"Open Access" matching MCP servers:

Routes every Claude Code/Hermes prompt through a local LLM planner and Open-Jev probe, injecting calibrated probability context while failing open if local services are unavailable.

Enables AI agents to generate images, videos, and lip-sync media, and to query wallet balances via the Open Generative Studio instance.

Open-source MCP server for mem0 that enables memory storage and retrieval using local LLMs, self-hosted, and Docker-free.

Enables AI agents to access Cloudflare Workers AI for serverless LLM chat completions, text embeddings, and image generation via MCP tools.

MCP server providing on-demand access to official prompting guides for building robust meta-prompts.

Open-source CLI + MCP server that asks real AI engines (ChatGPT, Claude, Gemini, Perplexity) real buyer questions and scores whether a brand or its products get recommended (AI visibility / GEO / AEO). Runs locally with your own API keys.

Open-source verification for evidence-grounded AI. Runs deterministic grounding checks of AI outputs against source evidence, with no LLM judge.

Enables AI assistants to rewrite AI-styled English prose into more natural human writing, with tools for humanizing text and retrieving information about the underlying model.

Model Context Protocol server for AI Canvas. Search, inspect, and install open-source React and Tailwind components from the aicanvas.me registry directly in your AI editor.

A private, open-source AI-text checker. Get a read on whether text looks AI-written, the exact AI-tell spans to fix, a reuse check, and a grammar pass.

An open-source MCP server that rewrites AI-generated prose to appear human-authored, with tools for detection and verification against AI detectors.

Provides unified access to multiple AI providers through Vercel AI Gateway, enabling question answering, web search, multi-model research, and model listing.

MCP server that provides access to 15+ non-Claude AI models through a single API key, with PII Shield protection and 10 tools for chat, model management, pricing, and usage tracking.

Local-first MCP server that lets AI agents design Cisco-style networks and generate L1/L2/L3 topology diagrams, device tables, and AI-ready context files.

Provides free, unlimited access to Claude AI models via Puter.js for AI coding agents and IDEs through the MCP protocol.
