Step 4: Confirm Willow is Active in the Chat​

Start a new conversation. Click the + button in the message bar and go to Connectors. Make sure the Willow toggle is on. You can also set how tools load:

  • Load tools when needed: tools are fetched on demand. Chats compact less often.
  • Tools already loaded: tools are always available. Chats may compact more often.

Step 5: Verify It Works​

Ask Claude:

"List what tools you have access to in Willow MCP"

Claude should respond with a full breakdown of your connected Willow tools.

The tools you see will depend on which MCP servers your organization admin has installed, which tools on those servers they have enabled, and what tools each MCP server exposes. Your list may look different from the one shown here.

Using Tools in Conversations​

Tools from Willow appear automatically in Claude conversations when the integration is active. Claude will choose to use them when relevant to your request.

If you want to confirm tools are available before asking a question, use the integrations icon in the message bar to see which integrations are connected to the current conversation.

Troubleshooting​

No tools visible after setup

  • Go to Customize → Connectors and confirm Willow shows as connected under Web
  • Start a new conversation. Connectors may not apply to existing conversations.
  • Re-authorize if the status shows disconnected

Authorization failed

  • Make sure you're logged in to your Willow account and have accepted the invite from your admin
  • Try the authorization flow again from Customize → Connectors → Willow → Connect
