Use with Claude

To use this MCP server with Claude, add it to your MCP configuration file:

For the VSCode Claude extension:

{
  "mcpServers": {
    "polygon": {
      "command": "node",
      "args": ["/path/to/polygon-mcp/build/index.js"],
      "env": {
        "SEED_PHRASE": "Your 12-word seed phrase"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

For the Claude desktop application:

{
  "mcpServers": {
    "polygon": {
      "command": "node",
      "args": ["/path/to/polygon-mcp/build/index.js"],
      "env": {
        "SEED_PHRASE": "Your 12-word seed phrase"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}
