Eraser
Generate and iterate architecture, flow, and system diagrams plus related docs from chat without leaving your agent.
Overview
io.eraser/eraser is a MCP server for the Build phase that lets your agent generate, edit, and manage Eraser diagrams and docs via AI over streamable HTTP.
What is this MCP server?
- Remote streamable-http MCP at app.eraser.io/api/mcp (schema 2025-10-17)
- AI-assisted create, edit, and manage Eraser diagrams and linked documentation
- Keeps visual models and text in one Eraser workspace instead of scattered screenshots
- Fits pre-build planning sketches and mid-build architecture updates from natural language
- Version 0.2.0 published as io.eraser/eraser in MCP registry metadata
- Published server version 0.2.0
- Single remote endpoint: streamable-http at app.eraser.io/api/mcp
- MCP schema dated 2025-10-17 in server manifest
What problem does it solve?
You need accurate system and flow diagrams updated as fast as your ideas change, but redrawing in a separate design app breaks your agent-first workflow.
Who is it for?
Indie developers and small teams who live in Eraser for architecture sketches, RFCs, and visual specs and want the same surface callable from Claude Code or Cursor.
Skip if: Teams that only need inline Mermaid in markdown repos with no Eraser account, or builders who want automated deploy or IaC from diagrams alone.
What do I get? / Deliverables
After you connect the remote endpoint, your agent can create and revise Eraser diagrams and documentation in place so architecture stays aligned with what you are shipping.
- Updated Eraser diagrams from agent prompts
- Managed Eraser docs tied to your diagrams
- Shareable visual architecture artifacts in Eraser
Recommended MCP Servers
Journey fit
Diagrams and written specs most often land during active product construction, when structure and interfaces need to be communicated to yourself, cofounders, or AI assistants. Docs subphase covers architecture artifacts, RFC-style explanations, and visual system maps that accompany implementation—not just marketing copy.
How it compares
Hosted diagram-and-docs MCP integration, not a local codegen skill or infrastructure provisioner.
Common Questions / FAQ
Who is io.eraser/eraser for?
Solo and indie builders who already use or want Eraser for technical diagrams and want their coding agent to create and edit those assets conversationally.
When should I use io.eraser/eraser?
Use it during build and documentation passes when you need architecture, sequence, or product diagrams that must stay editable and shareable in Eraser.
How do I add io.eraser/eraser to my agent?
Register the remote MCP server URL https://app.eraser.io/api/mcp with streamable-http transport in Claude Desktop, Claude Code, Cursor, or any MCP client that supports hosted servers, then complete Eraser app authentication as prompted.
