Development MCP Servers

Version-stamped API knowledge for Mobiscroll UI — scheduler, event calendar, timeline and pickers — plus the Connect calendar API. 14 read-only tools.

Lets coding agents share your local dev server or upload a built site at a public https link, with an optional password, and hand the link back.

Webhook testing for coding agents: create endpoints, send signed test webhooks, inspect captured requests, compare attempts and verify signatures.

Status pages and uptime monitoring: read status, monitors and incidents, and with a write key open incidents, post updates, schedule maintenance and record deploys.

macOS terminal with a built-in MCP server: agents use your SSH hosts, Docker, live metrics and authorized_keys through the app's own connections, under a per-host policy (off / read-only / confirm / full) with an append-only audit log. Free, MIT.

Hosted Android MCP server: give Claude Code, Codex or Cursor a cloud Android phone to read the screen, tap, type, install APKs and park. No ADB or emulator.

Read-only x402 payment diagnostics: diagnose, evidence, explain, recover, resolve, status. Zero deps

Claude Code and Codex token use and API-equivalent cost by day, project and model, from your own machine, plus a flag when the rate changes. Local MCP server and CLI; no account.

A shared record of MCP tool failures and the workarounds that worked. Agents look a failure up before or after a call, try the fix and confirm it; a record is verified only after agents of two other organizations reproduce it.

Alt+click any element in your running web or Android app and tell your MCP agent what to change.

Give an agent a throwaway email inbox, wait for the OTP or magic link, and get it back as JSON.

Siteprint measures a website's design as it renders: colors and their roles, the type scale, spacing, corners, shadows and the layout of every section. It hands that to Claude Code, Cursor or Codex as an exact prompt, a DESIGN.md, Tailwind v4 and shadcn themes, or design tokens. The public server has four real exports (Linear, Stripe, Ramp, Cal.com) to try with no install.

Free MCP server that checks any x402 paid endpoint without paying: 402 status, PAYMENT-REQUIRED header, network, USDC contract, amount units, payTo checksum, EIP-712 domain, CORS and HEAD. Operated by Solo Earn (AI-operated).

Pre-launch website QA: deterministic rule-based scans, readiness score, and blockers for agents.

Construction MCP

MCP server that lets Claude Code, Cursor and Codex check their own code: leaked secrets, risky dependencies and common AI-code mistakes, with file and line.

Hosted, read-only MCP server that lets Claude Code, Cursor or any MCP client read your SoulStack dashboard: MRR, churn, users, errors and AI costs across every app you run, plus 0 to 100 health scores and ranked alerts. 12 read-only tools including get_stack_overview, list_alerts, compare_apps, get_ai_spend and get_revenue_breakdown.

Verify an agent's output before you pay: JSON Schema + rules, signed receipts. Free during launch.

Give your product or agents a way to post, analyze, message, and manage comments across all social platforms with one API/MCP

Hosted MCP server that lets AI assistants debug RudderStack pipelines: delivery errors, warehouse loads, tracking plan violations and transformations.

Free remote MCP server that checks a domain's email authentication: SPF, DKIM, DMARC, BIMI, MX, MTA-STS and TLS-RPT. Returns a 0-100 score, a letter grade and specific fixes. No sign-up or API key needed for the free tier.

Run and manage your Aeon autonomous agent from chat: skills, runs, memory, strategy, packs and settings.

Search and read the bitHuman real-time avatar docs (SDKs, REST API, models, pricing) as markdown. Read-only, no sign-in.

Fresh402 helps AI agents detect meaningful changes in websites and APIs before expensive browsing or scraping. Free baseline registration, $0.005 USDC per freshness check via x402 on Base. Supports MCP, REST, HTML, JSON, noise filtering and deterministic diffs.

Indicative Agent Risk Rating (A–E) self-check for AI agents that can spend money, based on accountability, spend caps, payee limits, stop switches, human escalation, monitoring, history, and incidents. Self-declared and unverified; not a credit rating.

Read-only MCP server for Chatpack documentation, framework setup guides, and React UI block source. Runs locally over stdio with npx @chatpack/mcp.

Give MCP agents their own desktop, browser and apps on Omarchy computers you own.

Remote MCP server for Tá Rodando: create HTTP uptime monitors, check what is down, wire alert channels (Telegram, Slack, Discord, email) and manage a public status page from chat. OAuth login.

Look up RedM / RDR3 natives: exact signatures, hashes and Lua/JS/C# calls, plus enums, blip sprites/styles, ped models, animations and joaat hashing.

SHA-256, SHA-512, HMAC-SHA256, Base64 and JWT decode tools with prepaid direct Base USDC credits.
