No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/wa_bill_amendments for the schema, then POST the same URL with its arguments for the data.

List the AMENDMENTS proposed to a Washington State legislative bill — amendment name/drafting number, sponsor (member or committee), type (floor/committee), description, floor action (ADOPTED/FAILED/WITHDRAWN) and date, with links to the amendment text. Returns the most recent amendment first and a count by floor action. Reads directly from the Washington State Legislature’s own bill-tracking service. Use for “what amendments have been offered to HB 1002”, “was the striker amendment adopted on SB 5016”. A bill with no amendments on file returns an empty list, not an error. Keyless. For the bill’s overall status use wa_bill_status.

Parameters

bienniumstringnoWashington biennium, e.g. “2025-26” or a year like “2026”. Omit for the current biennium.
