Overview

AI-generated overview

Lets an assistant fetch one live row of Lighter perpetuals market data: symbol, mark price, 24h change and 24h volume.

What you can do
The server exposes a single tool, get_market_preview, which returns one live row from Lighter's perpetuals markets covering symbol, mark price, 24-hour change percentage and 24-hour volume in USD. It reads Lighter's public API live and is described as free with no account required. The fuller funding-rate and cross-exchange spread snapshot is a separate paid HTTP route and is not available through this MCP server.
When to use it
Useful when an assistant needs a quick, current quote or volume figure for a Lighter perpetuals market without setting up an account. It is not the right choice if you need funding rates, spread comparisons or multi-market snapshots, since those are outside the MCP tool.
Requirements
A remote streamable HTTP endpoint; nothing to install locally. No authentication, environment variables or headers are declared. Network access to the remote endpoint and to Lighter's public API is implied.
Before you install
The server is free and read-only, but the paid funding and spread data is served by a separate HTTP route outside MCP, so expect a payment step if you need it. Market data comes from a third-party public API and should not be treated as authoritative for trading decisions.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.workers.sebastiaan-ba3.signals%2Ftools/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

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.
