Dialer MCP Server
An MCP server that provides lets you make outbound phone calls using your own phone number
What is the Dialer MCP Server?
The Dialer MCP server gives AI agents structured, permission-aware access to Dialer through the Model Context Protocol. With 0 pre-built actions, agents can read, create, and update Dialer data on behalf of authorized users.
Willow ships the Dialer MCP server as part of an enterprise control plane. Every call runs behind SSO (Okta, Azure AD), enforces RBAC and least-privilege at runtime, writes to a full audit trail, and integrates with Splunk and Loki for SIEM visibility. Connect from Claude Desktop, Claude Code, Cursor, ChatGPT, VS Code, n8n, or any custom agent. Install once, distribute org-wide, and see exactly how Dialer is being used by every AI agent in your stack.

Dialer MCP Server FAQ
What is the Dialer MCP server?
The Dialer MCP server is a Model Context Protocol implementation that lets AI agents like Claude, Cursor, and ChatGPT read and write Dialer data through a standardized interface. Willow hosts and governs this server so enterprises can roll it out without a security review backlog.
How is Willow's Dialer MCP server different from the official one?
The official Dialer MCP server is scoped to a single user's account and does not include enterprise governance. Willow's version adds SSO, RBAC, audit logging, shadow AI detection, and centralized control over which actions agents can take across the entire org.
Which AI clients work with the Dialer MCP server?
Claude Desktop, Claude Code, Cursor, ChatGPT, VS Code with MCP support, n8n, and any custom agent built with OpenAI Agents SDK, LangChain, Vercel AI SDK, or Anthropic SDK.
Is the Dialer MCP server secure? How does Willow handle authentication?
Every call runs behind your existing SSO (Okta, Azure AD). Per-user OAuth scopes the agent to exactly what that user can do in Dialer, nothing more. No credentials reach the LLM. Every action writes to an audit trail.
Can I limit which Dialer actions agents can take?
Yes. Willow lets you scope agents to specific actions, specific projects, or specific environments. Toggle actions on or off in the dashboard, or enforce policy via infrastructure-as-code through GitHub.
How do I detect shadow Dialer MCP servers in my org?
Willow's browser extension and discovery service surface unmanaged MCP servers, skills, and AI agents across the org. If a developer installed an unapproved Dialer MCP locally, you'll see it.
What does the Dialer MCP server cost?
Pricing depends on org size and deployment model (SaaS, dedicated cloud, self-host). See withwillow.ai/pricing or contact sales for a quote.
How do I install the Dialer MCP server with Willow?
Install via the Willow Connect Panel in one click, or paste the JSON snippet above into your Claude Desktop, Cursor, or Claude Code config. SSO and RBAC inherit from your existing Willow setup.
