`search_filings`

Pack: senate-lobbying · Endpoint: https://gateway.pipeworx.io/senate-lobbying/mcp

Search US Senate Lobbying Disclosure Act (LDA) filings — federal lobbying disclosures showing who is lobbying the US government, for which client, on what issues, and for how much. Lobbying FIRMS/registrants report income (what the client paid them); IN-HOUSE lobbyists report expenses (what they spent on their own lobbying). Provide at least one filter. Keyless.

Parameters

Name	Type	Required	Description
`registrant_name`	string	no	Lobbying firm / registrant name, e.g. “akin”, “Brownstein”. Partial match.
`client_name`	string	no	Client name — who hired the lobbyist, e.g. “Google”, “Pfizer”. Partial match.
`filing_year`	number	no	Filing year, e.g. 2024.
`issue`	string	no	Topic to match against each filing’s specific lobbying-issue description. Either a phrase (“drug pricing”, “semiconductor tariffs”) or a general issue area code from list_issue_codes (“TAX”, “HCR”, “DEF”), which is resolved to its official name before searching. Matches filings that DESCRIBE this topic, which is close to but not identical with the area code a filing is filed under.
`filing_type`	string	no	Optional filing type code, e.g. “Q1”/“Q2”/“Q3”/“Q4” (quarterly reports), “RR” (registration). Use to narrow to a specific period/form.
`limit`	number	no	Max results, default 10, max 25.
