Development MCP Servers

Integrate user-authorized source-account verification into products. Find, build, test, and maintain verification providers using the Reclaim Builder MCP.

Live, read-only blockchain data across 60+ EVM chains: wallets, tokens, transactions, contracts and gas. Official Etherscan MCP server.

Publish HTML5, Unity WebGL and Godot web games to the Gamealia portal from your AI assistant: integrate the SDK, run the portal automatic test locally, upload, translate the listing and submit for review. 60-70% ad revenue share, no exclusivity.

Hosted MCP server for regression testing. Your agent saves browser and API flows for a web app, runs them in cloud Chromium and reads failures with screenshots. OAuth or token. Free plan: 20 runs a month.

AI code review for GitHub pull requests. Connect any MCP client to IonWarp with one server URL and a personal access token.

Turn a public GitHub pull request into a cited handoff: decision, evidence, unknowns, owner and next check. No sign-in, read-only.

Verification layer for AI coding agents: every change proves itself before it lands.

Stealth browser MCP with three engines, diff observations, site memory, and a human CAPTCHA handoff.

A local MCP server that connects AI assistants to a live Roblox executor session.

Read-only reference for the Kepler OGame bot's .ank scripting API: search functions, exact signatures, return values and examples, so an AI assistant writes working Kepler scripts.

Cuelark Tools is a free remote MCP server with 11 exact, deterministic tools for AI assistants: format, validate and convert JSON (YAML, CSV), count OpenAI tokens (o200k/cl100k), explain cron expressions with next runs in any time zone, calculate dates, working days and age (with UPSC and SSC age cut-offs from the official notices), count words, characters and X/SMS lengths, convert CGPA with official CBSE, VTU and Anna University formulas, convert time zones with daylight saving, work out print sizes in pixels at any DPI, and look up Cuelark UI shadcn components with their install command. No sign-up. Inputs are not logged or stored, and there are no image or PDF tools on purpose: those run only in the browser at tools.cuelark.com so files never leave your device.

IndieBob writes each cold email for one prospect after reading their website: a subject, an opening about their business and a bridge to your offer, in their language. You approve the first email to everyone. Cookieless analytics then show which posts and links bring signups.

Safely run the code your agents write. Submilli runs each agent program in its own WebAssembly sandbox and checks every call against rules you set, outside the model. It consumes MCP servers as Packages and exposes an MCP endpoint per Blueprint. Apache-2.0, self-hosted or hosted.

Static security scanner and MCP guard for AI-generated codebases, with 85+ rules covering leaked client secrets, unauthenticated API routes, Supabase RLS, prompt injection sinks, and SKILL.md/MCP poisoning.

Cut AI coding agent token usage by up to 90% with AST file slicing, 1-hop dependency graphs, diff/command sanitization, scoped search, and pre-flight security guards.

Autonomous headless Playwright QA server with an 8-trap browser inspection engine covering console errors, network failures, layout collisions, 44px touch targets, WCAG accessibility, Core Web Vitals performance, and dark/light parity.

Records how a CLI tool behaves (stdout, stderr, exit codes) into golden tests, then replays them against another implementation, e.g. a Rust or Go rewrite. Works as a CLI and an MCP server.

Browser control and recording context for AI coding agents. Record or upload UI feedback, then share a replayable link or structured Markdown/JSON context with Claude Code or Codex.

Manage your own Linux servers from ChatGPT and MCP-compatible AI clients via a hosted OAuth-protected MCP endpoint: persistent shell sessions, health metrics, systemd, Docker and file operations. Requires installing an outbound Linux agent with explicitly approved root access.

The Magic Lane MCP Docs Server enables any AI agent or application to become a Magic Lane documentation expert. Through the Model Context Protocol, your AI assistant gains instant, searchable access to the live Magic Lane developer documentation: the developer guides (account setup, API keys, Map Studio, the Magic Lane MCP Server), the full references of the Maps SDKs for Flutter, Android, iOS, C++, and TypeScript (maps & 3D scene, markers, places & search, routing & navigation, positioning, offline maps, weather, fleet management, migration guides), and the Cloud REST APIs (Routing, Isochrones, Search, Reverse Geocoding, Fleet Management, Geofences, Vector Tiles, Offline Maps).

Remote MCP server for Google Play Console: releases, ratings, reviews and stability of your Android apps. Sign in with Google.

Gives coding agents a local decision graph built from your repo's git history, PRs, ADRs and CLAUDE.md/AGENTS.md, plus Jira, Linear, Notion, Slack and others read-only. Agents ask it what was decided and why, and every edit is checked against it before it's written.

Vendor-agnostic governance and traceability layer for AI coding agents: records decisions, tracks tasks, and anchors code back to its rationale via an MCP server and CLI.

30 herramientas gratis que auditan servidores MCP y el código de tu agente de IA en busca de riesgos conocidos: inyección SQL/comandos, SSRF, secretos expuestos, descripciones envenenadas, suplantación de llamadas a herramienta ("Repeat-After-Me"), y más — antes de que el agente ejecute algo irreversible. Incluye Vigía, un agente que elige solo qué herramientas usar y responde en español.

Remote MCP server for App Store Connect: review status, versions, builds and ratings of your iOS and Mac apps, asked in plain language.

Bigshot's built-in MCP server lets coding agents search your Mac screenshots by text, description or similar image, and look up the source code behind them. Runs on your Mac with the Bigshot app.

Remote hardware-in-the-loop benches: AI agents flash an ELF/BIN on real STM32 and LPC boards and read back UART and pass/fail in seconds.

Debug VCD, FST and GHW waveforms: decode AXI, SPI and UART, search cycles, show evidence in the user's viewer.

Remote MCP server for PageSpeed Insights: Lighthouse scores, Core Web Vitals and what to fix on any page, asked in plain language.

Lets AI agents build, run and test Godot 4 projects in the real editor. Free Lite tier.
