View on XOpenAI Updates Codex to Visualize System Architectures Directly in FigJam
OpenAI· Updated
OpenAI expanded its Codex agentic coding platform to autonomously generate architecture diagrams and implementation plans within FigJam. This shift moves AI assistance from pure code generation to the visual planning phase of the software development lifecycle.
OpenAI updated its Codex agentic coding platform with new capabilities for FigJam, the whiteboarding tool from Figma. Using the Model Context Protocol (an open standard for connecting AI to tools), the agent can now transform text-based implementation plans into visual architecture diagrams and Entity Relationship Diagrams (visual maps of database structures).
- Integration protocol
- Model Context Protocol
- Supported formats
- Architecture diagrams and ERDs
- Platform compatibility
- FigJam and Figma Design
This update builds on the bidirectional design-to-code workflow introduced earlier this year. While previous integrations focused on UI designs, this shift targets the planning phase. It extends OpenAI's persistent engineering workflows by allowing agents to maintain a visual source of truth synchronized with technical specifications.
You can now use the generate_diagram tool to build system maps or the figma-use-figjam skill to annotate boards. These features are available via the Codex API and the official Figma MCP server. Access follows the launch of OpenAI's usage-based Codex seats, which removed fixed monthly fees.
Still wondering? A few quick answers below.
OpenAI Codex can now autonomously generate visual implementation plans and system architectures directly on FigJam boards. It creates architecture diagrams and Entity Relationship Diagrams from text-based plans. This allows engineering teams to visualize their systems and add notes, code blocks, or annotations to a collaborative board instead of just reading raw code.
The integration uses the Model Context Protocol, which is an open standard that connects AI models to external tools and data sources. By using a dedicated Figma MCP server, Codex can pull structured design context and push visual content back to FigJam. This enables a bidirectional workflow where the AI reads and writes native Figma content.
The plugin includes three primary tools for FigJam workflows. The generate_diagram tool creates system maps and database structures. The figma-use-figjam skill allows the agent to place notes and code blocks on the board. Finally, the get_figjam tool enables Codex to read an existing board to map out and understand the systems described there.
These features are available to developers building with the OpenAI Platform and the Codex API. Users need to set up the Figma MCP server to connect their agentic tools to Figma Design and FigJam. The integration is designed for technical teams who want to automate the visual documentation of their software development lifecycle.
