Development MCP Servers

Ask your agent for an app and Homespun deploys it: its own URL, magic-link sign in, a shared database, per-role permissions and file uploads.

Keyless MCP server giving AI agents CVE lookups (NVD), package-vulnerability checks (OSV) and dependency-manifest audits. No API key; free tier.

A tiny MCP server that lets you praise your AI by typing ㅊㅊ (or cc). K-drama & Hollywood style compliments, 36 lines, ko/en. A Korean developer's experiment in AI kindness — built with an ensemble of AIs. Install: npx -y heungbu26-mcp

Keyless MCP server giving AI agents npm/PyPI/crates.io package intel: metadata, versions, popularity, dependencies, health and advisories. Free tier.

Drive iOS simulators from Claude Code, Cursor or Codex by accessibility label instead of screenshot-and-tap-coordinates, with leases and a warm pool so multiple agents can share one Mac.

The Mac window manager your agent can drive. Snap zones, saved workspaces, keep-awake, screenshots and on-device OCR — 19 MCP tools bridging to a loopback API on your own machine. No account, no cloud, no telemetry.

Narrow code retrieval for coding agents — outlines, symbol bodies, dependency graphs, and persistent memory instead of whole-file reads.

AI that builds and runs your business — 24/7

Shows what a checkout you did not write tells your agent to do before you run it — instruction files and their imports, hook commands wired to agent events, MCP servers the repo declares, and the skills and subagents it ships.

Shows what your coding agent can do without asking you: every settings file that contributes permission rules, which one wins, what runs unattended, and the rules the client accepts and then ignores.

Unofficial MCP server that manages Healthchecks.io checks via its Management API.

Thirteen live MCP tools for x402 and MPP data, web extraction, agent discoverability, security audits, Morpho decisions, and work preflight.

Keyless MCP server giving AI agents domain recon: RDAP registration, DNS, email deliverability, tech-stack fingerprint and subdomain discovery. Free tier.

AI code reviews for GitHub, GitLab, Azure DevOps & Bitbucket PR/MR URLs from Cursor, Claude, or Copilot.

Native macOS SSH client with 26 local MCP tools for visible terminals, SFTP, SSH keys, connections, and read-only observability.

Control Unreal Engine with AI. An MCP server that gives AI assistants (like Claude and Cursor) direct, programmatic access to the Unreal Engine environment to manipulate scenes, spawn objects, and execute commands.

MCP client/host: a Mac, iPhone and web workbench that runs Claude Code, Codex, Cursor and Grok sessions and manages their MCP server configs.

Ground-truth code graph context for your own private codebase — exact callers, callees, symbol definitions, and dependencies.

Compact, cached, loop-aware lint/type diagnostics for JS/TS coding agents. Wraps Oxlint, tsc, and Biome.

Self-hosted MCP and AI gateway that turns rough natural language into structured prompts with governed routing and reproducible verification for Codex, Cursor, and Cline.

Gives AI agents public URLs (tunnels) for localhost, live HTTP traffic inspection, snapshot publishing, and access control.

Convert technical-drawing PDFs between metric and imperial — dimensions, tolerances, ISO fits, M⇄UNC threads and surface roughness — with every value stamped in place on the PDF.

Review & approve AI agent task plans in a ComfyUI-style node editor, right in your terminal (MCP server + TUI)

Qencode lets AI assistants transcode, analyze, edit, optimize, and deliver video using natural language, powered by a cloud video processing platform.

Fences side-effecting tool calls so racing agents and retries produce exactly one execution, replaying a sealed receipt to the duplicates.

Gives coding agents deterministic, read-only documentation handoffs with edit boundaries, ownership, and required checks before repository changes.

Validates AI-generated Python: syntax, lint, security scan and deterministic repair.

Model Context Protocol server for Vynix. It gives coding agents direct access to visual feedback, bug reports, screenshots, diagnostics, comments, and issue workflows so agents can reason from real context instead of guessing.

An MCP server for App Store Connect: 41 tools to ship a release from your agent, covering metadata, screenshots, builds, TestFlight, in-app purchases, submit and release.

Generate and edit cloud architecture diagrams as native draw.io files, from a prompt or from Terraform
