Port Telegram's permission model (owner_id, dm_policy, allow_from, pairing codes)
to Discord, Slack, and WhatsApp WASM channels. Add web UI for configuration and
pairing approval. Fix extension registry issues preventing Discord install and
causing Slack activation to hit the wrong endpoint.
WASM channels:
- Discord: add DiscordConfig, permission checks, ephemeral pairing replies,
fix capabilities.json (header_name→name), downgrade wit-bindgen to 0.36
- Slack: expand SlackConfig with permission fields, add check_sender_permission
and send_pairing_reply via chat.postMessage
- WhatsApp: expand WhatsAppConfig with permission fields, add permission checks
and pairing reply via Cloud API
- Telegram: reformat capabilities.json, add setup.required_secrets
Extension system:
- Add Discord to KNOWN_CHANNELS in bundled.rs and to extension registry
- Rename "slack" MCP→"slack-mcp", "slack-channel"→"slack" to fix name collision
- Add ExtensionSource::Bundled variant handling in discovery.rs
- Add get_setup_schema/save_setup_secrets to ExtensionManager
- Add needs_setup field to InstalledExtension
Web gateway:
- Add GET/POST /api/extensions/{name}/setup for configuration modal
- Add GET /api/pairing/{channel} and POST /api/pairing/{channel}/approve
- Add configure modal UI (password fields, provided badges, auto-generate hints)
- Add pairing request UI on active WASM channel cards
- Show "Restart to activate" label instead of Activate button for WASM channels

Discord Channel for IronClaw
WASM channel for Discord integration - handle slash commands and button interactions via webhooks.
Features
- Slash Commands - Process Discord slash commands
- Button Interactions - Handle button clicks
- Thread Support - Respond in threads
- DM Support - Handle direct messages
Setup
-
Create a Discord Application at https://discord.com/developers/applications
-
Create a Bot and get the token
-
Set up Interactions URL to point to your IronClaw instance
-
Copy the Application ID and Public Key
-
Store in IronClaw secrets:
ironclaw secret set discord_bot_token YOUR_BOT_TOKENNote: The
discord_bot_tokensecret is the only value read directly by this Discord channel WASM component. Thediscord_app_idanddiscord_public_keysecrets are used by the IronClaw host (for example, to verify Discord interaction signatures and manage slash command registration) and are not accessed from the WASM module itself.
Discord Configuration
Register Slash Commands
curl -X POST \
-H "Authorization: Bot YOUR_BOT_TOKEN" \
-H "Content-Type: application/json" \
https://discord.com/api/v10/applications/YOUR_APP_ID/commands \
-d '{
"name": "ask",
"description": "Ask the AI agent",
"options": [{
"name": "question",
"description": "Your question",
"type": 3,
"required": true
}]
}'
Set Interactions Endpoint
In your Discord app settings, set:
- Interactions Endpoint URL:
https://your-ironclaw.com/webhook/discord
Usage Examples
Slash Command
User types: /ask question: What is the weather?
The agent receives:
User: @username
Content: /ask question: What is the weather?
Button Click
When a user clicks a button in a message, the agent receives:
User: @username
Content: [Button clicked] Original message content
Error Handling
If an internal error occurs (e.g., metadata serialization failure), the tool attempts to send an ephemeral message to the user:
❌ Internal Error: Failed to process command metadata.
Check the host logs for detailed error information.
Advanced Usage
Embeds
To send embeds, include an embeds array in the metadata_json field of the agent's response. The structure should match the Discord API embed object.
Troubleshooting
"Invalid Signature"
- Check that
discord_public_keyis set correctly in IronClaw secrets. - This validation happens on the host before reaching the WASM.
"401 Unauthorized"
- Check that
discord_bot_tokenis set correctly in IronClaw secrets. - Ensure the bot is added to the server.
"Interaction Failed"
- The interaction might have timed out (Discord requires a response within 3 seconds).
- The
interactions_endpoint_urlmight be unreachable.
