"Next.js" matching MCP servers:

Analyze React render performance in Next.js apps. Detects rerender storms, commit spikes, and slow components.

MCP Server for Next.js build & bundle analysis. Chunk size, shared chunk attribution, and code-split suggestions for MCP clients

Open-source Next.js + Supabase CMS with a per-site MCP server for building and editing sites from any agent

Gives AI coding assistants live access to the Hyperiux Vault catalog of React and Next.js animation effects. Search effects, inspect dependencies and installation instructions, and retrieve source for free effects.

Explains known developer errors offline and deterministically (CORS, ESM/CommonJS, npm ERESOLVE, Next.js builds, Postgres connection and DATABASE_URL errors). One tool, explain_error; no LLM, no network.

Turns an existing Express, Hono, Fastify, or Next.js API into a Streamable HTTP MCP endpoint, exposing one tool per OpenAPI operation that runs in-process through the app's existing routes, auth, validation, and handlers. It also serves discovery documents and readiness guidance so models can better understand and call the API.

Analyze V8/Chrome CPU profiles in Next.js & Node.js apps. Hotspots, package cost attribution, and optimization suggestions for MCP clients like Claude Code and GitHub Copilot

Static security scanner for AI-generated (vibe-coded) Supabase and Next.js apps. Runs as an MCP server so an LLM can scan, explain findings, and produce fixes while it writes code, all locally and offline.

Self-hostable MCP server for portable AI agent playbooks: manage skills, MCP configurations, personas, instructions, memory, and canvas documents. The public Next.js source implements Streamable HTTP MCP at /api/mcp/manage; users can run it with the repository's Dockerfile and their own database configuration.

Enables AI coding agents to observe real-time Node, Vite, Next.js, Storybook, TypeScript, and browser runtime errors from a wrapped dev server, source-mapped to exact file, line, and column with the log lines preceding each crash. It exposes MCP tools for listing open errors, fetching full stack details, and checking or marking fixes as resolved, all locally with no code changes.

Enables coding agents to capture a live website's rendered frontend, export it as an editable Next.js or Astro project, and re-verify the result pixel by pixel to confirm visual fidelity held.

Persistent daemon that compresses codebases via AST body folding before indexing them for AI coding assistants like Claude Code and Cursor 57-89% token reduction with sub-millisecond queries, verified on Django, Spring, and Next.js.

MCP tools for coding agents to create, start, pause and finish A/B tests, push TypeScript experiment config, and read results for React and Next.js apps. SplitHub Cloud returns statistical verdicts; self-hosted projects return raw visitor and conversion counts.

Sub-1ms cross-stack AST contract layer and compiler verification engine mapping React/Next.js routes to FastAPI and SQLAlchemy models for AI coding agents.

Enables coding agents to render React, browser-renderable Next.js, and Vue components from source, then inspect cropped screenshots and structured visual/accessibility evidence without starting the application.

Enables AI coding assistants to run static analysis on GitHub repositories, raw code snippets, or local directories to detect cloud cost leaks in Terraform/AWS configs, PostgreSQL migration table-lock hazards, and OWASP/Next.js API security gaps. Each finding returns structured severity, line-level detail, and drop-in fixes.

Enables coding agents to load frontend anti-slop rules and deterministically verify generated React, Next.js, and Tailwind UI before completion. It audits for common AI-generated patterns, checks stylesheet/token wiring, provides real or placeholder images, and verifies TypeScript compilation.

ost-agnostic MCP + OAuth ports — you bring the runtime and IdP; the library owns the connector protocol. Web-standard Request → Response. Same handler on Cloudflare Workers, Next.js App Router, Deno, Bun, and Node HTTP via mcp-trellis/node. Zero runtime dependencies.

A Node.js MCP server that loads plugins, registers tools via the MCP SDK, and exposes functionality over stdio with built-in persistence and a Next.js web UI. It provides a management stack for MCP tools with plugin lifecycle management and security controls.
