The Potomac Ledger

For AI · Model Context Protocol

Use The Potomac Ledger in your AI assistant

Connect our live data to Claude, ChatGPT, or any MCP-capable tool and ask about the stock trades of Congress and senior executive-branch officials — in plain language, answered straight from official disclosures.

The endpoint

https://potomacledger.com/mcp

Free covers the last 90 days, no key required. A Pro key unlocks the complete archive (see below). Streamable HTTP (MCP).

Connect it

Claude Code — one line:

claude mcp add --transport http potomac-ledger https://potomacledger.com/mcp

Claude Desktop or other clients — add a remote MCP server pointing at the endpoint above. For clients without native remote support, bridge it locally:

npx mcp-remote https://potomacledger.com/mcp

Then just ask

What it can do

search_trades — filter by person, ticker, branch, buy/sell, conflict, amount, date
get_person_trades — every disclosed trade for a member or official
get_ticker_activity — who traded a given stock
list_recent_trades — the latest disclosures
list_conflicts — trades that overlap an official's committee or agency
aggregates — totals, top sectors, most-active officials, date range

Every response carries the same framing: disclosed date is not the trade date, dollar figures are ranges, conflict flags are potential overlaps (not accusations), and nothing here is investment advice.

Pro — the complete archive

The free tier covers the last 90 days. Pro unlocks the entire history (every disclosed trade we've recorded) and raises the limit to 500 requests/day — for researchers, journalists, and developers building on the data.

$35/month or $350/year. After checkout, your API key is emailed within a few minutes; connect it by adding --header "Authorization: Bearer YOUR_KEY" to the command above.
