Best MCP Servers for Next.js + Supabase Projects in 2026

Next.js + Supabase + Vercel + Stripe is the modern indie stack, and it moves fast. The problem is that moving fast means constantly switching between your editor, the Supabase dashboard, the Vercel console, Stripe's test mode, and documentation tabs. MCP servers eliminate most of that context switching by giving your AI assistant live access to your actual infrastructure. For a detailed comparison of Supabase vs Firebase backends, see Supabase MCP vs Firebase MCP.

Supabase MCP -- Your Database in the Conversation

Author: Supabase | Tools: 25 | Requires: Supabase access token

Twenty-five tools covering the full Supabase platform: listing tables, running SQL, applying migrations, managing branches, deploying edge functions, checking logs, and running security and performance advisors. The assistant sees your actual tables, RLS policies, and migrations -- not a generic idea of Supabase. For a detailed guide, see how to use Supabase MCP.

Why use it

• Set up Row Level Security policies by describing the access pattern you want -- the assistant reads your schema and applies the correct migration
• Debug slow queries by running them against your actual database and checking the query plan
• Inspect your real table structure before writing code, so it references columns that actually exist
• Run security advisors to catch missing RLS policies after schema changes

Configuration

{
  "mcpServers": {
    "supabase": {
      "command": "npx",
      "args": ["-y", "@supabase/mcp-server-supabase"],
      "env": {
        "SUPABASE_ACCESS_TOKEN": "your-access-token"
      }
    }
  }
}

Generate your access token from the Supabase dashboard under Account Settings.

Vercel MCP -- Deployment Without the Dashboard

Author: Vercel | Tools: 12 | Requires: Vercel API token

Twelve tools for interacting with Vercel projects: listing deployments and statuses, inspecting build logs, managing environment variables across preview and production, configuring domains, and triggering redeployments.

Why use it

• Check deployment status and read build logs without opening vercel.com
• Update environment variables across environments and trigger a redeployment in one step
• Inspect build errors when deploys fail after a PR merge
• Manage domain configuration from your editor

Configuration

{
  "mcpServers": {
    "vercel": {
      "command": "npx",
      "args": ["-y", "vercel-mcp"],
      "env": {
        "VERCEL_API_TOKEN": "your-api-token"
      }
    }
  }
}

Create your token from the Vercel dashboard under Account Settings > Tokens.

Context7 MCP -- Next.js and Supabase Docs That Are Actually Current

Author: Upstash | Tools: 2 | Setup: Zero-config (npx)

Two tools for fetching live documentation. Next.js 15 changed caching defaults. Supabase updated their client library from @supabase/auth-helpers-nextjs to @supabase/ssr. Your assistant's training data is always at least a few months behind.

Why use it

• Get correct Next.js 15 server actions patterns instead of the Next.js 14 revalidatePath approach
• Use the current @supabase/ssr package API instead of the deprecated @supabase/auth-helpers-nextjs
• Get working code examples for any npm package in your stack
• Avoid debugging code that "looks right" but uses deprecated function signatures

Configuration

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@upstash/context7-mcp"]
    }
  }
}

No API key required.

Magic MCP (21st.dev) -- UI Components for the App Router

Author: 21st.dev | Tools: 4 | Requires: 21st.dev API key

Four tools: component builder, component search, component refiner, and logo search. Generates React + Tailwind components that work with both client and server components. When you need a dashboard layout, settings page, pricing table, or user profile card, Magic MCP gets you a production-ready starting point in seconds.

Why use it

• Generate a responsive pricing page with tier comparison, monthly/annual toggle, and CTA buttons, then wire up Stripe checkout links
• Refine a rough data table for Supabase query results -- fix spacing, add hover states, improve loading indicators
• Search 21st.dev's library for existing components before building from scratch
• Get components that follow React + Tailwind conventions matching your Next.js project

Configuration

{
  "mcpServers": {
    "magic": {
      "command": "npx",
      "args": ["-y", "@21st-dev/magic"],
      "env": {
        "TWENTY_FIRST_API_KEY": "your-api-key"
      }
    }
  }
}

Get your API key from 21st.dev.

Stripe MCP -- Payments Without Leaving Your Editor

Author: Stripe | Tools: 15 | Requires: Stripe secret key

Fifteen tools covering core Stripe operations: products, prices, customers, subscriptions, invoices, and payment links. This is the official Stripe agent toolkit. The assistant can query your test mode data, create products and price tiers, and inspect webhook events. For a detailed guide, see how to use Stripe MCP.

Why use it

• Create products with price tiers in Stripe, then write the checkout API route and webhook handler with real product IDs (not placeholders)
• Debug webhook failures by querying a customer's recent events and tracing the issue
• Set up a subscription flow end-to-end: Stripe products, checkout session, webhook handler that updates Supabase
• Inspect your current Stripe setup to understand existing products and prices

Configuration

{
  "mcpServers": {
    "stripe": {
      "command": "npx",
      "args": ["-y", "@stripe/mcp", "--tools=all"],
      "env": {
        "STRIPE_SECRET_KEY": "sk_test_your-test-key"
      }
    }
  }
}

Use your test mode secret key during development. Never use the live key in your editor.
