Part of the StudioMeyer MCP Stack — Built in Mallorca 🌴 · ⭐ if you use it

A note from us

We have been building tools and systems for ourselves for the past two years. The fact that this repo is small and has few stars is not because it is new. It is because we only just decided to share what we have built. It is not a fresh experiment, it is a long story with a recent commit.

We love building things and sharing them. We do not love social media tactics, growth hacks, or chasing stars and followers. So this repo is small. The code is real, it gets used, issues get answered. Judge for yourself.

If it helps you, sharing, testing, and feedback help us. If it could be better, an issue is more useful. If you build something with it, tell us at hello@studiomeyer.io. That genuinely makes our day.

From a small studio in Palma de Mallorca.

Why

Managing email, calendar, messaging, search, and image generation from an AI assistant usually means five to six separate MCP servers, each with its own install, OAuth dance, and API keys. This bundles all of it into one server that runs on your laptop.

Everything stays local. Your credentials live in ~/.personal-suite/config.json with 0600 permissions and AES-256-GCM encryption at rest. The only data that ever leaves your machine is the direct API call to the provider you configured. No signup, no backend, no tenant database.

Bring your own keys (BYOK) for Brave, Exa, Tavily, OpenAI, Gemini, and so on. Messaging uses your own bot tokens (BotFather for Telegram, Discord developer portal, Slack app, etc.). Email uses Gmail/Outlook OAuth or plain IMAP with auto-discovery for 30,000+ providers.

Quick Start

# Claude Desktop: add to claude_desktop_config.json
{
  "mcpServers": {
    "personal-suite": {
      "command": "npx",
      "args": ["-y", "mcp-personal-suite"]
    }
  }
}

# Claude Code
claude mcp add personal-suite -- npx -y mcp-personal-suite

# Cursor: same stdio command as Claude

Then in chat:

"What's configured?"                         → suite_status
"Show me the quickstart guide"               → suite_guide
"Set up email for info@example.com"          → suite_setup (module: email)
"What's on my calendar today?"               → calendar_list_events
"Send a Telegram to the team"                → channel_send

First-time setup wizard (optional, for Google OAuth):

npx mcp-personal-suite setup

49 Tools, 6 Modules

Email — email_* (15 tools)

Gmail OAuth2, Outlook OAuth2, generic IMAP/SMTP. Auto-discovery for 30K+ providers (Gmail, Outlook, Yahoo, iCloud, WEB.DE, GMX, T-Online, mailbox.org, Posteo, IONOS, Strato, Fastmail, ProtonMail Bridge, and many more). Attachments up to 25 MB with path-traversal protection.

email_status    email_setup       email_auth       email_list       email_read
email_send      email_reply       email_forward    email_search     email_threads
email_move      email_mark_read   email_mark_unread  email_delete   email_folders

Calendar — calendar_* (11 tools)

Google Calendar (OAuth2) plus CalDAV (Apple iCloud, Nextcloud, mailbox.org, Posteo, Radicale, any CalDAV server). Events, availability, conflict detection, Meet links, daily summaries. Provider-transparent: same tools for both.

calendar_status            calendar_list_events         calendar_get_event
calendar_create_event      calendar_update_event        calendar_delete_event
calendar_search_events     calendar_list_calendars      calendar_check_availability
calendar_upcoming          calendar_daily_summary

Messaging — channel_* (8 tools)

Telegram (grammy), Discord (discord.js), Slack (@slack/bolt), WhatsApp (Baileys). Bring your own bot tokens. Send, receive, broadcast, history.

Heads-up on WhatsApp: Baileys is an unofficial reverse-engineered client. It works but carries supply-chain risk and can break whenever WhatsApp changes its protocol. For anything production-critical, use the official WhatsApp Business API (WABA) instead. Baileys is fine for personal/tinkering use.

channel_status    channel_send       channel_receive     channel_list
channel_connect   channel_disconnect channel_broadcast   channel_history

Search — search_* (7 tools)

Multi-provider gateway (BYOK): SearXNG (self-hosted), Brave, Exa (neural), Tavily (research with citations). Web, news, images, deep research, semantic, code context.

search_web      search_news          search_images   search_deep
search_semantic search_code_context  search_research

Image — image_* (3 tools)

BYOK image generation: OpenAI DALL-E 3, Flux via fal.ai (photorealistic), Google Gemini Imagen 3 (product shots). Auto-routing by prompt type.

image_generate   image_edit   image_download

System — suite_* (5 tools)

Onboarding, status, setup wizard, health checks, embedded documentation, GDPR delete (per-module or complete wipe).

suite_status   suite_setup   suite_health   suite_guide   suite_delete

Config

Credentials live in a single JSON file:

• macOS / Linux: ~/.personal-suite/config.json
• Windows: %USERPROFILE%\.personal-suite\config.json

Permissions are forced to 0600 (owner read/write only). Sensitive fields (passwords, tokens, secrets, API keys) are encrypted with AES-256-GCM before being written. The encryption key is auto-generated in ~/.personal-suite/.key on first run, or you can provide your own via the CREDENTIAL_ENCRYPTION_KEY environment variable (32 bytes, base64).

Nothing ever leaves your machine except the direct API calls you make to the providers you explicitly configure.

Privacy

• No signup, no account, no telemetry.
• No outbound requests until you configure a module.
• Credentials encrypted at rest, file mode 0600.
• suite_delete(module: "all", confirm: true) wipes everything.
• MIT licensed. Read the source. Fork it if you want.

Development

git clone https://github.com/studiomeyer-io/mcp-personal-suite.git
cd mcp-personal-suite
npm install
npm run build
npm test             # ~400 tests, runs in under 5s
npm run dev          # watch-mode stdio
npm run start:http   # HTTP transport on :5120

HTTP Transport (self-hosted)

If you want a long-running server for multiple clients on your LAN:

mcp-personal-suite --http --port=5120

Point your MCP client at http://localhost:5120/mcp. Streamable HTTP with session management. Bind behind your own reverse proxy if you expose it beyond localhost.

Security defaults (HTTP mode):

• MCP_ALLOWED_ORIGINS — comma-separated origin whitelist for browser-based MCP clients. Unset means no cross-origin requests accepted (safest). Example: MCP_ALLOWED_ORIGINS=http://localhost:3000,https://my-client.example.com.
• MCP_MAX_SESSIONS — cap on concurrent sessions (default 100). Returns 503 Retry-After: 60 beyond the limit.
• MCP_HOST — bind address (default 127.0.0.1). Change to 0.0.0.0 only if you actually want to expose the server on the network.

Docker

docker build -t personal-suite .
docker run -d --network host \
  -v $HOME/.personal-suite:/home/node/.personal-suite \
  -e MCP_HTTP=1 -e MCP_PORT=5120 \
  personal-suite

Tech

• TypeScript strict, no any, no circular deps
• @modelcontextprotocol/sdk@^1.26.0
• imapflow (async IMAP with auto-reconnect), nodemailer (SMTP)
• googleapis (Gmail + Calendar OAuth)
• ts-caldav (Apple iCloud, Nextcloud, Radicale)
• grammy, discord.js, @slack/bolt, @whiskeysockets/baileys
• vitest for tests, stdio + Streamable HTTP dual transport
