MCP support
Exposes WebVoice REST API functions as tools for MCP clients, including registration, account status, chat, audio, translation, and image generation.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
uvx webvoice-mcpWEBVOICE_API_KEYSecretWebVoice API key (wv_…). Optional until after webvoice_register_verify; required for chat/TTS/STT.WEBVOICE_BASE_URLREST API base URLLocal servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Configure Cursor
Option A — Agent registration via MCP (no browser)
- Add MCP without
WEBVOICE_API_KEYfirst (or use the register tools from any client). - Call
webvoice_register_send_codewith your email. - Read the OTP from email, then
webvoice_register_verifywith the code. - Response includes
api_key(once),onboarding.credits,onboarding.can_use_api, and optionalonboarding.solana(wallet +memo_codefor USDC/SOL top-up). - If
can_use_apiis true, use chat/TTS/STT immediately with welcome credits. - Set
WEBVOICE_API_KEYin MCP config and restart Cursor (optional Solana/PayPal top-up later).
REST equivalent: POST /api/v1/auth/send-code/ → POST /api/v1/auth/verify-code/ with create_api_key: true. See API docs.
Option B — Browser signup (human)
- Login — email OTP or Google (
/accounts/login/). New users get welcome + daily free credits. - API key — API dashboard → Create key → copy
wv_…(shown once). - Credits (optional) — Buy credits, Premium (PayPal), or Solana (send USDC/SOL with your personal memo from
webvoice_onboarding).
When balance is zero, MCP calls fail with insufficient credits; you receive an email with a recharge link.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
