This plugin links Claude Code to Synthflow, a platform for building and running AI voice agents that handle phone calls, through Synthflow's hosted MCP server. It adds two skills: one that audits recent calls made by a voice agent for problems, and one that reviews a voice-agent prompt before it goes live. It also bundles a documentation-search connector that works without any sign-in. Setup can use either Anthropic's official Synthflow connector or the plugin's own bundled MCP server, authenticated via OAuth or an API key. Because Synthflow operates separate regional endpoints, the configured MCP URL must match the user's workspace region for the connection to work.
About the service
Synthflow is a voice AI agent platform aimed at enterprises that lets businesses design, deploy, and manage AI agents that answer or place phone calls. According to the homepage, it provides its own telephony infrastructure, a visual flow builder, a testing environment, call monitoring, and integrations with CRM, ERP, and other business systems, and it is positioned for use cases such as customer service, appointment booking, lead qualification, and call routing across industries like healthcare, retail, and financial services.
What you can do with synthflow
- Run the call-review skill to audit the most recent calls handled by an agent against a checklist covering unresolved outcomes, repetition, dropped calls, and compliance concerns
- Run the prompt-review skill to check a voice-agent prompt before deployment for contradictions, missing context, tool alignment, escalation gaps, and compliance or regression risk
- Search Synthflow's official documentation through a bundled docs connector that requires no authentication
- Connect either through Anthropic's official Synthflow connector or the plugin's bundled MCP server, using OAuth sign-in or an API key for headless/CI environments
- Select the correct regional MCP endpoint (Global, US, or EU) to match the workspace, when not using the official connector
