Dialyne

Dialyne — real phone calls in France for AI agents

Website: https://dialyne.com · MCP server: https://mcp.dialyne.com/mcp · API: https://api.dialyne.com · Dashboard: https://app.dialyne.com · Docs: https://dialyne.com/docs/ · For agents: https://dialyne.com/llms.txt

Dialyne gives an AI agent a phone line in France. The agent describes a task in plain language ("book a table for 4 on Friday around 8 pm for Martin"); Dialyne's voice agent calls the French number, introduces itself as the user's virtual assistant (an AI), navigates the phone menu, waits on hold, talks to the person, and returns a written result: outcome, summary and transcript.

This repository is the public showcase: MCP connection files for each client, an agent skill, examples and docs. The Dialyne service itself is hosted and closed-source; nothing here runs a server.

• 🇫🇷 French numbers (+33): landlines and mobiles. Calls are placed whenever the user asks, day or night; automatic retries (busy line, no answer) stay within 08:00–21:00 in the callee's time zone; a callback time the callee asks for is kept as they said it.
• 🤖 By default the agent says "Hello, this is Léa, 's virtual assistant" and answers yes if asked whether it is an AI (EU AI Act art. 50). The user can customise how it introduces itself; it never denies being an AI. No marketing, prospecting or mass calling.
• ☎️ Phone menus (voice and keypad), hold time, questions to your agent during the call, hand-over to a human.
• 📝 Text only: no audio is recorded or returned. Transcripts are deleted automatically (after 90 days, or sooner if the user chooses).

Connect

The server uses OAuth 2.1 (dynamic client registration, PKCE). Paste the URL; your client opens a Dialyne sign-in page the first time a tool is called. Agents without a browser can send an API key as Authorization: Bearer <key> instead. Never put a key in a URL.

Tools

Tool	What it does
place_phone_call	Calls a French number with a task in plain language; returns a call_id immediately (the call runs 1–10 min in the background). Optional language, scheduled_at, voice, idempotency_key.
get_call	Status and written result; waits up to 50 s for news (answered, on hold, question, transfer, end). Repeat until done=true.
answer_call_question	Relays the user's answer when the voice agent asks something during the call (within ~45 s).
hold_call_question	Asks the callee for one more minute when the user needs time to answer a pending question (only if the callee agrees; never more than 2 minutes per question).
transfer_call_to_user	Hands the live call over to the user's phone.
schedule_callback	Calls the same number again later with the same task.
cancel_call	Cancels a scheduled call or hangs up a live one.
list_calls	Past and scheduled calls, searchable.
get_account_balance	Minutes of conversation left and account limits.
configure_agent_identity	Reads or changes how the voice agent introduces itself (name, tone, opening line, answer to "who is calling?", AI mention in the opening). Name and tone change freely; any other change needs the user's explicit, logged acceptance of the warning it returns.
place_batch_calls	Places the same call to a list of French numbers (Pro and Enterprise plans, 100 numbers at most); returns a batch_id and one call_id per number. Never for marketing or mass calling.
get_batch_calls	Progress and results of a batch: counts by status, successes, refused numbers, and each call's outcome and summary.

Typical flow: place_phone_call → get_call(wait_seconds=25) until done → answer_call_question if a pending_question appears → report outcome and summary. Full reference: https://dialyne.com/docs/mcp

Example

User: Call Le Lys on 05 34 00 11 22 and book a table for 4 on Friday around 8 pm, name Martin. I prefer indoors.

Agent: place_phone_call(phone_number="+33534001122", task="Book a table for 4 on Friday around 8 pm for Martin. 7:30-9 pm is fine. Indoors preferred.") → get_call(...) → the restaurant asks "terrace or indoors?" → answer_call_question(call_id, "Indoors, please") → get_call(...)

Agent: Done: table for 4 on Friday at 7:45 pm, indoors, under Martin. 20:00 was full.

Code examples: curl, Python, TypeScript, n8n.

Rules built into the service

• Recommended identity by default: the agent introduces itself as the user's virtual assistant and says it is an AI whenever asked. The user can change this with configure_agent_identity; a change away from the recommended settings only applies after the user accepts a warning, which is logged, and the user is then responsible for those settings. One rule never changes: the agent never denies being an AI. Agents must show the warning to their user and never accept it on their behalf.
• Calls are placed whenever the user asks, day or night; automatic retries (busy line, no answer) stay within 08:00–21:00 in the callee's time zone; a callback time the callee asks for is kept as they said it.
• Only what French law forbids is refused: marketing, prospecting, surveys, mass calling (French Consumer Code art. L223-1 forbids phone canvassing of consumers without consent), threats, harassment and impersonation.
• Codes and card details: the user decides. Write a value as [secret: value] and Dialyne masks it in what it stores (card numbers are masked automatically); for a payment, prefer handing the call to the user.
• At most 5 calls per number per day across all customers; a person who asks not to be called again is blocked for every customer.
• Emergency, short and premium-rate numbers are refused.
