claude mcp add lighter-mcp -e 'LIGHTER_NETWORK=mainnet' -e 'LIGHTER_ACCOUNT_INDEX=<LIGHTER_ACCOUNT_INDEX>' -e 'LIGHTER_API_KEY_INDEX=<LIGHTER_API_KEY_INDEX>' -e 'LIGHTER_API_KEY_PRIVATE_KEY=<your lighter_api_key_private_key>' -e 'LIGHTER_MAX_NOTIONAL_USD=<LIGHTER_MAX_NOTIONAL_USD>' -e 'LIGHTER_CHAIN_ID=<LIGHTER_CHAIN_ID>' -e 'LIGHTER_READ_ONLY_TOKEN=<your lighter_read_only_token>' -- npx -y lighter-mcp@0.1.1

Environment variables

  • LIGHTER_NETWORK Deployment to read: mainnet, testnet, or robinhood. Defaults to mainnet.
  • LIGHTER_ACCOUNT_INDEX Sub-account the agent trades from. Read-only tools work without it.
  • LIGHTER_API_KEY_INDEX API key slot bound to the sub-account, 0 to 254.
  • LIGHTER_API_KEY_PRIVATE_KEY secret API key private key. Full write authority over the account it is bound to, so use a dedicated sub-account.
  • LIGHTER_MAX_NOTIONAL_USD Per-order notional ceiling in USD. Required before any order can be signed.
  • LIGHTER_CHAIN_ID Layer-2 chain id bound into every signature. Mainnet uses 304 and testnet 300, so this is only needed on a deployment that publishes none.
  • LIGHTER_READ_ONLY_TOKEN secret Read-only token for account observation without a signing key.
