": "npx",5      "args": ["@pinax/mcp", "--sse-url", "https://token-api.mcp.thegraph.com/sse"],6      "env": {7        "ACCESS_TOKEN": "<https://thegraph.market JWT Access Token>"8      }9    }10  }11}

                Troubleshooting

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

                ENOENT

                Error dialog in Claude Desktop showing 'ENOENT' system error, indicating the npx/bunx command wasn't found in the system path.

                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

                Connection error notification in Claude Desktop displaying 'Server disconnected' message.

                Double-check your API key otherwise look in your navigator if https://token-api.mcp.thegraph.com/sse is reachable.

                You can always have a look at the full logs under Claude/logs/mcp.log and Claude/logs/mcp-server-pinax.log for more details.
