Install

Get a free Deyaho account and top up minutes at https://app.deyaho.com/dashboard/mcp. That page also creates API keys (dy_mcp_...) for clients that use one.

Claude (claude.ai and Claude Desktop): Settings > Connectors > Add custom connector, paste https://mcp.deyaho.com/mcp, click Connect and sign in with your Deyaho account (OAuth, no key needed).

Claude Code:

claude mcp add --transport http deyaho-calls https://mcp.deyaho.com/mcp --header "Authorization: Bearer dy_mcp_YOUR_KEY"

Without the header, sign in from /mcp inside Claude Code.

Cursor (~/.cursor/mcp.json or .cursor/mcp.json):

{

"mcpServers": { "deyaho-calls": { "url": "https://mcp.deyaho.com/mcp", "headers": { "Authorization": "Bearer dy_mcp_YOUR_KEY" } } } }

ChatGPT: Settings > Apps & Connectors > Advanced settings, turn on developer mode, create a connector with https://mcp.deyaho.com/mcp and OAuth authentication.

Pricing

0.25 USD per connected minute, rounded up to the minute. Prepaid packs: 40 min = 10 USD, 100 min = 25 USD, 200 min = 50 USD (also in EUR and MXN). No monthly fee, no number to buy. A 3-minute call costs 0.57 USD.

Limits and compliance

• Max 4 minutes per call, 10 calls per day per key, one call at a time.
• Calling hours depend on call_purpose, local time of the destination: service calls Monday to Saturday 09:00-21:00; commercial calls Monday to Friday, Spain 09:00-21:00 and Mexico 09:00-19:00. No calls on Sundays or national holidays.
• Since 17 October 2026, commercial calls to Spain must come from a 400 number. Until Deyaho has one, calls to Spain are service calls; make_call returns commercial calls to Spain require a 400 number otherwise.
• Only the destinations above; emergency, premium-rate and toll-free numbers are blocked.
• At the start the agent says it is an AI (EU AI Act art. 50) and that the call is recorded, and only names the business you give it.
• Only call people who requested or agreed to be contacted (Spain: prior consent for commercial calls; Mexico: REPEP; United States and Canada: prior express consent). Never cold calls to purchased lists.
• Voice and data are processed in the EU. Recordings are deleted after 15 days; transcript, summary and collected data after 90 days.
