# Massive — AI Connector Massive publishes 4 MCP tools to Claude and is listed in the ChatGPT apps directory. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/developer-tools/massive/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Developer Tools](https://node8.ai/ai-connectors/developer-tools/) # Massive Multi-asset market data from a licensed financial API Listed in ChatGPT and Claude · 4 published tools · Community-listed [ChatGPT listing](https://chatgpt.com/plugins/massive?open_in_app) [Claude connector docs](https://massive.com/docs) [massive.com](https://massive.com/) Overview ## What Massive does Massive routes questions to a market data API covering US equities and ETFs, listed options, futures, indices, foreign exchange, and crypto. Real-time and historical requests are both in scope, down to tick-level trades and quotes, OHLC bars, and market snapshots. Options coverage takes in chains, prices, open interest, and history across the listed US market. Futures contracts, index values, currency pairs, and crypto prices follow the same pattern of current and historical access. Beyond price series there are company fundamentals and financials, dividends and splits, market news, market status, and calculated indicators such as SMA, EMA, MACD, and RSI. Requests are phrased in plain language, and the data is described as licensed and exchange-sourced. The stated audience is traders, quants, analysts, and developers. ### Who it is for Quantitative analysts and developers who would otherwise write code against a market data API. ### What stands out One connector spans equities, options, futures, indices, forex, and crypto instead of a single asset class. Availability ## Where Massive is listed Massive.com, Inc. ships this on both marketplaces: Massive is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain. Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process. ChatGPT listing ## In the ChatGPT apps directory Developer Massive.com, Inc. Filed under Finance Listed since July 2026 Authentication Authenticates when installed Website [massive.com](https://massive.com) Policies published Privacy policy · Terms of service Official listing [Open in ChatGPT](https://chatgpt.com/plugins/massive?open_in_app) Snapshot August 2026 Claude listing ## In the Claude connectors directory Massive publishes 4 tools to Claude, a deliberately narrow surface; only 17.2% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Developer Tools publishes 13, so this one sits 9 tools below its bucket's median, 72nd of 95. It falls in the 4-6 tools band, which holds 16.2% of the Claude directory. Massive publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Massive.com, Inc. Verification Community-listed (61.5% of the Claude directory) Filed under Developer Tools Endpoint `https://mcp.massive.com/` Documentation [Publisher setup docs](https://massive.com/docs) Published tools 4 · 4-6 tools band Depth rank in Developer Tools 72 of 95 Snapshot August 2026 Massive is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
