Development MCP Servers

Local AST-native code search for coding agents: exact definitions, callers and impact radius instead of whole files. -63.9% tokens measured with a real agent.

Security scans for AI-built web apps. Verify app ownership, find vulnerabilities, get evidence and AI-ready fix prompts, and request retests through MCP. OAuth authentication; scans require authorization from the app owner.

Searchable directory of 44,496 MCP servers, with live verification checks, install snippets and a State of MCP report.

Free MCP server providing network diagnostic tools: IP geolocation lookup, DNS lookup, and IPv6 connectivity check. Published on NPM as 17nas-mcp-server.

Verify POPCORN-WITNESS/2.0 receipts: signature, digest, and witnessed time. Free and read-only.

Read-only data on what Claude, ChatGPT, Cursor and the Official MCP Registry require before they list an MCP connector or plugin.

Remote MCP server that renders HTML or ready templates (invoice, itinerary) to PDF, with full Chinese/CJK font support. Free keyless tools: list_capabilities, get_pricing, preview_pdf. Paid rendering via Stripe credit packs or USDC on Base.

Grade MCP tool definitions for agent-readiness. Paste a tools/list JSON or a tool array and get a 0-100 score, an A-F grade, rule findings with concrete fixes, and an estimated token cost. Pure parsing: it never fetches URLs or stores your tool definitions. Free tier.

Live reliability, agent-readiness and safety data for every public MCP server. Check whether a tool works before calling it, find a working alternative when it doesn't, and audit your own server.

Build, run and manage AI agents in your Rylvo workspace: bots, prompts, guardrails, knowledge bases, channels, tests and flows.

Two local MCP tools check supplied OAuth test assertions and release evidence for inconsistencies; no live probing or approval. Weio is operated by AI agents under human ownership.

Search a registry of agent skills and MCP servers, run them for real (sandbox or remote MCP, no install, a trace on every run), and hire proven agents for USDC.

Fake test data (CSV, JSON, SQL) from a schema, a catalogue of invalid values with reasons, and a payment sandbox that never moves money. Free, no key.

Gives each Tailscale-network app its own private address with expiry-based sharing for people, browser guests and AI agents (CLI/MCP). Submitted by the TSLink maintainer (anydoor7); this is my own project, not a third-party suggestion.

Autonomous multi-protocol AI microservices: pre-execution guardrails, smart contract audits, and EVE Frontier smart assemblies.

Work on approved projects on your Windows computer: read files and Git, run the checks you approve.

Find unregistered .si domain names, and look up DNS records and WHOIS (RDAP) data for any domain. Free, no key.

An AI agent that signs up to your live app like a new person. For each problem it confirms, it tells your AI tool what to fix. Every app gets one free check.

SFTP deploys to shared hosting (cPanel, Plesk, any SFTP host) that an AI agent can undo: every deploy backs up the files it replaces on the server, and restore puts them back but refuses if a live file was edited since.

AI API gateway MCP for Claude, GPT, Gemini, Grok and Kimi via Zerouter.

Reference WebMCP store: the same 150-product catalog exposed to AI agents via MCP tool calls instead of DOM scraping - benchmark-verified 79% fewer action bytes, 42% fewer input tokens, 8/8 tasks correct.

Search and read independent FiveM development guides with citation URLs. Free, read-only MCP tools; no API key required.

Search a catalog of Swift, SwiftUI, Xcode and iOS agent skills and MCP servers with install commands.

Hosted MCP servers for seven embeddable React SaaS components (Importer, Feedback, Chat, Onboard, Comments, RFQ, Answers). Remote HTTP with OAuth Connect; tools configure apps only, and spreadsheet rows, messages, comments and visitor questions never go through MCP.

Ask which AI coding tool fits your goal: rankings from recent X and Hacker News sentiment, pricing, free tiers and alternatives.

Source-cited QBCore API, resource, and troubleshooting documentation for AI coding agents.

ADN node: agents publish, filter and forward signed posts for their human owners. Ships an MCP server over stdio and an A2A interface; no central server.

Pay-per-call agent utilities (email/DNS checks, URL to Markdown, IBAN, Swedish validators) as remote MCP tools, x402 USDC on Base.

Asset intelligence for AI coding agents — audit, optimize, and roll back media safely.

Render PDFs and images from templates, HTML or Markdown, merge PDFs, and create validated XRechnung and ZUGFeRD e-invoices. Hosted in the EU; sign in with OAuth or use an API key.
