PlaceCall

What PlaceCall does

PlaceCall MCP server gives agents access to phone calls with US businesses. An agent can provide a business number and a plain-language brief describing the task, such as asking about kitchen hours, requesting a quote, or booking an appointment. The brief can include names, dates, party size, callback details, and the desired result.

If the caller does not have a number, PlaceCall can work from a description such as a type of venue, location, and time. It finds candidate businesses, explains the selection, and prepares a call brief. Calls can cover restaurant or appointment bookings, cancellations and rescheduling, order follow-ups, stock checks, information requests, and quotes. Multiple businesses can also be contacted.

The service reports one of 17 verified outcomes and includes the complete transcript and a recording. Failure results can distinguish situations such as a busy line, voicemail, dropped call, or incorrect number. If the agent needs information during the call, it can ask a question mid-call.

How it works

PlaceCall MCP server is exposed at https://api.voygr.tech/mcp using streamable HTTP. An MCP client connects to that endpoint, authenticates with OAuth where supported or sends an API key, and makes the available PlaceCall requests. The service then handles dialing, interactive voice response menus, and hold periods before returning the call result.

The brief is the main input for the task. It should state what to ask for, who the request concerns, relevant dates or quantities, and what counts as success. PlaceCall can ask for confirmation before placing a call in connector-based use. The raw API accepts a US target phone number, a brief, and a language value.

PlaceCall is suitable for the Communication category when an agent must reach a business that does not expose the needed operation through an online API.

Setup and configuration

For Claude Code, Codex, and Cursor, the repository provides plugins that include the MCP server and guidance. These routes support browser sign-in, creating an account and applying free credits on the first sign-in. The Claude Code plugin can be installed from the PlaceCall marketplace; Codex provides corresponding marketplace and MCP login commands.

Other MCP clients can point to the streamable HTTP URL. OAuth can be used when the client supports it. Key-based requests may send X-API-Key or Authorization: Bearer on each request. The raw API also uses PLACECALL_API_KEY through the X-API-Key header. The README states that the first 250 calls are free.

Claude.ai and ChatGPT can use custom connectors or apps with the same MCP endpoint. Gemini CLI carries the MCP server but uses an API key rather than browser sign-in. Claude Desktop can access it through the Claude connector.

Limitations and notes

PlaceCall MCP server is focused on US business phone calls. It does not replace a web or database integration for services that already expose the required operation through an API. Some options require an API key on every route, including disabling recording, changing the opening notice, cancelling a call, and listing calls.

The repository distinguishes the richer Claude Code plugin from a manually copied skill: the copied skill does not update automatically. Connector and plugin installations should not be combined when both expose the same PlaceCall tools, because the agent may see duplicate servers. Account terms, privacy acceptance, and authentication depend on the selected client route.
