Overview

AI-generated overview

Read-only access to parsed U.S. congressional stock trade disclosures (STOCK Act filings), with member, ticker, filing and compliance views.

What you can do
Browse the newest STOCK Act filings and individual disclosed trades, with paging and filters by ticker or member, and open a single filing with its parsed trades and source link. Look up members of Congress by name and see their profile, trading stats and recent trades, or see every member who disclosed trading a given ticker. Find stocks several members traded in the same direction, rank members by trading activity, compare members' 90-day purchase returns against the S&P 500, and check disclosure lag against the 45-day window.
When to use it
Useful when a question involves what members of Congress have disclosed trading, who traded a particular stock, or how promptly Congress reports trades. Suited to research and monitoring of public filings rather than trading execution.
Requirements
Remote streamable HTTP endpoint; no local install. Three tools work without authentication; the other eight need an Authorization header carrying a Bearer agent token from a free Coldpine account.
Before you install
The Authorization header carries a secret token; keep it private. Data is limited to parsed public filings and may lag or miss filings, and the provider notes most members do not beat the market. Read-only, with no trading or write actions.

Installation

In SourceWeft

  1. Open Coldpine: Congressional Stock Disclosures in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.coldpine%2Fcongress-disclosures/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

whats_new

Latest congressional disclosures

The newest STOCK Act Periodic Transaction Reports filed by members of Congress, newest first. Use this to answer 'what did Congress just disclose' or to poll for new filings: pass `since` (YYYY-MM-DD) to get only reports filed after that date. Returns one row per report: filing_id, filed_date, member name/id, chamber, party, state, trade count, buys, sells, distinct tickers, whether any trade was reported past the 45-day window, the top tickers, and the coldpine.io URL of the report and the member. Looks at the 100 most recent reports; for older ones page through list_recent_filings, and for the trades inside one report call get_filing. Access: no key or account needed. Read-only, cached for up to an hour.

Parameterslimitsince

search_members

Search members of Congress

Find members of the U.S. House or Senate who have disclosed stock trades, by full or partial name. Start here whenever a question names a person: it returns the member_id that get_member and list_transactions take. Each match carries name, chamber, party, state, trade and filing counts, buy/sell split, the disclosed dollar volume range and the member's coldpine.io page. total_matches tells you when the list was cut by `limit`. To rank all members rather than look one up, use congress_leaderboard. Access: no key or account needed. Read-only, cached for up to an hour.

Parameterslimitqueryrequiredchamber

get_member

Member profile and recent disclosed trades

One member of Congress: profile, aggregate trading stats (counts, volume range, average disclosure lag, most-traded tickers), the 20 most recent disclosed trades with links to the original government filing, the member's 5 most recent Periodic Transaction Reports, and the one sample scored trade the public page shows. Use it for 'what has this member been trading'. Get the member_id from search_members first. For more than 20 trades, page list_transactions with the same member_id. Returns a not-found error for an unknown id. Access: needs the agent token from a free Coldpine account, sent as 'Authorization: Bearer <token>'; without it the call returns setup steps instead of data. Read-only, cached for up to an hour.

Parametersmember_idrequired

get_stock

Congressional trading in one stock

Every member of Congress who disclosed trading a ticker: totals, buy/sell split, disclosed volume range, first and last trade dates, the members who traded it most, the 20 most recent disclosed trades with source-filing links, and the one sample scored trade the public page shows. Use it for 'who in Congress trades this stock'. For the full trade history of a ticker, page list_transactions with the same ticker; for stocks several members bought or sold together, use cluster_trades. Returns a not-found error when no member has disclosed a trade in the symbol. Access: no key or account needed. Read-only, cached for up to an hour.

Parameterstickerrequired

list_transactions

Disclosed trades, newest first

Individual disclosed congressional stock trades, newest disclosure first. The paging tool: use it when get_member or get_stock's 20 most recent trades are not enough, or to walk the whole record. Filter by ticker, by member_id, by both (one member's trades in one stock), or by neither (every trade). Each row has the ticker and asset name, purchase/sale/exchange, trade date, disclosure date, days between them, whether that passed the 45-day STOCK Act window, the reported amount range, the owner (self, spouse, dependent child), the member, and a link to the original House Clerk PDF or Senate eFD filing. `total` is the full match count, so keep raising `offset` by `limit` until you reach it. Access: needs the agent token from a free Coldpine account, sent as 'Authorization: Bearer <token>'; without it the call returns setup steps instead of data. Read-only, cached for up to an hour.

Parameterslimitoffsettickermember_id

list_recent_filings

Recent Periodic Transaction Reports

The newest Periodic Transaction Reports (STOCK Act filings) with parsed trades, newest filed date first, 25 per page: member, chamber, filed date, trade count, buy/sell split, tickers, and how many trades were reported more than 45 days after the trade (late_45). Mirrors coldpine.io/filings. Use it to browse the archive of reports page by page; `coverage` in the response gives the total number of reports, members and the date span, so you know how many pages exist. For just the latest reports or polling by date, whats_new is lighter and needs no token; for the trades inside one report, pass its id to get_filing. Access: needs the agent token from a free Coldpine account, sent as 'Authorization: Bearer <token>'; without it the call returns setup steps instead of data. Read-only, cached for up to an hour.

Parameterspage

get_filing

One Periodic Transaction Report, parsed

A single STOCK Act Periodic Transaction Report: who filed it and when, the roll-up (trade count, buy/sell split, tickers, amount range, longest disclosure lag, trades past the 45-day window, trades by spouse or dependent child), every trade it disclosed, a link to the original government document, and the one sample scored trade the public page shows. Use it after whats_new, list_recent_filings or get_member has given you a filing id and the question is about what that one report contained. Returns a not-found error for an unknown id. Access: needs the agent token from a free Coldpine account, sent as 'Authorization: Bearer <token>'; without it the call returns setup steps instead of data. Read-only, cached for up to an hour.

Parametersfiling_idrequired

cluster_trades

Cluster buys and sells

Stocks that several members of Congress traded in the same direction inside a rolling window (Coldpine's cluster detection, same definition as the bot). Returns ticker, direction, distinct member count, trade count, date span, summed disclosed amount range and the member names. Same data as coldpine.io/research/biggest-cluster-buys-in-congress. Use it for 'what are several members buying (or selling) at once'; for everyone who ever traded one given stock use get_stock instead. The window counts back from the most recent trade date on record, not from a date you choose, and clusters come back largest first by distinct members. A person is counted once per cluster however many trades they made. Overlap in timing is a description of the filings, not evidence of coordination. Access: needs the agent token from a free Coldpine account, sent as 'Authorization: Bearer <token>'; without it the call returns setup steps instead of data. Read-only, cached for up to an hour.

Parameterslimitdirectionmin_memberswindow_days

congress_leaderboard

Most active traders in Congress

Members of Congress ranked by disclosed trading activity: trade count, disclosed dollar volume (sum of amount-range midpoints), average trade size, or disclosure speed. Optional chamber and party filters. Same data as coldpine.io/leaderboard. Use it for 'who trades the most in Congress' style questions. Each row has the member, chamber, party, state, trade count, disclosed volume, average trade size, average days from trade to disclosure and the member's coldpine.io page; total_members is the count after filters. This ranks activity only. For returns against the S&P 500 use members_vs_market, and for late filing use stock_act_compliance. Access: needs the agent token from a free Coldpine account, sent as 'Authorization: Bearer <token>'; without it the call returns setup steps instead of data. Read-only, cached for up to an hour.

Parameterssortlimitpartychamber

members_vs_market

Members' disclosed purchases vs the S&P 500

Per-member 90-day return on disclosed stock purchases versus the S&P 500 over the same windows (alpha), with the 30-day alpha and hit rate. Only members with at least min_trades priced purchases that have a full 90-day window. Most members do not beat the market; this is the measured record. Same data as coldpine.io/research/members-who-beat-the-market. Use it when the question is about performance; congress_leaderboard ranks activity and carries no returns. Rows come back highest 90-day alpha first, each with the number of purchases measured, the average 90-day return, the S&P 500 average over the same windows, the 90-day and 30-day alpha, the share of purchases that beat the index, and the member's page. The response states the method. These are measured past outcomes on disclosed purchases only (sales and trades younger than 90 days are excluded), not a forecast and not a reason to trade. Access: needs the agent token from a free Coldpine account, sent as 'Authorization: Bearer <token>'; without it the call returns setup steps instead of data. Read-only, cached for up to an hour.

Parameterslimitmin_trades

stock_act_compliance

STOCK Act disclosure lag and late filers

How quickly Congress reports its trades against the STOCK Act's 45-day window: the site-wide summary (median lag, share late, House vs Senate) and the per-member board (trades dated, average and median lag, trades past 45 and 90 days, share late). Where a member has at least 5 priced purchases, the average pre-disclosure move of those purchases is given WITH the S&P 500 move over the same windows (avg_lag_excess); never quote one without the other. Same data as coldpine.io/research/congress-stock-act-late-filers. Use it for 'who files late' and 'how late is Congress overall'; the site-wide `summary` comes back on every call whatever the sort. For one member's lag on individual trades, read disclosure_lag_days in get_member or list_transactions. A late report is a fact about the filing date; it is not a finding of wrongdoing. Access: needs the agent token from a free Coldpine account, sent as 'Authorization: Bearer <token>'; without it the call returns setup steps instead of data. Read-only, cached for up to an hour.
