atlas vs plumb-mcp

atlas: Atlas is an open-source local-first cognitive memory system that implements AGM-compliant belief revision on a property graph. It adds a propagation engine called Ripple that recomputes downstream beliefs when an upstream fact changes. The system runs entirely on your laptop and includes a hash-chained ledger, continuous ingestion from multiple sources, and API surfaces for integration.; plumb-mcp: Plumb is a Figma-to-code MCP server with a built-in verification loop. It reads Figma via a desktop plugin (no rate limits, works on Free plans) and outputs a compact normalised design spec (PDS) instead of large JSON tokens. The unique verification tool drives headless Chrome to diff the rendered code against the original design, closing the loop on code quality.

Features

atlas logoatlas
01AGM-compliant belief revision (49/49 postulates verified)
02Ripple propagation engine for downstream belief reassessment
03Hash-chained SHA-256 ledger with tamper detection
04Continuous ingestion from 6 streams (Obsidian, Limitless, Screenpipe, etc.)
05MCP, HTTP, and gRPC API surfaces with adapters for agent runtimes
plumb-mcp logoplumb-mcp
01No rate limits: reads Figma via a plugin API, bypassing REST quotas and plan gates.
02Compact spec (PDS): deduplicates design tokens and resolves auto-layout to flexbox, reducing token count by 1–2 orders of magnitude.
03Verification loop: `plumb_verify` MCP tool and CLI diff rendered code against Figma design, outputting structured deltas.
04Twelve MCP tools: outline, node, tokens, assets, screenshot, verify, search, components, and more.
05Two data paths: plugin (no token, real-time) and REST (headless/CI, requires token).

Use Cases

atlas logoatlas
↳Pricing change invalidates positioning: updating a program price triggers reassessment of all value claims that depended on the old price.
↳Partner or person status change: a team member leaving triggers confidence drops in decisions and commitments that depended on them.
↳Deadline slips: a milestone moving weeks later triggers re-evaluation of all downstream project beliefs and contradictions.

↳Coding agents (Claude Code, Cursor, Windsurf) generating UI from Figma designs with verification to ensure pixel-perfect implementation.
↳CI/CD pipelines that automatically verify frontend code matches design specs using the `plumb-mcp verify` CLI.
↳Developers needing to extract structured design tokens, SVG icons, and PNG assets from Figma without rate limits or plan restrictions.
