Security and access

Where requests go, whose account Claude uses, and what you control.

Server

mcp.synthflow.ai

On the developer’s own domain (synthflow.ai), not a third-party host. Claude sends requests here when it uses a tool.

Account

Your own Synthflow account

You sign in when you connect. Claude works through that account, so it reaches what the account can reach.

Control

You approve write tools

In Claude’s connector settings you can choose, tool by tool, whether Claude must ask before using it. Write tools are marked in the list above. See write tools

    Questions people ask

    What does the Synthflow connector do in Claude?

    Synthflow lets you build and operate AI voice agents that make and take phone calls. This connector brings your Synthflow workspace into your assistant, so you can create and configure voice agents; manage their actions (SMS, call transfers, bookings, custom API calls, and data extraction); organize knowledge bases, phone numbers, and contacts; review calls and analytics; and run agent simulations all from your favourite AI tool. It reads your workspace data and can make changes on your behalf; destructive actions like deletions are clearly marked and confirmed.

    Is the Synthflow connector official?

    It is made by Synthflow.ai and carries the Anthropic verified mark in Anthropic’s directory. This site is independent and lists it from the official directory.

    What is the Synthflow MCP server URL?

    https://mcp.synthflow.ai/mcp. It is a remote MCP server hosted at mcp.synthflow.ai. Paste it into Claude as a custom connector, or add it to Claude Code with: claude mcp add --transport http synthflow https://mcp.synthflow.ai/mcp

    How do I add Synthflow to Claude Code?

    Run "claude mcp add --transport http synthflow https://mcp.synthflow.ai/mcp" in your terminal, then start Claude Code, type /mcp, choose synthflow and sign in to Synthflow. Add "--scope user" to make it available in every project.

    Do I need a Synthflow account?

    Yes. You sign in to Synthflow when you connect it, and Claude works through that account.

    Can Claude change or delete my Synthflow data?

    Judging by tool names, 29 of its 62 tools can change data, including 10 that delete or remove things. The other 31 only read. In Claude you can choose, per tool, whether Claude must ask before using it.
