{"jsonrpc":"2.0","id":1,"method":"tools/list"}hsr_recent — Get the most recent FTC Hart-Scott-Rodino (HSR) early-termination notices, newest first. When a merger clears HSR antitrust review early the FTC publishes a notice — for a private-target deal this is the earliest public signal the merger was filed and cleared, ahead of any 8-K or press release. Returns acquirer, target, transaction number and filing date. Answers "what mergers got antitrust clearance recently" or "which deals received HSR early termination this week." Example: hsr_recent({ days: 7, limit: 25 })hsr_search — Search FTC Hart-Scott-Rodino (HSR) early-termination notices by acquirer or target company name. Matches against the notice title, which embeds both parties and the transaction number, so a partial or one-sided company/fund name finds every notice that mentions it. Use this to check "did this merger get antitrust clearance" or "has the FTC granted HSR early termination for this deal." Example: hsr_search({ party: "Blockbuster", limit: 25 })hsr_party_history — Get every FTC Hart-Scott-Rodino (HSR) early-termination notice mentioning a given company or fund, oldest to newest, with a total count — a full antitrust-clearance history for that party across every deal the FTC granted early termination on. Example: hsr_party_history({ party: "Carl C. Icahn" })hsr_coverage — Report the size and date range of the FTC Hart-Scott-Rodino (HSR) early-termination notice dataset — total notice count, earliest and latest dates on record, and the 2021 suspension gap when the FTC paused granting early terminations for about five weeks. Call this before treating an empty hsr_recent, hsr_search, or hsr_party_history result as "no data" — it confirms whether the requested window actually falls inside FTC coverage. Example: hsr_coverage({})Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
