SPACInsider
Read-only SPAC data: universe, league tables, lockups and earnouts
Overview
What SPACInsider does
SPACInsider maintains data on special purpose acquisition companies. The connector queries it read-only: the current SPAC universe, point-in-time historical snapshots, IPO counts, underwriter league tables, participant relationships, corporate actions, and lockup and earnout terms. Point-in-time snapshots are the part worth noting, since they allow a question to be asked as of a past date rather than against a revised present-day view. Authorization runs through OAuth at spacinsider.com, twenty-nine tools are claimed, and the record is cross-filed under financial services.
Tool surface
OAuth sits in front of the server, so an unauthenticated tools/list gets a 401 and the twenty-nine tools remain a published number.
Availability
Where SPACInsider is listed
SPACInsider is listed in the Claude connectors directory only. SPACInsider has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
SPACInsider publishes 29 tools to Claude, deeper than 80.3% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Data & Analytics publishes 12, so this one runs 17 tools above its bucket's median and ranks 28th of 198 by tool count.
It falls in the 21-50 tools band, which holds 20% of the Claude directory.
SPACInsider 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.

SPACInsider 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.
In the publisher's words
How SPACInsider describes it
SPACInsider provides read-only access to comprehensive SPAC market data through a hosted MCP server. Ask questions about the SPAC universe, point-in-time historical snapshots, IPO counts, underwriter league tables, participant relationships, corporate actions, and lockup/earnout terms. The connector uses OAuth via spacinsider.com. Data is retrieved through structured MCP tools.
