Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@calldesktech-mcp Create a voice agent, publish it, and route my number to it."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An MCP server for the CallDeskTech API. Let Claude (or any MCP client) build, publish and operate voice agents: conversation flows, subflows, knowledge bases, phone-number routing, calls, batch calls and webhooks.
In CallDeskTech, open Settings → API Keys and create a key (cdk_live_…). It is shown once and is pinned to one workspace.
Add the server to your MCP client.

Start with flow_authoring_guide — it documents every node type, its params, edge rules and the gotchas (e.g. conversational nodes wait for the caller; knowledge bases must be attached to an agent).

Tools that cost money (place_call, run_batch_call) or delete data are annotated so clients can ask before running them.
create_agent → 2. publish_agent_version with a flow → 3. set_number_routing to point a number at the returned version id → 4. place_call to try it → 5. get_call for the transcript.
The key can only reach its own workspace and cannot create or revoke other keys. Revoke it any time in Settings → API Keys. Full API reference: https://calldesk-tech.fly.dev/docs.
