"Interacting with a webpage using a browser plugin and live browser instance" matching MCP servers:

A validation layer for AI coding assistants that enforces explicit LLM evaluations on plans, code diffs, and tests to ensure safer and higher-quality code.

Gives AI coding tools access to the CSS cascade the way DevTools does — which rules matched, which won, where each came from.

Codebase Q&A agent with git-history awareness. Explore a repo with list_files, read_file, and search, plus git log, blame, and diff and a repo map to answer "why did this change?" questions. Runs locally as an MCP server for Claude Code and other MCP clients.

Enables scaffolding, validating, and managing plugins for the Motor Agéntico ecosystem, with tools to generate plugin structures and verify compliance with the plugin standard.

Provides Pine Script v6 validation and reference lookup for coding agents, enabling them to write correct TradingView indicators with real-time diagnostics and function signatures.

An MCP server that exposes the local Grok CLI to Codex for bounded repo work, reviews, rescue analysis, adversarial checks, session listing/export, and background job management while keeping Codex hidden context out of scope.

A lean, local knowledge graph that joins a repo's code to its aSPARK delivery artifacts, enabling agents to trace user stories to code and assess impact of changes, served over MCP.

Enables executing arbitrary Joern/CPGQL queries against a loaded Code Property Graph, loading source code in multiple languages (PHP, Java, JavaScript, Python, C/C++) to build new CPGs, and inspecting loaded projects and the active workspace. It communicates with a running Joern server over its synchronous HTTP query endpoint, so no state polling is required.

QECTOR Quantum Error Correction: High-performance, mathematically verified local QEC engineering environment for Claude Code and Claude Desktop.

Provides audit_plugin_health and prepare_semantic_review tools for deterministic inspection of Codex plugins and Agent Skills, generating evidence-backed reports without executing or transmitting target code.

Zero-dependency MCP server inspector for protocol conformance, tool annotations, and capability checks.

Enables AI agents and MCP clients to compute real-time, in-memory unified diffs between versions of live artifacts along with structured change telemetry. It runs as a deterministic, zero-dependency Python MCP server that plugs into Claude Desktop, Cursor, or Windsurf for diff and change-tracking workflows.

locidx

Enables searching, downloading, extracting, and comparing WordPress.org plugins with local plugins via natural language.

This MCP server assists Minecraft Java plugin developers by providing dependency documentation lookups, version checking, and automated scanning for Gradle and Maven projects. It supports popular APIs such as Paper, Spigot, and LuckPerms to streamline plugin development and workspace analysis.

A self-contained Claude Code plugin that profiles a project by running a fixed DAG to emit agent-facing context pages, a human/developer guide, and a queryable vectorstore.

MCP server that helps AI models understand Vite/Nuxt applications better, available as both a Nuxt module and Vite plugin.

A medical MCP server for agents that diagnoses tracebacks, provides exact fixes, and converts verified solutions into reusable prescriptions, plus a guard for destructive shell commands.

Connects to Xcode's build system to extract, parse, and display errors and warnings from your Swift projects, helping AI assistants quickly identify code issues without manually searching through build logs.

A server that exposes the Jadx decompiler API over HTTP, enabling Claude to interact with decompiled Java/Android code to list classes, fetch source code, inspect methods/fields, and extract code live.
