Anthropic
Claude, Claude Code, and Cowork can all manage your Synthflow workspace from a conversation. Describe what you want in plain language, and Claude can create agents, review calls, build knowledge bases, and run tests without you opening the Synthflow dashboard.
Setup has one required step and one optional step:
- Connector: connects Claude to your workspace through the Synthflow MCP server. This gives Claude every Synthflow tool.
- Plugin (optional): teaches Claude two review workflows, one for recent calls and one for prompts before you publish. It adds no workspace tools of its own.
What you can do

Ask Claude to:
- Build and update agents: Create agents, draft and refine prompts, publish drafts, and compare versions before you go live.
- Manage calls: Place test calls, review recent calls, and surface summaries or negative-sentiment moments when you ask.
- Manage knowledge: Create knowledge bases, add items from files or URLs, and attach them to the agents that should use them.
- Run actions and simulations: Scaffold and test actions, then run simulations to validate behavior before launch.
Claude groups the tools into read-only actions that look things up and write and delete actions that change your workspace. You choose whether each group runs automatically or waits for your approval. Keep write and delete actions behind approval. Changes and guardrails lists which tools take effect immediately.
Connector
You sign in with your Synthflow account, so there is no API key to copy. For CI and scheduled runs, see API key authentication.
Claude website, desktop app, mobile app, or Cowork
Turn on the Synthflow connector in Claude, then sign in to Synthflow and pick your workspace. Region selection happens during sign-in, so you do not choose a server URL.
Claude Code
Add the server with the URL for your region, then run /mcp, select synthflow, and sign in:
You are redirected to Synthflow to log in, where you select the workspace you want to manage.

After you select the workspace, select Allow access on the next screen. You can then start prompting.
Plugin
The Synthflow plugin is listed in the Claude marketplace and is verified by Anthropic. It adds two skills that Claude loads when your request matches, so you do not name them:
- Call review checks an agent’s recent calls for unresolved outcomes, repetition, drop-offs, and compliance risks, and reports flagged calls with transcript evidence.
- Prompt review checks a prompt before you publish for contradictions, missing context, action mismatches, escalation gaps, and regression risk compared to the live version.
Install it from the marketplace listing. In Claude Code, you can also run /plugin, open Discover, and search for Synthflow.
Connect the connector first. The plugin uses the connector’s sign-in, so you do not sign in again.
Example prompts
With the plugin installed, these requests trigger its review workflows. The MCP Server page has more example prompts for reporting, testing, and debugging.
Security considerations
Call transcripts, knowledge base documents, and fetched web pages can contain text that tries to steer Claude into an unintended action, known as prompt injection. Keep write and delete tools behind approval and review each call. Changes and guardrails covers the safeguards on the Synthflow side.
FAQ
Do I need the plugin?
No. The connector gives Claude every Synthflow tool. The plugin only adds the call review and prompt review workflows on top. Installing both does not give Claude duplicate tools.
Can I install the plugin without the connector?
Yes, but only for workspaces in the Global region. The plugin includes its own connection to the Global server, which you sign in to with /mcp in Claude Code. For a US or EU workspace, connect the connector and ignore the plugin’s unauthenticated Global entry.
How does the plugin get updates?
New Synthflow workspace tools appear automatically because they come from the hosted server, not the plugin package. Skill and configuration updates ship as new plugin versions through the marketplace.
Can I use this in CI or headless runs?
Yes, with an API key. The official connector needs a browser sign-in, so for CI and scheduled jobs add the server with a Synthflow API key in the Authorization header. API key authentication has the command.
Why do tool calls fail with 'workspace_id is not accessible'?
Claude targeted a workspace outside your connection, usually by guessing an ID. Ask Claude which workspace it is connected to and retry. Workspace scope explains how to switch workspaces.
How is this different from Aurora?
How is this different from MCP Connectors?
MCP Connectors let a voice agent call tools on an external server during a live call. Claude and Claude Code are the opposite direction: they call tools to manage your Synthflow workspace.
How is model usage billed?
Claude and Claude Code run in your own Anthropic account, so model and subscription charges are billed by Anthropic according to your plan. Synthflow bills only for the workspace usage your actions generate, such as calls, under your existing Synthflow plan.
