The Eraser MCP server lets AI coding agents — like Claude, Cursor, or GitHub Copilot — read and write diagrams and documentation in Eraser directly from your agentic workflows. It implements the Model Context Protocol (MCP) standard.

Which MCP clients are supported?

Eraser's MCP server works with all major MCP-compatible clients, including Claude (Anthropic), Cursor, GitHub Copilot, Windsurf, and Gemini. Both remote and local server configurations are supported.

How do I connect Eraser to my agent?

Each client has a one-click setup — click "Add MCP to [Client]" on the integration card for your tool. For manual configuration, add the Eraser MCP server URL or run it locally. Full docs are available at eraser.io/docs.

Is the MCP integration free?

Yes, MCP access is available on all plans including Free. Free plan teams can create up to 8 files and generate up to 20 AI diagrams. Upgrade to Pro or Enterprise for unlimited AI generations and additional team features.

Can agents edit diagrams automatically?

Yes. Agents connected via MCP can create new diagrams, update existing ones using diagram-as-code, and read your existing documentation as context — fully autonomously within the permissions you set.

What can agents do with Eraser context?

Agents can read your architecture diagrams, design docs, and notes as grounding context for code generation — and write back updated documentation or new diagrams as they build, keeping your docs in sync with your codebase.

Do I need to run a local server?

No. Eraser provides a hosted remote MCP server — no local setup required. A local server option is also available for teams with stricter network or security requirements.

What I love most is its Markdown note-taking feature, which allows you to include snapshots of diagrams directly in the canvas. Clicking on these snapshots takes you straight to the relevant diagram section.

As a proof of concept, using Eraser I manually built out a VMWare validated design which is a fairly complex conceptual design for NSX-T Network Virtualization in an enterprise environment. ... I put this whole thing together in under an hour. Pretty wild.

I've recently started using eraser.io and it's simply delightful: the best of Graphviz and Figma and code-to-diagrams in a neat UI.

All of the things that I was doing in 15 different places all in one place. It makes my architecture job easier. And committing back to the codebase is great.
