What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs in the cloud
Transport: Streamable HTTP
Category: Accounting, finance & tax
You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http skylit https://mcp.skylit.ai/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

    "skylit": {
      "url": "https://mcp.skylit.ai/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Skylit safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 37 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Skylit MCP

Skylit is the data intelligence platform for AI trading: options flow, volatility, dealer positioning and dark pool data for US markets. The Skylit MCP server gives any MCP client (Claude, ChatGPT, Cursor, VS Code, Gemini CLI, Codex and others) read-only tools over that data.

This repository holds setup guides for each client, the Claude Code plugin, a Gemini CLI extension, an agent skill, and runnable examples. It contains no server code; the server is hosted by Skylit.

Status: beta. The API and MCP server are open to Skylit members with API

access. Check yours on the Developer page.

Quick connect


URL	`https://mcp.skylit.ai/mcp`
Transport	Streamable HTTP
Auth	Sign in with Skylit (OAuth): add the URL and approve on the Skylit page. Or send `Authorization: Bearer` with a key from the Developer page.

Claude Code:

claude mcp add --transport http skylit https://mcp.skylit.ai/mcp

then /mcp -> skylit -> Authenticate

Cursor, LM Studio, Warp and other clients that use an mcpServers JSON file:

"mcpServers": { "skylit": { "url": "https://mcp.skylit.ai/mcp", "headers": { "Authorization": "Bearer YOUR_SKYLIT_API_KEY" } } } }

Leave out headers to sign in with Skylit instead. Field names differ between clients (url, httpUrl, serverUrl, servers), so check your client below.

Then ask: *"What are the key gamma levels and today's flow tone for SPY?"*

Python

pip install skylit

from skylit import Skylit

Skylit().gex_levels("SPY") # reads SKYLIT_API_KEY

Source and docs: packages/python.

TypeScript

npm install @skylitai/sdk

import { Skylit } from "@skylitai/sdk";

await new Skylit().gexLevels("SPY"); // reads SKYLIT_API_KEY

Source and docs: packages/typescript.

Staying current

This repo is checked against the live API every 6 hours (scripts/sync.py, sync workflow): the tool catalog and REST specs in reference/ are refreshed from Skylit's published docs, and any guide, skill, example or SDK that names a tool or endpoint that no longer exists fails the check and opens an issue.

Intelligence toolset

One-call answers for agents, each with a short factual summary, compact data and meta (cost, balance, asOf, partial). They have their own tool list, so an agent loads only these:

https://mcp.skylit.ai/mcp?toolset=intelligence

Tool	Answers	Credits
`explain_levels`	Key dealer-positioning levels for a symbol	1
`vol_context`	Implied volatility, IV rank, expected moves, scheduled events	2
`whats_changed`	How the positioning board moved since a given time	6
`market_brief`	VIX complex, market-wide options flow, SPX and QQQ levels	5
`flow_context`	Today's options flow read for a ticker	9

Details: Intelligence tools.

Tools

69 tools, all read-only. Most wrap one Skylit REST endpoint with the same credit cost; the intelligence tools combine several and are served on their own list (/mcp?toolset=intelligence). Full catalog with arguments and prices: www.skylit.ai/docs/mcp/tools; machine-readable copy: reference/tools.json.

Account	`account_usage`
Intelligence tools	`explain_levels`, `vol_context`, `whats_changed`, `market_brief`, `flow_context`

Tempest tools depend on your plan; without access they return not_entitled at no charge. OHLCV price bars (Atlas) are available over REST, not MCP.

Pricing

Calls spend API credits: 1 credit = $0.001. A typical call costs 1 to 5 credits.
Failed calls are free: any 4xx or 5xx is refunded.
`account_usage` is free and returns your balance and limits. Each tool result's meta includes the remaining balance.
Per-tool costs: tool catalog. Plans and included credits: www.skylit.ai/pricing.

REST API

The same data is available over REST with the same key. Each host serves its OpenAPI spec at /v1/openapi.json:

Host	Data
`https://api.skylit.ai`	Dealer positioning (Heatseeker), volatility (Tempest), options flow and dark pool (Flowseeker), account
`https://flow-api.skylit.ai`	Options flow and dark pool (alias for the Flowseeker paths)
`https://atlas-api.skylit.ai`	OHLCV price bars (Atlas)

See examples/python/rest-quickstart and the API reference.

The examples are research agents. They read data and never place orders; order execution is left to your own broker.
