Connect Atlas MCP

Atlas MCP URL: https://atlaswork.ai/api/mcp

Pick OAuth for Claude and ChatGPT. Use a Bearer API key for Cursor, Claude Code, VS Code, and other dev tools.

Claude OAuth

Fastest path: open the one-click connector link. Claude opens the add-connector flow with Atlas pre-filled.

https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Atlas&connectorUrl=https://atlaswork.ai/api/mcp

Manual steps:

Open Claude Settings → Connectors.
Add custom connector. Name: Atlas. URL: https://atlaswork.ai/api/mcp.
Sign in to Atlas when prompted. Click Allow.
Start a new chat after connecting.

Signers get email only after you click Send on the review page.

ChatGPT

Open ChatGPT Settings → Apps & connectors.
Add Atlas with URL https://atlaswork.ai/api/mcp.
Sign in and authorize when prompted.
Start a new chat.

ChatGPT can attach a PDF or DOCX in chat. Other clients need an upload link for local files.

API key clients

Get your API key from Dashboard → Settings. Do not paste it into Claude or ChatGPT chat.

Cursor

~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "atlas": {
      "url": "https://atlaswork.ai/api/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Reload Cursor. Start a new chat.

Claude Code

claude mcp add atlas --transport http https://atlaswork.ai/api/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

Restart Claude Code.

Claude Desktop (API key)

~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "atlas": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote", "https://atlaswork.ai/api/mcp",
        "--header", "Authorization:Bearer YOUR_API_KEY"
      ]
    }
  }
}

Restart Claude Desktop. OAuth via Connectors is simpler if you use Claude on the web.

VS Code

.vscode/mcp.json in your workspace:

{
  "servers": {
    "atlas": {
      "type": "http",
      "url": "https://atlaswork.ai/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Reload the window. Requires a VS Code build with MCP support.

First message in chat

Paste this after you connect:

I use Atlas for e-signatures. Draft a short contract in this chat, then use Atlas to prepare it for review (not send yet). Share the review link when it's ready. I'll click Send on the review page before anyone gets an email.

Troubleshooting

Problem	Fix
Tools missing in chat	Start a new chat after connecting
Local PDF fails in Claude	Ask for an upload link, upload PDF or DOCX, say "done"
401 on dev tools	Check Bearer token in config. Rotate key in Settings if needed
Signers emailed too early	MCP only drafts. You must click Send on review
