Overview

AI-generated overview

A local MCP server that lets an assistant read Lighter perpetual markets and place guarded orders, including the H100 compute-price market.

What you can do
Read Lighter perpetual market data, including the H100 compute-price market, and observe account state, optionally with a read-only token instead of a signing key. Place orders on the account, with each order signed against the configured chain and capped by a per-order notional ceiling. Choose the deployment to read (mainnet, testnet or robinhood) and the sub-account to trade from.
When to use it
Use it when you want an assistant to monitor Lighter perpetual markets or account positions and, where intended, submit orders under a hard per-order USD limit. Read-only observation is possible without a signing key.
Requirements
Runs locally over stdio from the npm package lighter-mcp, so Node.js is needed. Configuration is by environment variables: LIGHTER_NETWORK (defaults to mainnet), LIGHTER_ACCOUNT_INDEX, LIGHTER_API_KEY_INDEX, LIGHTER_MAX_NOTIONAL_USD, optionally LIGHTER_CHAIN_ID, and either LIGHTER_API_KEY_PRIVATE_KEY or LIGHTER_READ_ONLY_TOKEN. Network access to the chosen deployment is required.
Before you install
LIGHTER_API_KEY_PRIVATE_KEY is a secret granting full write authority over the account it is bound to, so use a dedicated sub-account and keep the key out of shared logs. Orders move real funds; LIGHTER_MAX_NOTIONAL_USD is required before any order can be signed, so set it deliberately. LIGHTER_CHAIN_ID is bound into every signature, and a wrong value can produce invalid or misdirected orders. Prefer LIGHTER_READ_ONLY_TOKEN when only observation is needed.

Installation

In SourceWeft

  1. Open Lighter Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
