Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
LIGHTER_NETWORKOptional | Deployment to read: mainnet, testnet, or robinhood. Defaults to mainnet. |
LIGHTER_ACCOUNT_INDEXOptional | Sub-account the agent trades from. Read-only tools work without it. |
LIGHTER_API_KEY_INDEXOptional | API key slot bound to the sub-account, 0 to 254. |
LIGHTER_API_KEY_PRIVATE_KEYOptional, secret | API key private key. Full write authority over the account it is bound to, so use a dedicated sub-account. |
LIGHTER_MAX_NOTIONAL_USDOptional | Per-order notional ceiling in USD. Required before any order can be signed. |
LIGHTER_CHAIN_IDOptional | 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_TOKENOptional, secret | Read-only token for account observation without a signing key. |
