`draw_constraint`

Pack: creative-constraints · 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/draw_constraint for the schema, then POST the same URL with its arguments for the data.

Draws from Pipeworx’s original 162-card creative-constraints deck (${CATEGORY_LIST}) — each card is one imperative sentence an agent or team can apply to any task (a launch, an essay, an onboarding flow, a dinner), with a one-sentence reason it helps.

Parameters

Name	Type	Required	Description
`count`	number	no	How many cards to draw, 1-${MAX_DRAW_COUNT}. Default 3.
`categories`	array	no	Restrict the draw to one or more of: ${CATEGORY_LIST}. Omit (or pass an empty array) for the full 162-card deck.
`items`	string	no
`seed`	string	no	Optional seed for a reproducible draw. The same seed, count and categories always return the same cards. Omit for a fresh random draw; the seed actually used is returned in `meta.seed`.
`session_id`	string	no	A session_id returned by a previous draw_constraint call, to continue drawing without repeating cards already drawn in that session. Hosted gateway only — answers session_supported:false elsewhere.
