Quick answer
StackPicks Connect is a unified MCP gateway: instead of installing a separate MCP server for each app, you connect your apps once (GitHub, Gmail, Slack, Notion, Meta Ads + 800 more) through one OAuth login, then paste a single URL into Claude or Cursor. Every connected app becomes available as tools automatically — no per-app install, no API keys to juggle. It is bundled into the StackPicks ₹99 / $2.99 lifetime plan, making it the cheapest Composio alternative for solo builders.

The problem: one MCP server per app doesn't scale

The Model Context Protocol (MCP) is brilliant — it lets Claude, Cursor, and other AI agents call real tools instead of guessing. But the default setup has a painful shape: one MCP server per app.

Want Claude to read your GitHub? Install the GitHub MCP server, generate a personal access token, edit your config, restart Claude. Want Slack too? Repeat. Notion? Repeat. Gmail? Repeat. Within a week your claude_desktop_config.json is a wall of JSON and a graveyard of API keys.

This is the same problem Zapier solved for automation and Plaid solved for banking: nobody wants to integrate N services N times. They want one connection that fans out.

The fix: a unified MCP gateway

A unified MCP gateway flips the model. You connect your apps once — through a web dashboard, with normal OAuth ("Allow StackPicks to access your GitHub?") — and the gateway exposes all of them to your AI agent through a single connection.

That's what we built with StackPicks Connect. The shape:

  1. Connect apps once on the web — one-click OAuth per app, no API keys
  2. Paste one URL into Claude: https://stackpicks.dev/api/mcp
  3. Every connected app becomes toolsgithub_create_pr, gmail_send_email, slack_post_message, and so on
  4. Add an app later → it shows up in Claude automatically, no config edit, no restart

The OAuth tokens live in an encrypted vault, never on your machine and never in your AI client's config. Your AI agent only ever holds a short-lived access token scoped to you.

How it actually works

Claude  ──►  StackPicks MCP gateway  ──►  GitHub / Gmail / Slack / …
   (one connection)        (holds your OAuth tokens, fans out per request)

When Claude calls a tool like github_list_repos, the gateway looks up your stored GitHub connection, fetches a fresh token, calls GitHub's API, and returns the result. You never see the token. The same gateway handles every app you've connected.

This is the architecture behind Composio, Pipedream Connect, and now StackPicks Connect. The difference is who it's built for.

If you're an enterprise wiring agents into a product, Composio's depth is worth it. If you're a solo builder or small team who just wants Claude to *use your apps* without a billing meter, StackPicks Connect is the cheaper, simpler path — it's bundled into the one-time lifetime plan, no per-call cost.

When you still want individual MCP servers

A gateway can't do everything. **Local MCP servers** — filesystem access, a Postgres running on localhost, a Memory graph — have to run on your machine. A hosted gateway can't reach `localhost`. For those, install the individual server directly. We keep a curated directory of 90+ MCP servers for exactly that.

Rule of thumb:

  • SaaS apps (GitHub, Slack, Gmail, Stripe…) → use the gateway
  • Local/system resources (your disk, a local DB) → install the individual MCP server

Connecting Claude in under two minutes

  1. Sign up at stackpicks.dev and connect an app (start with GitHub)
  2. In Claude → Settings → Connectors → Add custom connector
  3. Paste: https://stackpicks.dev/api/mcp
  4. Claude opens a browser → log into StackPicks → approve
  5. Ask Claude: *"List my GitHub repos"* — it works

No npx, no JSON, no API key. Works on Claude web, desktop, and mobile. (Prefer the old way? There's also an npx package and an API-key URL for clients without OAuth support.)

The advertising angle (for marketers)

One underrated use: ad-ops through Claude. Connect Meta Ads, Google Ads, and Google Analytics, then ask:

> *"Pull last week's Meta Ads spend and ROAS by campaign, and flag anything under 1.5x."*

Claude calls the ad-platform tools, pulls the numbers, and gives you the analysis — no exporting CSVs, no switching dashboards. For affiliate marketers and growth folks this is the killer workflow.

Bottom line

The "one MCP server per app" era is ending the same way "one API integration per service" ended. A unified gateway is simply less work. StackPicks Connect makes it consumer-grade — one URL, browser login, 800+ apps, ₹99/$2.99 lifetime — and pairs it with our curated directory of open-source tools and MCP servers for the local stuff a gateway can't reach.

Connect your first app and give Claude real-world hands. → Open StackPicks Connect

Frequently asked questions

What is a unified MCP gateway?+

A unified MCP gateway is a single Model Context Protocol server that exposes tools from many different apps at once. Instead of installing the GitHub MCP, the Slack MCP, the Notion MCP separately — each with its own config and API key — you connect those apps once through the gateway and it presents all their tools to your AI agent through one connection. StackPicks Connect, Composio, and Pipedream Connect are examples.

How is StackPicks Connect different from installing individual MCP servers?+

Individual MCP servers each need their own config block, their own API keys or OAuth setup, and a client restart when you add one. StackPicks Connect needs one setup: you OAuth your apps on the web dashboard, paste one URL into Claude, and every connected app shows up as tools. Add a new app later and it appears in Claude automatically — no config edit, no restart.

Is StackPicks Connect a Composio alternative?+

Yes. Both are unified MCP/tool gateways that let AI agents act across hundreds of apps via OAuth. The difference: Composio targets developers and prices per usage; StackPicks Connect is consumer-grade (paste one URL, log in via browser) and is bundled into a one-time ₹99 / $2.99 lifetime plan with no per-call billing — aimed at solo builders and small teams.

How do I connect my apps to Claude with StackPicks?+

Three steps: (1) Sign up at stackpicks.dev and connect your apps (GitHub, Gmail, Slack…) via one-click OAuth. (2) In Claude → Settings → Connectors → Add custom connector, paste https://stackpicks.dev/api/mcp. (3) Claude opens a browser to log into StackPicks, you approve, done. Every connected app is now usable in Claude. Works on Claude web, desktop, and mobile.

Which apps can I connect?+

The catalog has 800+ apps across dev tools, email, messaging, CRM, payments, advertising, analytics and more. Live providers roll out continuously — GitHub, Slack, Notion, Gmail, Google Drive, Linear, Stripe, plus advertising platforms like Meta Ads, Google Ads, and TikTok Ads. Apps not yet wired show a "notify me" option that signals demand.

Do I need to copy an API key?+

No. StackPicks Connect implements full OAuth 2.1 — you paste one generic URL (https://stackpicks.dev/api/mcp) into Claude, and Claude runs a browser login flow to authenticate you. No API key to copy, no token to manage. There is also an optional API-key URL and an npx package for clients that prefer those.
