PlaceCall

PlaceCall

PlaceCall lets your agent call US businesses to handle reservations, gather information and get quotes. You get back the outcome and a transcript. First 250 calls free. Built by ex-Google Maps and Search developers.

curl -s -X POST https://api.voygr.tech/calls \

-H "X-API-Key: $PLACECALL_API_KEY" -H "Content-Type: application/json" \ -H "X-Client-Surface: gh-repo" \ -H "X-Client-Agent: ${CLAUDECODE:+claude-code}${CURSOR_AGENT:+cursor}${CODEX_SANDBOX:+codex}${GEMINI_CLI:+gemini-cli}" \ -H "X-Client-Version: placecall-skill/6.6.0" \ -d '{"target_phone":"+1XXXXXXXXXX","brief":"Call this restaurant and ask what time the kitchen closes tonight.","language":"en"}'

The raw API takes your key in the X-API-Key header. Get one at https://api.voygr.tech/checkout; it arrives by email. The plugins and MCP connectors below sign you in through a browser instead. An agent with no browser can sign you up by email code.

What PlaceCall does

Give PlaceCall a US number (or a list) and a task in plain English: an inquiry, a quote request or a booking. It dials, navigates IVRs and hold, and talks to the business.

No number? Describe the place instead, for example "a romantic restaurant in Chicago, Saturday 8pm". PlaceCall finds candidates, explains its picks and writes the call brief.

The bot reads only the brief. Put the full job in it: what to ask, who it's for, names, dates, party size, callback number, the outcome you want and how to wrap up.

What it handles

• Book, cancel or reschedule tables and appointments
• Verify info, follow up on orders, check stock, get quotes
• Contact many businesses at once
• Recommend the best venue, service or vendor when you don't have a number
• Report what happened, and raise a question mid-call if needed

What you get back

Every call returns a labelled outcome, the full transcript and the recording. A failed call comes back with its reason: dropped, busy, voicemail or a wrong number.

Install

The Claude Code, Codex and Cursor plugins carry the skill and the PlaceCall MCP server (https://api.voygr.tech/mcp). You sign in once in a browser; the first sign-in creates a PlaceCall account with free credits, so there is no key to copy. The claude.ai connector works the same way, and so does PlaceCall in the OpenAI plugin directory, which ChatGPT and Codex share. The directory listing carries the MCP server but not the skill. The skill-only routes (a copied skill, the Codex skill installer, OpenClaw) call the API with a key; see Get a key. A few options need a key on every route: switching off recording, changing the opening notice, canceling a call, and listing your calls.

Claude Code (recommended)

The plugin updates itself from this repo. Two commands install it, with no shell or git:

/plugin marketplace add voygr-tech/placecall

/plugin install placecall@placecall

For the Anthropic plugin directory, submit the `claude-directory` folder. It

uses the same MCP server and browser sign-in, with an MCP-only skill. The root marketplace retains the API-key instructions for clients that need API-only options.

Choose user scope ("Install for you") unless you want it confined to one repository. Then run /mcp, pick the placecall server and sign in. The skill answers to /placecall:placecall, and Claude uses it on its own when you ask to call someone.

Installed the plugin before 6.1.0? Run /plugin marketplace update placecall and restart Claude Code. A key you already exported keeps working with its account and credits; without one, sign in with /mcp.

Claude Code, without the plugin

git clone https://github.com/voygr-tech/placecall && cd placecall

./install.sh # copies skills/placecall/SKILL.md -> ~/.claude/skills/placecall/

`install.sh` only copies `skills/placecall/SKILL.md` into your skills dir (no

network, no other side effects); copying by hand works too. Skills load at startup, so start a new Claude Code session. A copy never updates itself; the plugin does.

Cowork

Use the Claude connector. Add it once as in claude.ai chat below, and it is there in Claude chat, Cowork and Claude Desktop. No key, no terminal.

The plugin also installs in Cowork (Customize > Plugins > Add marketplace, paste voygr-tech/placecall, Install). It adds the skill and connects the same server. Install one or the other; with both, your agent sees two PlaceCall servers offering the same tools.

Need one of the key-only options? Install the plugin instead of the connector and give the skill a key. Cowork has no terminal for the export in Get a key, and its Bash sandbox blocks our API until allowed, so put both in ~/.claude/settings.json and restart Cowork:

{

"env": { "PLACECALL_API_KEY": " " }, "sandbox": { "network": { "allowedDomains": ["api.voygr.tech"] } } }

env keeps the key across reboots; a desktop app never sees your shell. allowedDomains pre-allows api.voygr.tech; Claude Code pre-allows none, so without it the first call prompts for permission. If your organization sets strictAllowlist or allowManagedDomainsOnly, the call is blocked with no prompt (the "deep admin setting" people report).

The key sits in plaintext in that file, like the 600 env file in Get a key. chmod 600 ~/.claude/settings.json if you want matching permissions.

claude.ai chat

Works on every plan through a custom connector with sign-in.

Personal plans: Settings > Connectors > Add custom connector. Team/Enterprise: an Owner adds it once under Organization settings > Connectors, and each member signs in with their own PlaceCall account.

1. Name it PlaceCall, URL https://api.voygr.tech/mcp. Keep the sign-in setting Claude detects.
2. Add, then sign in with Google or email. The first sign-in accepts the Terms of Service and Privacy Policy and creates your account with free credits.
3. Allow access. PlaceCall appears in the chat's tools menu and always confirms before placing a call.

One API key for a whole workspace? Add the connector with No sign-in and a Request header x-api-key carrying your key. All calls then bill to that key.

ChatGPT

PlaceCall is in the ChatGPT plugin directory.

1. Open Plugins, search for PlaceCall and press + on the one by Voygr Tech, inc, or go straight to https://chatgpt.com/plugins?search=placecall.
2. Sign in with Google or email, then press Allow to let ChatGPT use your PlaceCall account. The first sign-in accepts the terms and creates your account with free credits.
3. In a chat, type @PlaceCall and ask for a call.

Added PlaceCall as a custom app before it was listed? Remove that custom app, so ChatGPT has one PlaceCall to choose.

If the directory listing isn't available to you, add PlaceCall as a custom app in ChatGPT on the web instead. Custom apps depend on your ChatGPT plan.

1. Open Plugins, then + > Create plugin > Create MCP App.
2. Name it PlaceCall, server URL https://api.voygr.tech/mcp, authentication OAuth. Leave the OAuth settings ChatGPT discovers as they are, accept the custom-app notice, and Create.
3. Sign in with Google or email. The first sign-in accepts the terms and creates your account with free credits.
4. In a chat, pick PlaceCall from the tools menu.

Any MCP client (Cursor, Windsurf, MCP Inspector, ...)

Point the client at https://api.voygr.tech/mcp (streamable HTTP transport). It is in the official MCP Registry as io.github.voygr-tech/placecall. Sign in with OAuth where your client supports it, or send your key on every request in either header:

X-API-Key: <your key>

or Authorization: Bearer .

Claude Code keeps its own MCP config (claude.ai connectors do not carry over), so add it there:

claude mcp add --transport http --scope user placecall https://api.voygr.tech/mcp

Then run /mcp, pick placecall and sign in. To use a key instead, add --header "X-API-Key: ". --scope user makes it available in every project. The plugin above is still the richer path for Claude Code: it adds the full skill to the four tools.

Codex

PlaceCall is in the OpenAI plugin directory. Type this inside Codex (not your shell):

/plugins

Open the OpenAI Curated tab, pick PlaceCall and choose Install plugin. Codex opens ChatGPT: press Connect, sign in and press Allow. Then start a new Codex session and type @PlaceCall.

Codex and ChatGPT share the directory, so a PlaceCall you add in ChatGPT (https://chatgpt.com/plugins?search=placecall) shows up in Codex as installed.

If Codex answers Unknown tool, open PlaceCall's page in ChatGPT's Plugins and check that its app is connected; press Connect if it is not. If @PlaceCall ends up in another phone-call app, remove that app.

The plugin from this repo

The directory listing has the MCP server only. The plugin in this repo, the same one as Claude Code's, also carries the PlaceCall skill. Install one or the other: with both, Codex has two sets of PlaceCall tools. Run these in your shell:

codex plugin marketplace add voygr-tech/placecall

codex plugin add placecall@placecall codex mcp login placecall

The last command opens the browser sign-in. If your Codex has no plugin command, update Codex or use the skill installer below.

To install only the skill and use a key, type this inside Codex (not your shell); $skill-installer is bundled with Codex:

$skill-installer install the skill at https://github.com/voygr-tech/placecall/tree/main/skills/placecall and name it placecall

It expects plain English, installs the skill and reports where it landed. No restart: $placecall works from your next turn.

If Codex does not understand the phrasing above, run the installer's script from a normal shell:

python3 ~/.codex/skills/.system/skill-installer/scripts/install-skill-from-github.py \

--url https://github.com/voygr-tech/placecall/tree/main/skills/placecall \ --name placecall

The installer refuses to overwrite: delete any existing placecall (or older callwright) skill in ~/.codex/skills first. Don't run install.sh on Codex; that script is for Claude Code.

The skill folder moved from skills/call to skills/placecall in October 2026; an install line that still says .../tree/main/skills/call finds nothing. An installed copy keeps working as $placecall. For newer versions, delete it and reinstall from the skills/placecall URL above.

On older Codex without $skill-installer, or on any Codex, paste this repo's AGENTS.md into your project's AGENTS.md.

Hermes Agent

One command. It prompts for the key, so nothing lands in your shell history:

hermes mcp add placecall --url https://api.voygr.tech/mcp/ --auth header

Keep the trailing slash on the URL. Answer Y to "Does this server require authentication?", paste the key at the masked prompt, and Y to enable all four tools. Hermes stores the key in ~/.hermes/.env (as MCP_PLACECALL_API_KEY) and writes only a ${...} reference into config.yaml. Verify with hermes mcp test placecall, then start a new session; tools load at session start.

Do not use the skill route on Hermes. Its scanner refuses hermes skills install placecall, because the skill sends an API key with curl to a non-loopback host; the MCP route has no shell and no env var in the request.

Gemini CLI

This repo is also a Gemini CLI extension: the skill plus the PlaceCall MCP server. Install it from your shell:

gemini extensions install https://github.com/voygr-tech/placecall

The install asks for your PlaceCall API key and keeps it in the system keychain (change it later with `gemini extens
