Coding Agents

Add phone calls and SMS to your coding agent. One config block — your agent can buy numbers, make calls, read texts, and manage voice AI, all through natural language.

Works with any MCP-compatible client: Claude Code, Cursor, Windsurf, Claude Desktop, and more.

Claude Code

Option A: MCP Server

$
claude mcp add agentphone -- npx -y agentphone-mcp

Then set your API key:

$
export AGENTPHONE_API_KEY=your_api_key_here

Option B: Skill (slash command)

$
npx skills add AgentPhone-AI/skills

$
export AGENTPHONE_API_KEY=your_api_key_here

Then use /agentphone in any conversation:

/agentphone buy a 415 number and create a support agent
/agentphone call +14155551234 and ask about their hours
/agentphone show me my recent SMS conversations

Cursor

Add to your Cursor MCP settings (Settings > MCP or ~/.cursor/mcp.json):

1
{
2
  "mcpServers": {
3
    "agentphone": {
4
      "command": "npx",
5
      "args": ["-y", "agentphone-mcp"],
6
      "env": {
7
        "AGENTPHONE_API_KEY": "your_api_key_here"
8
      }
9
    }
10
  }
11
}

Restart Cursor. In Composer or Chat, try:

“Create an agent and buy it a phone number, then call me at +14155551234 to test it.”

Windsurf

Add to your Windsurf MCP configuration:

1
{
2
  "mcpServers": {
3
    "agentphone": {
4
      "command": "npx",
5
      "args": ["-y", "agentphone-mcp"],
6
      "env": {
7
        "AGENTPHONE_API_KEY": "your_api_key_here"
8
      }
9
    }
10
  }
11
}

Claude Desktop

Add to your Claude Desktop config:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

1
{
2
  "mcpServers": {
3
    "agentphone": {
4
      "command": "npx",
5
      "args": ["-y", "agentphone-mcp"],
6
      "env": {
7
        "AGENTPHONE_API_KEY": "your_api_key_here"
8
      }
9
    }
10
  }
11
}

What your agent can do

Once configured, your coding agent has 26 phone tools:

Real-world examples

Customer research from your IDE

> Create an agent, buy it a number, then call these 5 restaurants
  and ask if they have availability for 8 people this Saturday:
  +14155551111, +14155552222, +14155553333, +14155554444, +14155555555
  Summarize what you find.

Test your app’s phone integration

> I just deployed a new IVR. Call +14155559999 and navigate through
  the menu — press 1 for sales, then ask about enterprise pricing.
  Tell me if anything sounds broken.

Quick SMS check while coding

> Show me any SMS messages that came in today on my agent's number.

Set up a phone agent for your project

> Read my project's README and create a voice agent that can answer
  questions about this codebase. Give it a phone number and set the
  greeting to "Hi, I'm the docs bot for [project name]."
