## MCP tools (9)

### `lighter_markets` (~111 tokens)

List Lighter markets

List or search the perpetual markets on a Lighter deployment. Mainnet lists id 182, H100, a perpetual on the rental cost of an NVIDIA H100, which the response always includes. Results are capped and the response reports the full count, so pass a query to narrow the list.

Input parameters:

- `limit` (integer): Maximum markets to return, 1 to 100.
- `query` (string): Case-insensitive substring match on the ticker, for example "H100" or "SOL".

### `lighter_market` (~96 tokens)

Lighter market detail

Mark price, index price, funding rate, and top of book for one market. Select the market by market_id or by symbol.

Input parameters:

- `depth` (integer): Order book levels per side, 1 to 20.
- `market_id` (integer): Market id, for example 182 for H100. Use this or symbol.
- `symbol` (string): Market ticker, for example H100. Use this or market_id.

### `lighter_h100` (~116 tokens)

H100 compute price

Price, funding, and book depth for market 182 (H100), a perpetual on the rental cost of an NVIDIA H100. Use it to read the traded cost of compute and to see which side funding pays before hedging a GPU bill. The H100 book is thin: about $7,100 of 24 hour volume, open interest near $10,000, and 4.00 of size at the top of book on each side when measured on 2026-08-26. Size hedges accordingly.

### `lighter_funding` (~168 tokens)

Lighter funding rates

Current funding rates and settled funding history. The current rate is a fraction charged over one 8 hour period, and settled history is an hourly percent, so each number carries its unit in the response. A positive rate means longs pay shorts. Omit both selectors to rank Lighter's own markets by the largest rate. Rates from the other venues Lighter tracks are reference data and are left out, since a position opened here collects Lighter's rate.

Input parameters:

- `history_limit` (integer): Settled hourly funding payments to return for the selected market, 0 to 50.
- `market_id` (integer): Market id, for example 182 for H100. Use this or symbol.
- `symbol` (string): Market ticker, for example H100. Use this or market_id.

### `lighter_account` (~129 tokens)

Lighter account state

Collateral, open positions, and account value for one Lighter sub-account. Defaults to the account in LIGHTER_ACCOUNT_INDEX. Pass a market selector to include the resting orders on that market. Order listing needs either a read-only token or a signing key, since Lighter authenticates that route.

Input parameters:

- `account_index` (integer): Sub-account to read. Defaults to the configured account.
- `market_id` (integer): Market id, for example 182 for H100. Use this or symbol.
- `symbol` (string): Market ticker, for example H100. Use this or market_id.

### `lighter_place_order` (~349 tokens)

Place a Lighter order

Sign and send one limit or market order. max_notional_usd is required and has no default. The order is priced against one book snapshot and refused above the ceiling before it is signed, so the order that goes out is the order that was checked. The server applies its own configured ceiling as well, and the lower of the two wins. A Lighter API key is full write authority over the account it is bound to, so run this server against a dedicated sub-account funded with only what the agent may lose.

Input parameters:

- `market_id` (integer): Market id, for example 182 for H100. Use this or symbol.
- `max_notional_usd` (number, required): Required ceiling on order notional in USD. The order is refused when its worst-case notional exceeds this value. There is no default.
- `order_type` (string): limit rests on the book. market is immediate-or-cancel with an average execution bound.
- `price` (number): Limit price in quote units. Required for a limit order.
- `reduce_only` (boolean): Refuse to open or increase a position. A reduce-only order can only shrink an existing position, so it is exempt from max_notional_usd and from the market size floor.
- `side` (string, required): Order side.
- `size` (number, required): Order size in base units, in human decimals.
- `slippage_bps` (number): Average execution bound for a market order, in basis points.
- `symbol` (string): Market ticker, for example H100. Use this or market_id.
- `time_in_force` (string): Resting behaviour for a limit order. Defaults to gtt.

### `lighter_cancel` (~108 tokens)

Cancel a Lighter order

Cancel one resting order by market and order index. Read the order index from lighter_account with a market selector.

Input parameters:

- `market_id` (integer): Market id, for example 182 for H100. Use this or symbol.
- `order_index` (string, required): Exchange-assigned order index, as a decimal string. It exceeds the safe integer range, so pass it exactly as lighter_account reported it.
- `symbol` (string): Market ticker, for example H100. Use this or market_id.

### `lighter_cancel_all` (~44 tokens)

Cancel all Lighter orders

Cancel every resting order on the configured sub-account, across all markets. Lighter cancels account-wide, so this cannot be scoped to one market. Open positions are untouched.

### `lighter_hedge_h100` (~260 tokens)

Hedge H100 compute cost

Size a hedge on market 182 (H100) for a number of GPU hours, price it against the live book, and report the funding it earns or pays. A short covers a renter against rising compute prices. This tool is a dry run and returns a plan. It signs and sends the order only when execute is true, and max_notional_usd is required either way. A Lighter API key is full write authority over the account it is bound to, so run this server against a dedicated sub-account funded with only what the agent may lose.

Input parameters:

- `execute` (boolean): Set true to sign and send the hedge. Left false, the tool returns the plan and sends nothing.
- `gpu_hours` (number, required): H100 hours of rental cost to cover. One unit of base is one GPU hour.
- `max_notional_usd` (number, required): Required ceiling on order notional in USD. The order is refused when its worst-case notional exceeds this value. There is no default.
- `side` (string): short covers a buyer of compute against rising prices. long covers a seller of compute against falling prices.
- `slippage_bps` (number): Average execution bound in basis points from the touch.

## Common questions

### What is the io.github.winter0x/lighter-mcp server?

io.github.winter0x/lighter-mcp is listed in the public MCP registry as io.github.winter0x/lighter-mcp. Read Lighter perpetual markets and place guarded orders, including the H100 compute-price market. This page covers its npm package (lighter-mcp).

### Is the io.github.winter0x/lighter-mcp server safe to use?

io.github.winter0x/lighter-mcp scores 76 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.winter0x/lighter-mcp server expose?

io.github.winter0x/lighter-mcp exposes 9 tools: lighter_markets, lighter_market, lighter_h100, lighter_funding, lighter_account, and 4 more. Their descriptions and schemas cost roughly 1,381 tokens of context every time the server is loaded.

### Is the io.github.winter0x/lighter-mcp server still maintained?

io.github.winter0x/lighter-mcp is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the io.github.winter0x/lighter-mcp server under?

io.github.winter0x/lighter-mcp declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
