52 tools

• get_capabilities

  Start here to discover Patch actions, granted permissions, feature prerequisites and the next tools to call.

• place_call

  Place one real phone call FROM the selected outbound number (the authenticated user’s verified personal number by default) to accomplish a specific objective (book a table, ask a question, chase an order). A real-time voice agent handles the call, including automated phone menus…

• get_call

  Get the status and, once terminal, the structured resolution of a call started with place_call. Returns instantly by default. Pass wait_seconds (max 50) to have the server hold the request and return early on any status change — fewer round trips while a call is in progress…

• set_call_visibility

  Make a call owned by the authenticated user public or private. Calls are private by default. Only publish when the user explicitly asks: a public call exposes its objective, phone numbers, transcript, result and audio to anyone with its permanent, token-free listen_url…

• end_call

  End an in-progress call early. Patch requests disconnection by deleting the LiveKit room; a spoken farewell is not guaranteed. Check get_call for the resulting status. Use when the user changes their mind or the call is no longer needed. Available transcript snapshots are…

• list_phone_numbers

  List this account's phone numbers, active direction availability and default_number_id. Use number_id to select a source for place_call. Accepts calls:read or numbers:read; management settings and workspace_revision are included only with numbers:read. Does not expose agent…

• get_phone_number

  Read one owned number by number_id; omit it to inspect the default outbound number. Accepts calls:read or numbers:read. Number-management settings, revision, recovery deadline and workspace_revision require numbers:read. Does not place a call or expose agent instructions or…

• list_activity

  Read owned history newest first. kind=call (default) requires calls:read and returns call statuses, resolution summaries/outcomes and listen links. kind=test requires configuration:read and returns finished synthetic tests. kind=all requires both permissions. Pass next_cursor…

• get_account

  Read your profile, caller verification, revision, account defaults, setup progress and notices. Use update_account for profile changes and set_onboarding for setup state.

• update_account

  Update supplied profile, account-wide mode (standard or beta), language and voice defaults using the revision from get_account. Language and voice defaults require configuration permission. Internal system prompts are not exposed through MCP.

• set_onboarding

  Save only setup progress: choose inbound/outbound intent and mark the checklist checkout, complete or skipped. Checkout records progress only; this tool never opens payment, buys a plan or acquires a number.

• list_authorized_apps

  List applications authorized to access this account. These are distinct from external tools used by voice agents.

• revoke_authorized_app

  Disconnect an authorized application. Revoking the current application ends this MCP connection.

• list_agents

  Find the identifiers and revisions of your inbound and outbound agents.

• search_phone_numbers

  Find included US or Canadian numbers. Plus automatically prefers any unclaimed Patch number in the requested country, then falls back to area-code search. Pro plans use area-code search so the user can choose a number. Plus can use reuse_only without an area code to check its…

• claim_phone_number

  Acquire an offered number using your plan allowance. Reuse request_id after an interrupted response.

• get_number_claim

  Read provisioning progress for a number claim.

• update_phone_number

  Change a label, inbound/outbound availability or retention preference using the number revision. Enabling an unpublished direction activates its initial defaults; saved drafts and existing live settings are preserved.

• set_default_phone_number

  Choose the default outbound number using workspace_revision from get_phone_number.

• get_forwarding_carrier

  Suggest forwarding instructions for the verified personal number during inbound onboarding. Carrier lookups are cached for a day.

• get_forwarding_instructions

  Get carrier-specific steps for forwarding an existing phone to an owned Patch number. The user or carrier must activate forwarding; Patch cannot activate it remotely.

• get_agent

  Read active user-configurable settings and revision. Inbound includes editable greeting/instructions; outbound prompt text and Patch internal system prompts are not exposed. Settings are null until configured.

• update_agent

  Apply supplied settings directly to an agent for future calls using the revision from get_agent. Inbound greeting and instructions are editable. Outbound greeting and system instructions are not exposed or editable through MCP; supply per-call facts in place_call objective and…

• reset_agent

  Reset user-configurable agent settings to defaults for future calls. Removes active external connection assignments and requires connector permission when assignments exist.

• list_voices

  List voices for the current account mode. Change mode with update_account. Beta offers Phonic stock voices only; assign their ID using phonicVoice in update_agent. Standard uses voice and supports entitled custom voices.

• get_voice_preview

  Get a short-lived playable URL using provider_voice_id from list_voices, or Claudia's provider ID. Use the provider identity here; clone management uses voice_id. Built-in catalog voices already include sample URLs.

• create_voice_upload

  Create an expiring audio upload URL. PUT the file bytes there, then call create_voice with the upload_id and the user’s own-voice consent.

• create_voice

  Clone an uploaded sample of the user’s own voice. consent must represent the user’s explicit permission; never infer consent.

• rename_voice

  Rename one of your voice clones.

• delete_voice

  Delete your voice clone and its provider samples. A voice in an active call cannot be deleted.

• verify_voice

  Refresh provider verification status. If verification is still required, the user must complete the provider’s verification with support.

• list_connectors

  Read this account's saved voice-agent connections, authorization state and common providers. Returns setup_url for entering API keys or custom OAuth credentials on the website. Reads stored metadata only; does not contact providers, discover tools, assign agents or invoke…

• get_connector_tools

  Read the cached individual tool definitions for an owned connection. These functions are exposed separately to the voice agent on calls after set_agent_connectors assigns the connection. This read does not invoke them, refresh discovery or return credentials.

• create_connector

  Save a hosted voice-agent MCP connection requiring no credentials or standard browser OAuth, without contacting it or assigning agents. Never ask for or submit API keys, tokens, client secrets or credential-bearing URLs in chat. For API-key or custom OAuth setup, send the user…

• connect_connector

  Contact an owned connection to discover or refresh its individual voice-agent tools. May begin third-party OAuth and return authorization_url for the user to approve; never collect verification codes or credentials in chat. Does not invoke external tools or change agent…

• add_common_connector

  Create or return a managed Exa web-search connection using this account's existing paid entitlement. New connections are unassigned. Does not subscribe, charge, search, discover tools or change assignments. Next use connect_connector, inspect get_connector_tools and explicitly…

• set_agent_connectors

  Replace the external connections available to one active voice agent for future calls. Review get_connector_tools and obtain authorization for those capabilities first. Every discovered function is exposed individually to the voice agent; it may invoke those external actions…

• remove_connector

  Delete an owned connection and its saved credentials. Also revoke that connection from every assigned agent without applying unrelated settings. Requires configuration permission when an agent assignment is removed. Does not invoke external tools or revoke consent at the…

• list_test_scenarios

  List synthetic test scenarios and available responder outcomes. Tests use fictional data and never invoke connected external tools.

• start_agent_test

  Run one isolated synthetic conversation against the active agent settings at the supplied revision. Outbound supports preset or custom fictional scenarios; inbound requires custom_scenario. Uses LiveKit test rooms and may consume AI usage. Never dials a phone number, publishes…
