plumb_fit

MCP tool from Plumb MCP by tathagat22

The self-healing loop: verify + a 0–100 convergence score + prioritised fixes.

How to use it

Project documentation lists plumb_fit for the Plumb MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

Install Plumb MCP

$npm install -g plumb-mcp

Other tools in Plumb MCP (21)

plumb_assets

Export icons (SVG) + images (PNG) — recursive, list, or surgical by ids.

plumb_audit

Heuristic accessibility checks — text contrast, button touch-target size.

plumb_brand

Brief → live-screenshots best-in-class reference sites + a synthesized brand palette/type board on the canvas.

plumb_components

List components + instance usages, plus an opt-in design-system health report (unused components, near-duplicate names, variant outliers).

plumb_describe

Text-only visual description — for image-blind harnesses.

plumb_design

Author a design from Plumb's high-level Design DSL and build it into Figma (full control: pages, sections, components, motion).

plumb_diff

Semantic diff between two PDS snapshots — "the hero moved from (0, 0) to (0, 120)", not a JSON diff.

plumb_emit_react

Deterministic React/JSX generator from a PDS or a plumbimportweb result — same emitter, either source.

plumb_import_web

Import a live webpage's structure and semantics — no Figma connection needed. Same role classifier Figma designs use.

plumb_node

Extract a screen as compact PDS — by id or by name.

plumb_outline

Every screen in the file (id, name, size).

plumb_query

Pull a slice (skeleton / buttons / text / components / role) when a full screen would blow the token budget.

plumb_review

The critique loop: blends a structural diff, a deterministic design rubric, and the calling agent's own vision verdict into one score + ranked fixes. No API key — the agent that drives the MCP server is the creative director.

plumb_screenshot

Render any node to PNG/JPG.

plumb_search

Find nodes by name and/or type.

plumb_selection

The user's live Figma selection.

plumb_source

Resolve on-brief assets (icons, photos, illustrations, patterns) for a design.

plumb_status

Self-description, key legend, connection state. Call first.

plumb_studio

The design director. One brief → researched references → extracted brand → a full composed Figma page. Returns the node ids + authored spec so you can critique and refine.

plumb_tokens

Design-token table (colours, type, radii, shadows).

plumb_verify

Diff rendered layout against the design — ΔE2000 colour, shadow/rotation/flex checks.
