Frequently Asked Questions
How do I connect Vapi to my app?
Use Weavz Hosted Connect for API Key authentication. Install the SDK, create a connection through the connect portal or API, then execute tools programmatically.
What tools does Vapi support?
Vapi supports 6 tools including Create Assistant, List Assistants, Create Call, Get Call, List Calls, and more.
Can I use Vapi with AI agents?
Yes. Add Vapi to an MCP server in Tool Mode or Code Mode. Code Mode provides 3 meta-tools with on-demand API discovery so agents can compose stateful workflows without loading every action schema up front.
How do I connect Vapi to ChatGPT or Claude?
Open the Weavz connector setup, sign in, choose a workspace, and add Vapi as an approved app. ChatGPT, Claude, and other remote MCP clients can then call the scoped Vapi tools exposed by that workspace.
Does Vapi work with Claude Code, Cursor, Codex, and local agents?
Yes. Remote and local MCP clients can connect to a Weavz MCP endpoint for the workspace. Local coding agents can also use the Weavz CLI to inspect apps, discover actions, run approved Vapi work, and execute Code Mode workflows from a terminal.
What can I ask an AI agent to do with Vapi?
Vapi exposes 6 tools, including Create Assistant, List Assistants, Create Call, Get Call, List Calls, and more. Use Weavz to keep credentials scoped, require approval for sensitive work, and audit what the agent did.
Can Vapi be used in stateful agent workflows?
Yes. Agents can combine Vapi tools with Filesystem, State KV, Human Gates, input partials, and other workspace integrations while keeping execution scoped to the selected workspace or end user.
What authentication does Vapi use?
Vapi uses API Key. Weavz stores credentials securely and uses them for authorized action execution.
