Category & Scope
Tools & Capabilities Breakdown
Standard Vocal MCP Tools (6)
list_agents
Lists the assistants on the account (id, name, model, voice, transcriber) — the entry point to find an `assistantId`.
deploy_agent
One tool = one full vertical deployment. `deploy_agent(vertical: elagueur\
run_eval
The agent tests itself.** Fetches the live system prompt, simulates N scripted scenarios against the configured LLM, scores behavior (close speed, no price quoting, spelled digit confirmation, urgency priority, solicitation refusal), returns a `/100` grade with PASS / WARN / FAIL. No audio, no bill…
audio_forensics
Downloads the 3 recording tracks of a call (mono / customer / assistant), runs RMS-per-window analysis, and **locates the noise source**. Automates the exact manual investigation that found a "computer noise" issue was injected downstream of the caller's mic, not in Vapi.
prompt_diff
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Standard Vocal MCP is categorized under Conversational AI and uses a local stdio subprocess. In contrast, Moxie Docs MCP belongs to Knowledge & Memory using local stdio subprocess. Select Standard Vocal MCP when you need capabilities focused on conversational ai and Moxie Docs MCP when you require tools for knowledge & memory.
Prompts as code. `snapshot` captures the live prompt into local history, `diff` compares two versions, `rollback` pushes an old prompt back to Vapi.
regression_gate
CI for prompts.** Runs `run_eval` and blocks the update if the score regressed vs the stored baseline. Returns allow/deny with the reason.
