modbender pdauth — Dynamic OAuth for AI Agents
Use pdauth to give yourself (the agent) access to 2500+ APIs via OAuth. The flow:
- Agent needs access to an app (Spotify, Slack, Notion, etc.)
- Generate an OAuth link with
pdauth connect <app> - Share link with user → they click and authorize
- Agent can now call tools via
pdauth call <app.tool>
Quick Reference
# Configure (one-time setup)
pdauth config
# Search for apps
pdauth apps --search spotify
# Generate OAuth link
pdauth connect spotify --user USER_ID
# Check what's connected
pdauth status --user USER_ID
# List available tools
pdauth tools spotify --user USER_ID
# Call a tool
pdauth call spotify.get_my_playlists --user USER_ID
pdauth call slack.send_message channel=general text="Hello!"
The OAuth Flow (How to Request Access)
When you need access to an app the user hasn't authorized:
1. Run: pdauth connect <app> --user <user_id>
2. Get the OAuth link from output
3. Send link to user: "To do this, I need access to <App>. Click here to authorize: <link>"
4. User clicks, authorizes via Pipedream
5. Confirm with: pdauth status --user <user_id>
6. Now you can call tools!
User ID Strategy
Use a consistent identifier per user:
- Telegram:
telegram:5439689035 - Email:
pedro@example.com - Custom:
pedro-mainframe
The same user ID across sessions maintains their connected accounts.
Calling Tools
# Format: pdauth call <app>.<tool_name> [key=value ...]
# Simple args
pdauth call slack.send_message channel=general text="Hello"
# JSON args for complex data
pdauth call notion.create_page --args '{"title": "My Page", "content": "..."}'
# Get JSON output for parsing
pdauth call spotify.get_my_playlists --json
Checking Status
# See what user has connected
pdauth status --user pedro
# See all users
pdauth status --all
# JSON for scripting
pdauth status --user pedro --json

Error Handling
"App not connected" → Generate link with pdauth connect and ask user to authorize
"Tool not found" → List available tools with pdauth tools <app>
"Invalid credentials" → Run pdauth config to set up Pipedream credentials
Tips
- Always check status first before attempting tool calls
- Use consistent user IDs so connections persist across sessions
- JSON output (
--json) is best for parsing results programmatically - Link expiry — OAuth links expire after 4 hours, generate fresh ones as needed
Example Workflow
User: "Add 'Bohemian Rhapsody' to my Spotify playlist"
Agent:
1. pdauth status --user telegram:5439689035 --json
→ No Spotify connection
2. pdauth connect spotify --user telegram:5439689035
→ Gets OAuth link
3. Send to user: "I need Spotify access. Click here: <link>"
4. User authorizes
5. pdauth status --user telegram:5439689035
→ Spotify ✓ connected
6. pdauth call spotify.search_tracks query="Bohemian Rhapsody" --json
→ Get track ID
7. pdauth call spotify.add_to_playlist playlist_id=... track_id=...
→ Done!
8. Reply: "Added Bohemian Rhapsody to your playlist! 🎵"
