list_assistants

List Assistants

List voice AI assistants in your Vapi account. Supports pagination and filtering by creation or update timestamps.

list_files

List Files

List files uploaded to your Vapi account. Files can be used as knowledge sources for assistants' retrieval-augmented generation.

Configure function and direct API request tools with the typed fields, or use configuration for other current Vapi tool types such as endCall, handoff, and transferCall.

Discover squads and their assistant members before managing squads or creating calls.

Connect Vapi to your AI client

Every client uses the same Magic MCP URL, and so does any other MCP client. Add it once and sign in with SSO.

  1. Enable Vapi in Metorial. In your Metorial portal, enable the Vapi MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Vapi tools.

Run Vapi through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Vapi and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Vapi tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.
