PlaceCall README

PlaceCall ☎️

The internet has APIs. The real world has phone numbers.

Give your agent a voice to call any US business, handle reservations, gather information, get quotes. Handles IVRs & hold. Returns outcome + transcript. First 250 calls free.

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}" \
  -d '{"target_phone":"+1XXXXXXXXXX","brief":"Call this restaurant and ask what time the kitchen closes tonight.","language":"en"}'

Authentication: the plugins and MCP connectors below sign you in in a browser, so there is no key to copy. The raw API, as above, takes your key in the X-API-Key header. Get one at https://api.voygr.tech/checkout - it arrives by email.

What PlaceCall does

Give PlaceCall a US number (or a list) and a task in plain English - from making an inquiry to requesting a quote or completing a booking - and it dials, navigates IVRs and hold, talks to a business, and returns a verified outcome + transcript + recording.

No number? Just describe the place: "a romantic restaurant in Chicago, Saturday 8pm". PlaceCall finds candidates, explains why it picked them, and writes the call brief for you.

Put the full job in the brief - what to ask, who it's for, names, dates, party size, callback number, and desired outcome. The agent reads the brief, then gets things done. If necessary - agents will ask questions mid-call.

What your agents can finally do

• 🍽️ Book / cancel / 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 exactly what happened, raise a question mid-call if needed

What you get back

Every call returns one of 17 verified outcomes, plus the full transcript and recording - including clear failure reasons like dropped calls, busy lines, voicemail, or wrong numbers.

Why developers use PlaceCall

Built for agents that need to get shit done. Built by developers who mapped the world - ex-Google Maps & Search team.

🎁 Your first 250 calls are on us.

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, and your first sign-in creates a PlaceCall account with free credits, so no key to copy. The claude.ai and ChatGPT connectors work the same way. The skill-only routes (a copied skill, the Codex skill installer, OpenClaw) call the API with a key instead, see Get a key. The Gemini CLI extension carries the MCP server too, but sends it your key rather than signing you in.

Signing in covers finding places, placing calls and following them. A few API options need a key on every route: switching off recording or changing the opening notice, cancelling a call, and listing your calls.

Claude Code (recommended)

Two commands, no shell, no git - and it auto-updates from this repo:

/plugin marketplace add voygr-tech/placecall
/plugin install placecall@placecall

Claude Code asks where to install it - choose user scope ("Install for you") unless you specifically want it confined to one repository. Then run /mcp, pick the placecall server and sign in. The skill answers to /placecall:placecall, and Claude reaches for it on its own whenever you ask to call someone.

Installed the plugin before 6.1.0? Run /plugin marketplace update placecall and restart Claude Code. If you already exported a key, you don't need to sign in: the skill keeps using your key, and your existing account and credits, for every call. Without a key, 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 is a tiny convenience script - it only copies skills/placecall/SKILL.md into your skills dir (no network, no other side effects); you can also copy it by hand. Then start a fresh Claude Code session (skills load at startup). Note that a copy never updates itself - if you want new skills and fixes as we ship them, prefer the plugin above.

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's guidance on writing briefs and following calls, and it connects the same PlaceCall server. Install one or the other, not both: with both, your agent sees two PlaceCall servers offering the same tools.

Need an option only the API has (switching off recording, a custom opening notice, cancelling a call)? Install the plugin rather than the connector, and give the skill a key. Do both of these in ~/.claude/settings.json: Cowork has no terminal, so the export in Get a key has nothing to run in, and the Bash sandbox blocks our API until you allow it:

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

Restart Cowork afterwards. Why each half matters:

• env puts the key somewhere that survives a reboot. Setting it in a shell does not reach a desktop app, which never sees that shell.
• allowedDomains pre-allows api.voygr.tech. Claude Code pre-allows no domains, so without this you get a permission prompt on the first call, and if your organisation sets strictAllowlist or allowManagedDomainsOnly the call is blocked outright with no prompt. That is the "deep admin setting" people hit.

Your key sits in plaintext in that file, same trust level as the 600 env file in Get a key. chmod 600 ~/.claude/settings.json if you want the file permissions to match.

claude.ai chat

Works on every plan via a custom connector with sign-in. No key to copy.

Setup. Personal plans: Settings > Connectors > Add custom connector. Team/Enterprise: an Owner adds it once under Organization settings > Connectors, and each member then 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. On first sign-in you accept the Terms of Service and Privacy Policy, and a PlaceCall account is created with free credits.
3. Allow access. PlaceCall appears in a chat's tools menu, where it can find places worth calling, place a call (it always confirms first), and fetch the result.

Prefer 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

Add PlaceCall as a custom app in ChatGPT on the web. 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. On first sign-in you accept the Terms of Service and Privacy Policy, and a PlaceCall account is created 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 listed 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 - either header works:

X-API-Key: <your key>

or Authorization: Bearer <your key>.

Claude Code keeps its own MCP config (it does not pick up claude.ai connectors), so add it there with one command:

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

Then run /mcp in Claude Code, pick placecall and sign in. To use a key instead, add --header "X-API-Key: <your key>". --scope user makes it available in every project. The plugin at the top of this page is still the richer path for Claude Code - it carries the full skill, not just the four tools.

Codex

The same plugin as Claude Code. 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. No key needed. If your Codex has no plugin command, update Codex or use the skill installer below.

Skill only, with a key. Type this inside Codex, not in your shell. $skill-installer is a system skill bundled with Codex, so there is nothing to set up first:

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

It is a skill rather than a command, so plain English works and is what it expects. It runs the install for you and reports where the skill landed. No restart needed, it is available on your next turn, and it answers to $placecall.

If the phrasing above is not understood, this is the script it runs, and you can run it yourself 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

Two things worth knowing. The installer refuses to overwrite, so if you already have a placecall (or older callwright) skill in ~/.codex/skills, delete it first or the install aborts. And don't run install.sh on Codex, that is the Claude Code path.

The skill folder moved from skills/call to skills/placecall in October 2026, so an install line that still says .../tree/main/skills/call no longer finds it. A copy you already installed keeps working and still answers to $placecall. To pick up newer versions, delete it and reinstall from the skills/placecall URL above.

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

Hermes Agent

One command, and it prompts for the key rather than taking it on the command line, so nothing lands in your shell history:

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

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, so the value is never in the config file. Verify with hermes mcp test placecall, then start a new session - tools load at session start.

Do not use the skill route on Hermes. hermes skills install placecall is refused by Hermes's own scanner: a skill that sends an API key with curl to any non-loopback host is a critical finding by that scanner's design, which is what our skill does on every call. MCP has no shell and no env var in the request, so the rule does not apply. The trailing slash on the URL matters.

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 extensions config placecall). Gemini hands that stored key to the MCP server only. The skill's curl commands run in your shell and read PLACECALL_API_KEY from there, so export it as well (see Get a key). If the key is exported but not stored, the MCP server picks it up from your environment too.

Cursor

This repo is also a Cursor plugin (.cursor-plugin/plugin.json): the skill plus the PlaceCall MCP server at https://api.voygr.tech/mcp, which signs you in with OAuth, so the plugin holds no key. To load it before it is in the Cursor Marketplace, clone it into Cursor's local plugins folder and run Developer: Reload Window:

git clone https://github.com/voygr-tech/placecall ~/.cursor/plugins/local/placecall

The skill's curl commands read PLACECALL_API_KEY from the environment Cursor's agent runs in. To send a key to the MCP server instead of signing in, see Any MCP client.

Any agent / plain shell

No install needed - the API is just HTTP. skills/placecall/SKILL.md is the full reference; a model with a shell tool can place calls straight from it.

No shell on your side? Assistants with their own computer (e.g. Meta Muse) integrate from this repo directly: paste the repo URL into the chat and ask it to use PlaceCall for phone calls. If it offers secure credential storage for the API key, use that - never paste the key into the chat itself.

Known to work this way: Meta Muse, OpenClaw (DeepSeek backend). Hermes needs the MCP route above rather than the skill. If you are an agent building this integration, send X-Client-Surface: <your-platform> on every request so we can see which surfaces need love.

Apify Store (no code, a whole list)

Have a list of businesses rather than an agent? PlaceCall on the Apify Store calls every business on it, asks the questions you set, and returns one row per call. No PlaceCall key: Apify runs it and bills it.

1. Open the Actor and press Try for free (you need an Apify account).
2. Bring the list: upload a CSV, link a Google Sheet, paste rows, or use another Actor's dataset, for example Google Maps results.
3. Type your questions, keep Check my list, don't call ticked and press Start. You see exactly what each business would be asked, for free.
4. Accept the PlaceCall terms, untick the check and start again.

$0.10 for each call that reaches a real conversation; unanswered calls, voicemail and busy lines are free. The first 10 calls on each Apify account are free, then a paid Apify plan is needed. Agents connected to the Apify MCP server can find and run it too.

Get a key (self-serve) and set it

Signed in through a plugin or connector? You need a key only for the options the MCP tools lack: switching off recording or changing the opening notice, cancelling a call, and listing your calls. The skill-only routes and the raw API need a key to place calls at all. Keys are self-serve - no need to contact anyone:

1. Open https://api.voygr.tech/checkout?src=gh-repo and click "Get free API key" (name + email).
2. The key arrives by email (it is never shown in the browser or API response). What a new key includes, and the current credit rates, are shown on the checkout page.
3. Lost the key? https://api.voygr.tech/recover emails you a new one.
4. Need more credits? Top up on the same https://api.voygr.tech/checkout?src=gh-repo page (Stripe-hosted payment).

Then set the key in your shell:

Quick way - just export it for the current session:

export PLACECALL_API_KEY="<your key>"

Nicer way - save it once (no echo to screen, 600 perms) and load it per session:

mkdir -p ~/.codex
read -rsp "PLACECALL_API_KEY: " KEY; echo
printf 'export PLACECALL_API_KEY=%q\n' "$KEY" > ~/.codex/placecall.env
chmod 600 ~/.codex/placecall.env
unset KEY
# then, in any new shell where you want to place calls:
source ~/.codex/placecall.env

No shell at all? A desktop app never sees your shell environment, so neither of the above reaches it. Put the key in the env block of ~/.claude/settings.json instead, which survives restarts. See the Cowork section, which also covers the sandbox domain allowlist you need there.

Verify (prints your quota, never the key):

curl -s -H "X-API-Key: $PLACECALL_API_KEY" https://api.voygr.tech/users/me

Never commit ~/.codex/placecall.env or paste the key into chat - keep it in the env var / the 600 file above.

Installed this before August 2026?

This project was called Callwright until 2026-08, and the repo lived at voygr-tech/callwright-skill. Two things to know:

• Your existing setup keeps working. install.sh copies the skill rather than linking it, so an older copy is frozen at whatever it was when you installed - the rename cannot break it. It also means it will never pick up new skills or fixes, which is the reason to migrate.
• To migrate, delete the old copy first. It is still a working phone skill, so leaving it in place gives your agent two of them and the routing between them is ambiguous. install.sh now warns you if it finds one.
  shCopy

  rm -rf ~/.claude/skills/callwright ~/.claude/skills/callwright-skill
  

  Then install the plugin above, and re-export your key under its new name: PLACECALL_API_KEY. The key itself is unchanged - only the variable is renamed, so no need to reissue anything.

If you previously installed a phone-call skill from someone else (e.g. ai-call-agent), remove or disable that too, for the same reason.

The one rule

Everything goes in the brief - the bot reads only your brief. Put every detail in it (what to ask, who you're calling for, names/dates/party size/callback number, how to wrap up). One endpoint, describe the task, done.

Good to know

• Two things draw on one credit balance: answered calls and answered place suggestions. Calls: successful ones are billed, and so are a call dropped after something was obtained and a call you cancel 30 seconds or more after the callee answered; a failed call where nothing was obtained (voicemail, hangup, no answer) costs nothing. Suggestions: 5 credits per answered POST /v1/places/suggest, nothing when it returns no cards or is refused. Both take a refundable hold at request time that is larger than the charge, so either can return 402 while your balance still looks sufficient for the charge alone (GET /users/me for your balance; rates and top-ups are self-serve at https://api.voygr.tech/checkout?src=gh-repo). The free tier is one shared pot: 250 free calls means 2,500 credits, and suggestions spend from the same 2,500.
• After a call completed, the outcome/transcript can populate a moment after the status flips - poll GET /calls/{id} until outcome_type is non-null.
• 13 language codes accepted (en, es, fr, de, hi, ru, pt, ja, it, nl, sr, tr, pl) plus auto (the default: the call runs in English and does not switch mid-call; send es for a call in Spanish). en is the most reliable; non-English is best-effort.
• Only call numbers you're authorized to - real calls ring real phones. US destinations only; by default every call opens with a notice that the line is recorded (in English and Spanish it also names PlaceCall). The optional disclosure and record_call fields change or switch off that opening; see the skill's "Opening notice" section.

Network access

The skill ships nothing that runs on its own. It is instructions your agent follows, either with the PlaceCall MCP tools a plugin connected or with curl in its own shell. Every request goes over HTTPS to one host: api.voygr.tech. Nothing is sent anywhere else.

• MCP server: the Claude Code, Codex and Cursor plugins and the Gemini CLI extension register https://api.voygr.tech/mcp. suggest_places sends your request in plain words and an optional location; place_call sends the number to dial, your brief and the language; get_call_result sends a call id; answer_question sends a call id, a question id and your answer.

• Calls: POST /calls sends the number to dial, your brief and the language. GET /calls, GET /calls/{id}, GET /calls/{id}/events (polled while a call runs), POST /calls/{id}/answer (your reply to a question the call agent asks mid-call), POST /calls/{id}/cancel, GET /calls/{id}/transcript-merged and GET /calls/{id}/recording follow and read it.

• Finding a place to call: POST /v1/places/suggest sends your request in plain words, plus the name and callback number when you give them.

• Account: GET /users/me, GET /v1/usage, GET /checkout/packs, GET /skills/{id}/manifest and PUT /users/me/limits.

What authenticates each request. On the MCP server, the Claude Code, Codex and Cursor plugins sign you in with OAuth, and your client sends the resulting access token, not a key. The Gemini CLI extension sends your key in the X-API-Key header instead. Every curl request carries your key in the X-API-Key header. Either way PLACECALL_API_KEY goes to api.voygr.tech and nowhere else. POST /calls also sends three headers that never affect auth or billing: an Idempotency-Key so a retry cannot dial twice, X-Client-Surface naming the listing these instructions came from, and X-Client-Agent naming the tool that placed the call (claude-code, cursor, codex or gemini-cli, worked out from which of CLAUDECODE, CURSOR_AGENT, CODEX_SANDBOX and GEMINI_CLI is set; only the name is sent, never a variable's value).

The only local file the skill reads is ~/.codex/placecall.env, your saved key, and only when PLACECALL_API_KEY is unset. install.sh makes no network calls. The checkout, recovery and docs links in this README are pages for you to open; the skill does not fetch them.

On our side, a call rings a real phone and is recorded. Recordings and transcripts are kept for 90 days. Security reports: SECURITY.md.
