Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Lets your AI agents call you when they need a decision, and hear your answer.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

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.
A standard MCP server (stdio, TypeScript) — no client-specific code anywhere, verified over the raw protocol against a non-Claude client identity.
(The app + backend live in a separate repo.)
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.
Homebrew (macOS and Linux):
brew tap paigy-ai/mcp https://github.com/paigy-ai/mcp
brew trust paigy-ai/mcp brew install paigy
(`brew trust` is how current Homebrew opts in to a tap outside homebrew-core.)
Installs the server and its commands (paigy-mcp, paigy-listen, paigy-mcp-onboard, ...). Point your MCP client at paigy-mcp, then run paigy-mcp-onboard once to pair your phone.
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= 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.
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):
| You need… | Use | Answer comes back as |
|---|---|---|
| Yes/No or Approve/Deny | select:"confirm" (confirmStyle:"approve" for Approve/Deny) | {kind:"confirm", approved} |
| Pick one of several | options + select:"one" | {kind:"option", optionId} |
| Pick several | options + select:"many" | {kind:"multi", optionIds} |
| Rank / order a subset | options + select:"rank" | {kind:"ranked", optionIds} |
| A visual choice | options with an html or image preview | one of the above |
| An open-ended reply | no options | {kind:"text", text} |
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.
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:
hooks/hooks.json, wired by the plugin; nothing to set up.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.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.
