How do I use calldesktech-mcp?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. 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.

calldesktech-mcp

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.

Setup

Hosted (recommended): no install, no API key. Add https://calldesk.tech/mcp as a remote MCP server. Your browser opens, you sign in, pick a workspace and click Allow.

claude mcp add --transport http calldesktech https://calldesk.tech/mcp

Local (API key). For clients that cannot use the hosted server, run this package over stdio with a key from Settings → API Keys (cdk_live_…, shown once, pinned to one workspace):

claude mcp add calldesktech --env CALLDESK_API_KEY=cdk_live_... -- npx -y calldesktech-mcp

Variable	Required	Default
`CALLDESK_API_KEY`	yes (local only)	—
`CALLDESK_BASE_URL`	no	`https://calldesk.tech/api/v1`

Tools

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).

Area	Tools
Account	`whoami` `account_overview`
Agents	`list_agents` `list_agent_templates` `create_agent_from_template` `create_agent` `get_agent` `rename_agent` `delete_agent` `list_agent_versions` `publish_agent_version`
Subflows	`list_subflows` `create_subflow` `get_subflow` `update_subflow` `delete_subflow`
Knowledge	`list_knowledge_bases` `create_knowledge_base` `get_knowledge_base` `update_knowledge_base` `add_knowledge_items` `list_knowledge_items` `delete_knowledge_base`
Numbers & calls	`list_phone_numbers` `set_number_routing` `list_agent_environments` `promote_agent_environment` `place_call` `list_calls` `get_call`
Contacts	`list_contacts`
Batch calls	`list_batch_calls` `create_batch_call` `get_batch_call` `run_batch_call`
Webhooks	`list_webhooks` `create_webhook` `get_webhook` `update_webhook` `test_webhook` `delete_webhook`
Analytics	`get_analytics` `get_qa_overview`

Tools that cost money (place_call, run_batch_call) or delete data are annotated so clients can ask before running them.

Typical workflow

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.

Security

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.
