Installation

In SourceWeft

  1. Open volai in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/cz.volai%2Fvolai/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

volai

Czech telephony API and MCP for apps and AI agents - numbers, calls, SMS, voice agent. This plugin connects Codex and Claude Code to the volai MCP server (107 tools: numbers, calls, SMS, voice agents, webhooks, connected calendars and invoices) and bundles the full volai skill so Claude knows the API conventions (E.164 numbers, prices in Czech hellers, idempotency keys) without extra prompting.

Install

claude plugin marketplace add https://volai.cz/.claude-plugin/marketplace.jsonclaude plugin install volai@volai

Sign in with volai

The plugin uses OAuth. Connect the server, open the sign-in page, and approve access to your volai account. The consent page describes access to account data, voice agents, paid calls, SMS and number orders. Revoke access at any time under API and MCP in the volai portal.

For a direct MCP connection in Claude Code:

bash
claude mcp add --transport http volai https://volai.cz/mcp

Then use /mcp to authenticate. In Codex, add the remote MCP URL https://volai.cz/mcp and sign in. This archive includes both the Claude and Codex plugin manifests. Distribution through this project's own marketplace does not imply approval by either official directory.

API key alternative

Existing API keys remain supported. For a manual Claude Code connection:

bash
claude mcp add --transport http --header 'Authorization: Bearer vk_YOUR_KEY' volai https://volai.cz/mcp

The REST examples in examples/ read VOLAI_API_KEY:

export VOLAI_API_KEY=vk_YOUR_KEY

Get a key in the volai portal under API and MCP (https://volai.cz/en/api-and-mcp) after signing up at https://volai.cz/en/auth/signup. Treat the key like a password - anyone who has it can spend your credit (buy numbers, place calls, send SMS).

What you get

  • MCP server (https://volai.cz/mcp) - the same 107 tools documented at https://volai.cz/en/docs/mcp, authenticated through OAuth or an API key.
  • volai skill (skills/volai/SKILL.md) - the full API reference (authentication, conventions, endpoints, tool list) so Claude picks the right tool and field names without guessing.
  • Examples (examples/) - two small Node 20 scripts (send-sms.mjs, make-call.mjs) that call the REST API directly with fetch, no dependencies.

Try it

Once installed, just ask Claude Code things like:

  • "Send an SMS to +420777123456 saying the order is ready."
  • "Call me at +420777123456 and try being a cafe receptionist - I don't want to set up my own number or agent for this."
  • "List my last 10 calls and summarize them."

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
