OsmO AI Receptionist

OsmO answers calls to the user's own phone number. Its AI receptionist talks to each caller, screens spam, takes the message or booking request, follows the user's rules, and sends a summary. This skill lets the user run that receptionist from their AI app through the hosted OsmO MCP server.

MCP server: https://api.getosmo.app/mcp (Streamable HTTP, OAuth 2.1; no API key)
Setup: install the OsmO app (https://getosmo.app/app), choose a plan, and turn on call forwarding on the user's number. The receptionist only answers calls once forwarding is on.
To place outgoing calls instead, use the osmo-phone-calls skill.
Terms: https://getosmo.app/terms · Privacy: https://getosmo.app/privacy

Connect (once)

If the osmo MCP tools are not available yet, tell the user to add the server and sign in. Every client below uses the same URL and the same browser sign-in.

Claude Code

claude mcp add --transport http osmo https://api.getosmo.app/mcp

then type /mcp inside Claude Code and sign in.

Codex

codex mcp add osmo --url https://api.getosmo.app/mcp
codex mcp login osmo

OpenClaw

openclaw mcp set osmo '{"url":"https://api.getosmo.app/mcp","transport":"streamable-http","auth":"oauth"}'
openclaw mcp login osmo

Hermes (~/.hermes/config.yaml), then hermes mcp login osmo:

yaml

mcp_servers:
  osmo:
    url: "https://api.getosmo.app/mcp"
    auth: oauth

Sign-in opens https://api.getosmo.app/mcp/oauth/connect in the browser. The user enters their phone number and a one-time code there. Never ask for that code in chat, and never store or repeat it.

How to use it

Read the tool list the server returns and use only those tools. Call osmo_help when unsure what this account can do.
"Who called?" / "What did I miss?": list recent calls, then open the ones that matter with get_call. Lead with what each caller wanted and anything urgent.
Greeting and receptionist settings: read them first (get_assistant, get_settings), show the exact change, and apply it only after the user says yes.
Rules for callers (put this person through, take a message from that company, block a number): read the current rules (list_rules), show the new or changed rule, apply on a yes.
Bookings: list_bookings shows booking requests callers left.
Not answering yet? If the account has no recent calls, check the plan with get_account_status, then get the user's carrier forwarding codes from osmo_support (topic forwarding). Do not guess carrier codes.

Boundaries

Never ask for card numbers, bank PINs, passwords, one-time codes or government ID numbers.
Show call details only to the signed-in account owner. Do not read out other people's numbers beyond what the tool returns.
The skill talks only to https://api.getosmo.app. It runs no local code and reads no files.
