MCP

Paigy — MCP server

A voice inbox for your AI agents. When an agent needs your input — mid-task, blocked, or done with something long-running — it can place an actual phone call and read the question aloud, text, push, or ring your phone with a banner, so you can reply by voice instead of babysitting a terminal.

Without Paigy, a long agent session means one of two bad options: sit and watch the terminal so you don't miss the moment it needs you, or walk away and come back to a task that stalled an hour ago waiting on a question you never saw. Paigy closes that gap — the moment your agent actually needs a decision, your phone gets pulled into the loop with the level of urgency that matches the moment (a silent inbox card, a quiet push, a banner, or a real ringing call), so you find out immediately instead of on your next check-in. Answer by voice or text and the reply lands back with the agent exactly like any other tool response, so it just continues — no copy-pasting, no reopening the terminal. It also pairs with the native Paigy iOS app, so a call rings through like a real phone call (CallKit) even when your phone is locked, and you can glance at or reply to anything from the lock screen.

Works with

A standard MCP server (stdio, TypeScript) — no client-specific code anywhere, verified over the raw protocol against a non-Claude client identity.

• Claude Code (this repo is also the plugin + marketplace for it)
• Codex CLI
• Gemini CLI
• Any other MCP client via standard config: Cline, Continue.dev, Zed, Cursor, Goose, mcphost — including local-model setups over Ollama, LM Studio, or llama.cpp

(The app + backend live in a separate repo.)

Install

One line, any terminal — detects your agents (Claude Code, Codex, Antigravity), wires Paigy into each, and pairs your phone once. Prints every command before running it; --dry-run shows the plan:

curl -fsSL https://paigy.ai/install | sh

Prefer to do it by hand? Pick your client below.

Claude Code (plugin — easiest path on Claude):

/plugin marketplace add paigy-ai/mcp
/plugin install paigy

Connects automatically; the first time an agent uses it while unpaired, it'll prompt you to pair — run /paigy-onboard (opens your browser to approve).

Claude Desktop (MCPB bundle — no terminal needed): download paigy.mcpb, then in Claude Desktop open Settings → Extensions and drag the file in (or double-click it). Ask Claude to "pair with Paigy" — it runs pairing itself and shows a code to approve on your phone. Also on Smithery.

Codex CLI:

codex plugin marketplace add paigy-ai/mcp --ref main
codex plugin add paigy@paigy-ai
npx -y -p @paigy/mcp@latest paigy-mcp-onboard

The plugin configures the Paigy MCP server and includes guidance for calls, replies, and callbacks. Start a new Codex session after installation.

Codex CLI — direct MCP fallback:

codex mcp add paigy -- npx -y @paigy/mcp@latest

Then forward Codex's thread id into the server, so each Codex conversation gets its own Paigy identity — Codex builds the MCP server's environment from a fixed allow-list, so a variable it isn't told to pass never reaches us. Add this line under [mcp_servers.paigy] in ~/.codex/config.toml (paigy-harness setup does it for you):

env_vars = ["CODEX_THREAD_ID", "CODEX_SESSION_ID"]

(Don't pass it as a -c override on mcp add — that lands before the block is written and Codex rejects the half-table with "invalid transport", writing nothing.)

Gemini CLI:

gemini mcp add -s user paigy npx -y @paigy/mcp@latest

Any other MCP client (Cline, Continue.dev, Zed, Cursor, or a CLI that takes the standard MCP JSON config directly) — most GUI clients take this in their MCP settings (Cline: cline_mcp_settings.json; Continue: ~/.continue/config.json):

{
  "mcpServers": {
    "paigy": {
      "command": "npx",
      "args": ["-y", "@paigy/mcp@latest"]
    }
  }
}

Then pair your phone:

npx -y -p @paigy/mcp@latest paigy-mcp-onboard

Each session hatches its own identity automatically the first time it reaches Paigy — no agent name to set or match. (Set PAIGY_AGENT=<name> only if you deliberately want a client to always speak as one fixed named identity; then run onboard with the same name.) Approve on your phone, then sign in at paigy.ai to start receiving messages.

Heads-up for smaller/local models: the tool descriptions ask the agent to pick between a few answer shapes (confirm, options, free text) based on context — Claude follows this reliably; smaller local models may be less consistent about it. Free text always works as a fallback.

Choosing how the user answers

notify_user should ask in the shape that's fastest to answer — don't leave a decision as free text. Pick with select (and options):

confirm is answerable straight from the banner (Yes/No or Approve/Deny buttons). Other paiges get banner actions See Options · Hear them · Remind me later.

urgency is a request, not a guarantee — the user's account settings can cap it lower. Four levels, low to high: "inbox" (silent, sits in the inbox), "push" (a quiet passive notification, no sound), "banner" (a time-sensitive lock-screen banner with sound), "call" (rings the phone — use only when you genuinely need the user in the moment).

If you're about to start something long-running or blocking — the kind of thing where the user would otherwise sit and wait on you — mention once, in passing, that you can text or call them when it's done or if you hit a blocker. Don't offer it for quick tasks, and don't repeat the offer once they've answered.

Stalled work (automatic, no setup)

When a session stops and its agent owns Paigy Goals with no progress for three days, a Stop hook holds the stop once a day and lists them, so the agent updates, finishes or cancels each before it goes quiet. It runs paigy-stalled from @paigy/mcp (0.40.15 or later) and is silent otherwise: nothing stalled, a stop already being continued by a hook, a reminder already given that day, or any error. One script, the same hook in each harness's plugin:

• Claude Code — hooks/hooks.json, wired by the plugin; nothing to set up.
• Codex CLI — plugins/paigy/hooks/hooks.json, wired by the Codex plugin. Codex runs a plugin's hooks only after you trust them: review and trust the Paigy hook when Codex asks.
• Any other harness with a Claude-style Stop hook — register npx -y -p @paigy/mcp@latest paigy-stalled as the Stop command. It reads the hook's JSON (session_id, stop_hook_active) on stdin and prints {"decision":"block","reason":…}.

Hosts with no hooks still get the list: check_replies (which the server's instructions tell every agent to call on startup and after a wake) returns it under stalled, and paigy-listen carries it in the work it hands a session it wakes.
