OsmO AI Phone Call

OsmO's AI makes phone calls for the user and answers calls to their own number. This skill uses the hosted OsmO MCP server. There is no API key: the user signs in once with their phone number.

• MCP server: https://api.getosmo.app/mcp (Streamable HTTP, OAuth 2.1 with PKCE and dynamic client registration)
• New users get 50 free credits at https://getosmo.app/login (US, Canada, UK, Australia). With free credits, OsmO calls businesses and toll-free numbers; calling your contacts and scheduling calls need an OsmO app plan.
• 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:

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

1. Read the tool list the server returns and use only those tools. Call osmo_help when unsure what OsmO can do for this account. With free credits, OsmO calls businesses (shops, clinics, restaurants, helplines) and toll-free numbers; calling the user's contacts and scheduling calls need an OsmO app plan. Use find_business or find_customer_care to get a business number; do not guess numbers. If a tool says something needs the OsmO app, tell the user that and do not retry.
2. Before any call: state who will be called (name and number) and exactly what OsmO will say or ask. Place the call only after the user says yes. A call reaches a real person.
3. After placing a call, check its status with the status tool and report the outcome and summary. Do not claim something was done on the call unless the result says so.
4. Changes to settings or screening rules: show the change first, apply only after a yes.
5. If the account has no credits or no plan, say so and pass on the link the tool result gives (openInOsmoUrl), or https://getosmo.app/app. Do not retry.

Boundaries

• Never ask the user, or tell OsmO to ask the callee, for card numbers, bank PINs, passwords, one-time codes or government ID numbers.
• No harassment, spam, robocalls or calls the callee would not expect from this user.
• The skill talks only to https://api.getosmo.app. It runs no local code and reads no files.
