## MCP tools (4)

### `hsr_recent` (~207 tokens)

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 })

Input parameters:

- `_apiKey` (string): Optional — your own api.data.gov key for higher limits; omit to use the shared Pipeworx key.
- `days` (number): How many days back from today to look. Default 7.
- `limit` (number): Max notices to return, newest first (paged from the source in batches of 50). Default 25, max 100.

### `hsr_search` (~241 tokens)

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 })

Input parameters:

- `_apiKey` (string): Optional — your own api.data.gov key for higher limits; omit to use the shared Pipeworx key.
- `limit` (number): Max notices to return, newest first. Default 25, max 100.
- `party` (string, required): Company or fund name to search for, e.g. "Blockbuster" or "Carl C. Icahn". Matches anywhere in the notice title (as-filed legal name, so include known fund suffixes like "L.P." if a plain name misses…
- `since` (string): Optional — only return notices on or after this date, YYYY-MM-DD.

### `hsr_party_history` (~153 tokens)

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" })

Input parameters:

- `_apiKey` (string): Optional — your own api.data.gov key for higher limits; omit to use the shared Pipeworx key.
- `party` (string, required): Company or fund name to search for, e.g. "Carl C. Icahn" or "American Securities Partners". Matches anywhere in the notice title (as-filed legal name).

### `hsr_coverage` (~141 tokens)

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({})

Input parameters:

- `_apiKey` (string): Optional — your own api.data.gov key for higher limits; omit to use the shared Pipeworx key.
