ComplyMe.AI MCP server provides legal & data protection risk analysis and audits.

Strata is a self hosted AI memory server. Your AI remembers everything across every session, on your own hardware. Key features: . Semantic search (find memories by meaning, not keywords) . Per-agent API keys with granular permissions . 3D constellation viewer with live agent activity . File vault (attach real documents to memories) . CSV audit log (full transparency on every agent action) . Pre-Strata history import (your memory doesn't start at install day) . Global MCP kill switch (emergency brake, only a human can undo) . Automatic deduplication . 10 structured thought types . Backend using PostgreSQL . Runs on a Raspberry Pi Always on, always local, always yours.

CodeCompass: AI-powered Vibe Coding with MCP. Connects Git repositories to AI assistants like Claude, using Ollama for privacy or OpenAI for cloud. Integrates with VSCode, Cursor, and more.

Transform natural language into beautiful, interactive data visualizations. This server uniquely integrates powerful technologies like DuckDB, Ollama, and Plotly, streamlining complex data analysis workflows into a single, conversational experience within the Model Context Protocol (MCP) ecosystem. It addresses the fragmented workflow common in current MCP setups by providing seamless workflow orchestration, intelligent database switching, integrated statistical insights, and complete privacy-focused analytics through local Ollama processing.

Vault Tools is a privacy-first MCP server that gives your AI coding agent local file conversion and developer utility tools. Process images (format conversion, compression, resizing, EXIF stripping), manipulate PDFs (merge, split, rotate, page extraction), transform data formats (JSON, CSV, YAML, TOML, Base64, URL encoding), and generate hashes (SHA-256, SHA-512), all on your machine. Files are processed locally and never uploaded to any server or passed into the AI's context window, only file paths and metadata are exchanged.

Fully decentralized P2P web search engine for LLMs. No API key, no billing, unlimited free search via MCP. Crawls, indexes, and searches the web through a peer-to-peer network. Features offline local search, credit-based incentives, privacy-first design, and 5 MCP tools: search, search_local, fetch_page, crawl_url, network_stats.

Manage Pi-hole with the power of AI A Pi-hole MCP (Model Control Protocol) server implemented in Java that allows AI applications to interact with and manage a Pi-hole instance through standard commands.

Mobile proxies, Non-VoIP SMS verifications, and global eSIM data plans for AI agents and MCP clients. 18 tools for renting phone numbers, purchasing mobile proxies, buying eSIM data plans, and managing crypto wallet deposits.

Ra Pay AI is the first AI native payment primitive for AI Agents that uses CLI as its distribution layer and a MCP server for AI Agent automation while keeping humans in control. Ra Pay AI's terminal architecture delivers superior privacy, AI token costs and reduced prompt injection attack surface compared to browser GUI based AI Agent payment applications. Yes, we just solved AI Payments using the terminal as our distribution layer. We did it first. For every computer on earth. Use Ra Pay AI to keep an eye on your payment privacy and your AI token costs. Join us. npm install -g @rapay/cli

BitAtlas is a next-generation cloud storage platform designed with privacy and AI agents in mind. It provides a secure, zero-knowledge environment where your most sensitive documents are encrypted client-side and accessible only to you and the agents you authorize.
