Development MCP Servers

Rules and code for marking AI images, video and audio with C2PA and watermarks, per market and per stack. Keyless remote server.

Cookieless web analytics that shows who visits

A gate between an AI agent and its tools. The agent proposes, you see a preview and approve or decline, then it reads back what happened and writes a tamper-evident log.

Your coding agent ships; checkmyapp walks your live app like a first-time user after every deploy and reports what broke, with screenshots.

Tells AI coding agents what changed in the APIs and SDKs they use: breaking changes, deprecations and security fixes for 38 popular libraries (OpenAI, Anthropic, Stripe, Next.js, React, Node and more) since the version their code targets. Free tools list sources and headlines; upgrade checks are paid per call via x402 (USDC on Base).

Manage your CookiePal cookie banner from Claude: domains, the banner tag and style, and cookie scan reports.

The instant free CDN and static file host. Host and serve CSS, JavaScript, JSON, XML, TXT, Markdown, and images worldwide with zero configuration, full CORS headers, and direct raw CDN links.

Timezone and business-day truth for AI agents: current time in any IANA zone, DST-safe conversions, business-day math with holidays. Remote MCP server (Streamable HTTP) plus REST API. Free 200 calls/day.

Check a list of links and see which work, redirect, or are broken.

Receive-only temporary inboxes for authorized QA. Create inboxes and read messages, verification codes and links with inbox-specific tokens.

Hosted MCP server for UberLLM, one OpenAI- and Anthropic-compatible API key for 490+ AI models. Tools: list and price models, make and edit images, start videos and wait for the job, read your balance. Auth: your UberLLM API key as a Bearer token; a tool call is billed like the same API request and failed requests are not billed.

Plan a software project and check how fast a website is: feature estimates, team, timeline and budget, or a PageSpeed audit of any public page.

Deterministic secret, PII and PHI checks for your CLI, git hooks, CI and MCP, with editable scaffolds for NIST SSDF, ISO 27001 and India's DPDP Act.

Drive your open Unreal Engine 5.7 or 5.8 editor from your agent: 328 editor tools for actors, Blueprints, materials, input, widgets and play-in-editor.

Reports OpenAI Codex token use, API-equivalent cost and the ChatGPT plan's 5-hour and weekly limits from Codex's local session logs.

Use AirBuild from your own AI assistant. Talk to your AirBuild agents, follow your projects and run your team from Claude, ChatGPT, Cursor, Codex or any MCP client. Remote MCP server with OAuth sign-in, nothing to install.

Remote MCP server for Sitegoalie, a hosted dashboard for agencies that look after client WordPress sites. Read site status (pending updates, issues, uptime, PHP errors, broken links, performance, client reports) and, when the workspace allows changes, run a Safe Update, send a client report or log work.

Connect, call and coordinate AI agents, hosted or self-hosted. HTTP, MCP, A2A and Go/TS/Python SDKs; Apache-2.0 Core with traceable runs.

Siri Skills helps iOS developers build Siri app skills: the SKILL.md files that live in an app's Skills.skillsbundle and teach Siri how to combine the app's App Intents. The MCP server can validate a SKILL.md against Apple's rules (frontmatter, naming, description limits), list and fetch 40 ready-made example skills across app categories, scaffold new skills, and read the companion guides. Use it locally over stdio with npx, or connect to the free hosted endpoint — no API key. Works with Claude, Cursor, VS Code and other MCP clients. Open source under MIT.

Order human-run real-device app tests from your coding agent; verified bugs come back as ready-to-paste fix prompts. Real testers on real phones, laptops and browsers, fixed price, report in 3 days.

Dated, sourced AI facts from Kingy AI: API prices, plans, usage limits, retirements and shutdowns.

The ReUI MCP server connects your coding agent to the live ReUI registry.

Free desktop process manager (macOS, Windows, Linux) with an MCP server: agents start, stop and read logs of your local dev servers and databases.

Read-only relay pricing, uptime, latency, availability, and model-level purity data for AI agents.

Hand a critiqued system design to your coding agent: brief, build order and drift check. Needs a SkeletIQ API token

Read-only facts about servers in the official MCP registry: nine record checks per server, topics, registry size and daily changes. No key.

Test healthcare AI agents' medication claims against cited FDA label text. Deterministic rules, not a model, decide every verdict. Synthetic data only. Not for clinical use.

Get calibrated yes or no answers, choices and scores from TypeSafe's Jev, for one item or 1000 rows.

Remote MCP server for the UplinkSwitch model API: list_models and list_media_models with live per-token prices, estimate a request's cost, read the daily model-identity check (proof), and chat on any of 470+ models with a prepaid key. Streamable HTTP, stateless; list, estimate and proof need no key.

Submit AI coding agent work to the hosted control plane and retrieve run status and artifact references.
