Pack: dailymed · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

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

List pharmacologic drug-class reference entries from DailyMed, optionally filtered by class_code or class type (EPC = established pharmacologic class, MoA = mechanism of action, PE = physiologic effect, CS = chemical structure). Returns class codes and display names. ~1,210 classes total, 100 per page.

Parameters

Name	Type	Required	Description
`class_code`	string	no	Restrict to a specific class code. NLM RxClass format, e.g. “N0000175809” — not a UMLS CUI.
`type`	string	no	EPC \| MoA \| PE \| CS
`page`	number	no	1-based page (100 per page, ~13 pages). Ignored when class_code is given.
