GeoIP and ASN intelligence for AI agents with country, city, timezone, network ownership and ASN lookups.

Open-source self-hostable MCP server with ~1,100 deterministic tools (web search, headless Chromium, PDFs, OCR, images, ~1,040 CPU utilities). Free to self-host or pay per call via x402 (USDC on Base).

MCP tool that audits a code diff against the originating prompt and flags out-of-scope changes an AI agent made.

A community gateway to migrate legacy Jakarta EE monoliths into Spring Boot using AST parsing.

Real-time system monitoring MCP server built with Python and FastMCP - exposes CPU, memory, disk, and process metrics to any MCP-compatible AI client.

Local, on-device TTS for Claude & Cursor. No API key, no cloud. 10 voices, 31 languages, ~820ms on Apple Silicon.

Build and ship live APIs from chat. No servers to manage. Cloudgate Builder lets Claude create and run real workflow-APIs in your Cloudgate workspace. Sign in once with OAuth and your endpoints go live instantly.

A Model Context Protocol (MCP) server for creating, managing, and executing Bruno API testing collections. Supports both .bru and .yml (opencollection) formats with built-in security hardening.

Polarion ALM MCP server for Claude, Cursor & Copilot — read and write documents, work items, and traceability links

Cloud security insights, guardrail guidance, and compliance checking via Dawnguard.

Run parallel, resumable, human-operable Antigravity CLI sessions from Codex, Claude Code, or any MCP-capable agent harness.

Free WordPress MCP For Connecting AI Coding Agents

MCP server (Rust, rmcp) exposing the Apple App Store Connect API — apps, in-app purchases, subscriptions, pricing, versions/metadata, TestFlight, provisioning, and asset uploads, plus generic JSON:API tools.

BumpGuard is an MCP server for pre-flight dependency-upgrade analysis: before you bump a dependency, it reports which of your usages break, with line numbers, severity, and fix hints. It also verifies AI-written code against installed APIs to catch hallucinations. Static analysis only — never executes third-party code. Python + .NET.

Unified MCP server for Ignite UI — documentation, API, and CLI scaffolding

fable-discipline is a Claude Code plugin that makes agentic software work follow repeatable working patterns: design before code, verify after edits, separate author from reviewer, preserve verified state between sessions, and report uncertainty honestly.

Check if a command is runnable before running it.

Declarative workflow orchestration for Temporal using the CNCF Serverless Workflow specification.

MCP server for .NET runtime diagnostics — memory, GC, threads, and more.

Security and compliance layer for MCP agents. The analyze_prompt tool checks any input — user messages, RAG retrievals, tool outputs — for prompt injection (22 deterministic signatures, 7 languages) and PII before your model sees it. Every verdict returns a signed audit record (SHA-256 + UUID + UTC) you can retain as GDPR Art. 30 evidence. Free tier: 10,000 requests/month.

RepoFortify is a remote MCP server for production-readiness and security scanning. Connect it to your AI coding tool — Lovable, ChatGPT, Codex, Claude Code, Cursor, and other MCP clients — and scan your repository, review risk findings, and get AI fix plans without leaving where you build. Authentication required on every request; your data stays isolated to you.

MCP server for WordPress: connect Claude, ChatGPT, Cursor, and other AI clients to manage content, edit themes, run WP-CLI, and automate self-hosted WordPress sites.

Access STM32CubeIDE and debug tools

Pronunciation dictionary for developer jargon - IPA, respelling and audio for 1,650+ sourced entries (kubectl, nginx, JSON).

Local-first dashboard and MCP server for Claude Code and Codex token usage tracking.

RedirHub's MCP server for managing URL redirects, hosts, and domains at scale. Full CRUD + bulk operations, access logs, usage stats, and dry-run safety. 19 tools across 15 resources. Works with Claude, Cursor, and any MCP client. Free tier available.

MCP bridge that lets Claude Code delegate heavy tasks to the Antigravity CLI (agy) — purpose-built tools, model routing with fallback, session continuity, and output truncation to save Claude's context and tokens.
