ProBors

Research & Analysis — Paid

Tracks Congress, insider and whale stock disclosures with AI research, alerts, a REST API and MCP.

Congress and insider trade data with an MCP server

Overview

ProBors is a disclosure research workspace. It tracks stock trades reported by members of Congress under the STOCK Act, SEC Form 4 insider activity and large whale transactions, and puts them next to market context. It is for investors who use public filings as an idea source and want them in one place. It is known for pairing that data with an MCP server, so tools like Claude and Cursor can query it.

You get dashboards of filings as they post, politician portfolios, signal scores, watchlists and alerts. A Portfolios tab lets you combine politician holdings, set weights and simulate the mix against SPY. The AI research feature writes briefs on filings and answers questions, metered by monthly AI credits. A REST API and the MCP server cover automation and agents. There is an iOS app.

The catch: disclosures are late by design. Congressional filings can trail the trade by weeks, so this is research, not a live copy-trading feed. The site names no founder or company. Prices load by script, and the figures we saw were $30 a month at a launch rate against a regular $75, or $180 a year, with a 14-day refund window and no stated free trial. Confirm at checkout. Skip it if you want real-time signals.

Pros

• Congress, insider and whale data together
• REST API plus MCP for Claude and Cursor
• AI research briefs on public filings

Cons

• No founder or company named on site
• No free trial, refund window only
