# DialMCP > A hosted remote MCP server that lets an MCP-enabled AI agent place a real outbound phone call on a user's behalf, using the user's own SMS-verified caller ID. ## What DialMCP is DialMCP connects AI agents to the phone network through the Model Context Protocol (MCP). It places calls to US and Canadian numbers, navigates phone trees and hold, and returns a structured outcome, transcript, and recording link. Calls are asynchronous: `place_call` returns a call ID and the agent polls `get_call` for progress and results. DialMCP is built by Datawizz Inc., the makers of Gamut. It is free during launch. ## Connect - Remote MCP endpoint: https://mcp.dialmcp.com/mcp - Transport: Streamable HTTP - Authentication: OAuth 2.1 with SMS verification - Remote clients do not need an install or API key. - Clients that only support local MCP servers can use the MIT-licensed `dialmcp-connector` stdio bridge: https://github.com/SkillfulAgents/dialmcp-connector ## Supported clients Any MCP client that supports remote Streamable HTTP servers with OAuth can connect. Setup guides are available for Gamut, Claude, ChatGPT connectors, Cursor, and Codex. - Documentation hub: https://dialmcp.com/docs - Installation and connection: https://dialmcp.com/docs/install - Hosted MCP server endpoint: https://dialmcp.com/docs/hosted - Client setup: https://dialmcp.com/docs/clients - ChatGPT MCP connector: https://dialmcp.com/docs/chatgpt - MCP server configuration examples: https://dialmcp.com/docs/configuration - Deploy an MCP server with Docker: https://dialmcp.com/docs/docker - MCP server commands and tool calls: https://dialmcp.com/docs/commands - OAuth: https://dialmcp.com/docs/oauth - Which voice AI APIs can call a cell phone: https://dialmcp.com/docs/voice-ai-apis - How to build an MCP server: https://dialmcp.com/blog/build-mcp-server - Remote MCP servers explained: https://dialmcp.com/blog/remote-mcp-servers - Best MCP servers for Claude: https://dialmcp.com/blog/best-mcp-servers - Best remote MCP servers: https://dialmcp.com/blog/best-remote-mcp-servers - MCP server tutorial (stdio to remote): https://dialmcp.com/blog/mcp-server-tutorial - How to create an MCP server in Python (SDK v2): https://dialmcp.com/blog/create-mcp-server-python - How to add an MCP server to Claude: https://dialmcp.com/blog/add-mcp-server-to-claude - Claude Code MCP setup: https://dialmcp.com/blog/claude-code-mcp - MCP tools, prompts, and resources: https://dialmcp.com/blog/mcp-prompts - How to build an AI voice agent: https://dialmcp.com/blog/how-to-build-an-ai-voice-agent - AI voice agents for healthcare scheduling: https://dialmcp.com/blog/ai-voice-agent-healthcare - Best AI voice agents: https://dialmcp.com/blog/best-ai-voice-agents - AI voice agents for small business: https://dialmcp.com/blog/ai-voice-agent-small-business ## Tools - `place_call` — start an outbound call with a destination number and stated objective; returns a call ID immediately. - `get_call` — fetch call status, progress, transcript, recording link, and structured resolution. - `end_call` — hang up an in-progress call. - `list_calls` — list recent calls and outcomes for the authenticated user. ## Safety and limits Safety controls are enforced server-side rather than left to the agent's instructions. Every call discloses that it is an AI assistant, who it is calling for, and that the call is recorded. Calls use the user's verified caller ID; caller-ID spoofing is not used. - US and Canada only. - Calls are permitted from 8:00 to 21:00 in the destination's local time. - One concurrent call, three calls per hour, and ten calls per day. - No more than two calls per day to the same destination. - Six-minute default duration and ten-minute hard cap. - Emergency services, premium-rate lines, and high-fraud ranges are blocked. - Permanent do-not-call opt-outs are enforced platform-wide. - Telemarketing, cold outreach, robocalling, surveys, lead generation, debt collection, and political outreach are prohibited.
