HostWebhookAgents that don’t just answer.
They act in the apps you already use.
Hand a model real tools — Gmail, Calendar, Slack and more — with retries, approvals and every tool call on the record.
No credit card. Anthropic, OpenAI, Gemini, Groq or OpenRouter.
A visitor asks in the chat widget. The Concierge node holds three nodes in AI toolkit mode and picks which of their 41 tools to call.
Bring the model you trust
Every integration is a tool your agent can use
Put an AI node in the workflow, switch an integration to AI toolkit, and its actions become tools the model can call. You tick the ones it may use; the node checks the shape of every call before it runs.
Beyond integrations — six more places a tool can come from.
Add a server as a credential; its tools join the same picker.
https://mcp.linear.app/sseA webhook with Internal calls on becomes one tool that runs the whole flow behind it.
WorkflowEach store becomes a search tool, with top-K and minimum score set per store.
query_help_centerThe agent turns its answer into audio with OpenAI or ElevenLabs, ready to send as a Telegram voice note.
synthesize_voiceA tunnel opened with the CLI becomes a tool, so the agent can call a service on localhost.
hostwh exposePaste a curl, an OpenAPI URL or a plain description and a cheap model writes the tool spec for you.
custom HTTP toolThe model prepares it. A person says yes.
An AI node reads the email and returns a typed object — order, amount, reason. The Approval node waits for Finance for up to four hours, then rejects by default. Only then does Shopify refund.
Guardrails are a checklist on the agent, not a prompt you have to write.
Answers from your docs, refreshed every night
Firecrawl crawls the help center on a schedule and a Vector Store node indexes it. The support agent searches it as a tool.
A phone agent whose tools are your flows
Run the voice agent on ElevenLabs and link the nodes it may use. Each one lends its toolkit, so the agent can look the caller up in Airtable and offer free times from Calendly.
Your flows become tools for other agents
Point Claude or Cursor at your workspace and every trigger you expose is a tool it can call.
Add the server once. Its tools show up in the AI node’s toolkit next to Gmail and Sheets.

OAuth 2.1 with dynamic client registration, so there is no key to paste.

Still a webhook platform underneath
Every event is deduplicated, retried on your terms and kept with its payload. When an agent run fails, it waits in the dead-letter queue with its reason.
