Iris MCP Server

Multi-backend MCP gateway providing Google Drive write access, Notion, and more through a single MCP connector.

Overview

Iris solves the free-tier MCP connector limitation by acting as a gateway: users connect ONE custom connector (Iris) and get access to multiple backend services with full read/write capabilities.

Two Modes:

• Stdio Mode (Claude Desktop) - Production ready ✅

• HTTP Mode (Browser claude.ai) - Prototype 🧪 See HTTP-MODE-GUIDE.md

What Iris Provides

Google Drive Backend:

• ✅ iris_drive_write - Create or update files

• ✅ iris_drive_read - Read file contents

• ✅ iris_drive_create_folder - Create folder structures

• ✅ iris_drive_list - List files and folders

• ✅ iris_drive_move - Move or rename files

• ✅ iris_drive_delete - Delete files (with safety confirmation)

Coming Soon:

• Notion backend (read + write)

• Slack backend (send messages)

• Dropbox backend (read + write)

npm install

2. Configure environment:

cp .env.example .env
# Edit .env with your Google OAuth credentials

3. Build:

npm run build

4. Test locally:

npx @modelcontextprotocol/inspector node dist/index.js

HTTP Mode Setup (For Browser Claude.ai)

To use Iris with browser-based claude.ai:

# After completing OAuth setup above
npm run setup:browser  # Interactive wizard
npm run http           # Start HTTP server

See HTTP-MODE-GUIDE.md for complete browser integration guide.

Configuration

2. Create a new project or select existing

3. Enable Google Drive API

4. Create OAuth 2.0 credentials:

   • Application type: Web application

   • Authorized redirect URIs: https://iris.uncletallest.productions/oauth/callback

5. Copy Client ID and Client Secret to .env

Environment Variables

See .env.example for all required configuration.

Usage

Multi-Instance System Integration (Example Use Case)

Coordinating instance saves shared notes:

iris_drive_write({
  path: "coordination/shared-notes.md",
  content: "Instance A is handling task X, Instance B is tracking Y...",
  mode: "upsert"
})

Health tracking instance saves wellness data:

iris_drive_write({
  path: "wellness/tracking/2026-03.md",
  content: "# March 2026 Health Log\n\n## Week 1\n- Energy: 7/10\n- Sleep: 8hrs avg\n...",
  mimeType: "text/markdown"
})

Project tracking instance saves application data:

iris_drive_write({
  path: "projects/applications/applied-march.md",
  content: "| Company | Position | Applied | Status |\n|---------|----------|---------|--------|\n...",
  mode: "upsert"
})

Tool Examples

Create folder structure:

iris_drive_create_folder({
  path: "projects/active/project-alpha"
})
// Creates: projects/ → projects/active/ → projects/active/project-alpha/

List files:

iris_drive_list({
  path: "coordination",
  recursive: false,
  type: "both"
})

Read file:

iris_drive_read({
  path: "coordination/memory.md",
  asText: true
})

Move file:

iris_drive_move({
  sourcePath: "old-location/file.md",
  destinationPath: "new-location/file.md"
})

Delete file (with confirmation):

iris_drive_delete({
  path: "temp/old-notes.md",
  confirm: true,
  permanent: false  // Moves to trash, not permanent
})
