Eraser

MCP server by Eraser

Generate, edit, search and export Eraser diagrams and docs from your AI assistant.

OAuth sign-in (You sign in with the vendor the first time you connect)Streamable HTTP

Connect to Eraser

Eraser needs sign-in. Connect with its own URL:

https://app.eraser.io/api/mcp

Your client opens Eraser’s sign-in the first time you use it. The token stays between your client and Eraser.

About

Connects an assistant to Eraser, a diagramming tool for technical teams. According to the vendor, it supports diagram create, search, update and export from clients such as Claude, Cursor and ChatGPT, and can ground diagrams in code and images.

The server is hosted at app.eraser.io over streamable HTTP. Users sign in with OAuth. The vendor's documentation also mentions API tokens and stdio transport for headless agents.

What you can do

  • Generate diagrams from text prompts
  • Edit and update existing diagrams
  • Search and manage diagrams and docs
  • Export diagrams
  • Ground diagrams in code and images

Tools

Eraser lists its tools only after you sign in, so we can’t show them here. Your client lists them once you’re connected.

Example prompts

  • Create a diagram of our AWS architecture with a load balancer, EKS and RDS

  • Update my checkout flow diagram to add a fraud check step

  • Search my Eraser workspace for diagrams about authentication

  • Export the payments architecture diagram as an image

Set up

Every client connects to app.eraser.io, and Eraser asks you to sign in the first time. Pick yours; the page remembers your choice.

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport http eraser https://app.eraser.io/api/mcp
  1. Start Claude Code, type /mcp, pick eraser and choose Authenticate. A browser window opens for the Eraser sign-in.

Add --scope user to make it available in every project, not just this one.

Claude Desktop

  1. Open Settings → Connectors and click Add custom connector.
  2. Name it Eraser and paste this URL:
https://app.eraser.io/api/mcp
  1. Click Add, then Connect, and sign in when Eraser asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

claude.ai

  1. Open the connector form on claude.ai. This button fills in the name and URL for you:
  1. Check that the URL reads https://app.eraser.io/api/mcp and click Add.
  2. Click Connect and sign in when Eraser asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.

ChatGPT

  1. On chatgpt.com, open Settings → Security and login and turn on Developer mode.
  2. Go to chatgpt.com/plugins and click + to create an app for a remote MCP server.
  3. Paste https://app.eraser.io/api/mcp as the server URL and choose OAuth. ChatGPT sends you to Eraser to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

Cursor

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json
{
  "mcpServers": {
    "eraser": {
      "url": "https://app.eraser.io/api/mcp"
    }
  }
}

Cursor shows Needs login next to the server. Click it to sign in.

VS Code

Or from a terminal:

code --add-mcp '{"name":"eraser","type":"http","url":"https://app.eraser.io/api/mcp"}'

Or commit it to the repo in .vscode/mcp.json:

.vscode/mcp.json
{
  "servers": {
    "eraser": {
      "type": "http",
      "url": "https://app.eraser.io/api/mcp"
    }
  }
}

VS Code asks you to sign in the first time the server starts.

Devin Desktop

  1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):
mcp_config.json
{
  "mcpServers": {
    "eraser": {
      "serverUrl": "https://app.eraser.io/api/mcp"
    }
  }
}
  1. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.

Codex

codex mcp add eraser --url https://app.eraser.io/api/mcp
codex mcp login eraser

Or edit ~/.codex/config.toml directly:

config.toml
[mcp_servers.eraser]
url = "https://app.eraser.io/api/mcp"

Gemini CLI

gemini mcp add --transport http eraser https://app.eraser.io/api/mcp

Then, inside Gemini CLI, run /mcp auth eraser to sign in.

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI’s settings file.

{
  "mcpServers": {
    "eraser": {
      "type": "http",
      "url": "https://app.eraser.io/api/mcp"
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://app.eraser.io/api/mcp.

FAQ

Can I paste mcp.tc/i/eraser into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://app.eraser.io/api/mcp, so your client talks to Eraser directly. The sign-in token only works there anyway. The quick link is for sharing: it opens this page, with setup steps for every client.

Does Eraser need an API key or a sign-in?

Yes, you need a Eraser account. The first time your client connects, it opens Eraser’s sign-in page. The token goes straight to the server’s own URL, never through mcp.tc.

Is Eraser a remote or a local server?

Remote. Eraser hosts it at https://app.eraser.io/api/mcp, and it speaks Streamable HTTP. There’s nothing to install.

What can Eraser do?

You can generate diagrams from text prompts, edit and update existing diagrams and search and manage diagrams and docs.

Which clients can use it?

Any client that supports remote MCP servers: Claude Code, Claude Desktop, claude.ai, ChatGPT in developer mode, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. The setup steps cover each one.

Who wrote this page?

mcp.tc’s robot read Eraser’s own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can’t confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
