Security layer for AI agents — MCP Hub with DLP, cross-agent Memory Vault, and 8.6M coding pattern database. Bidirectional content security scans outbound data for PII, secrets (50+ credential types), and high-entropy strings while blocking prompt injection inbound. Memory Vault enables persistent context across Claude, Gemini, Cursor, and Copilot with personal and team-level vaults. Pattern Database provides validated bug-fix patterns from 6,219 OSS projects across 48 languages, queryable by agents before writing code. Single endpoint proxying with built-in auth, health checks, and circuit breaking. Free tier available.

Strips PII (emails, SSNs, API keys, phone numbers, addresses) from text before agents send data to third parties. GDPR/HIPAA aligned. Stateless. Pay $0.005 USDC per scrub via x402 on Base network.

Free AI security & productivity tools — prompt injection tester, PII redactor, code sanitizer, context budget planner, model picker, and more. 6 tools available via MCP, all stateless and no auth required.

Persistent memory layer for AI agents with entity resolution, PII detection, AES-256-GCM encryption at rest, and hybrid search. Self-hosted. 100% on LoCoMo benchmark. Works with Claude Code, Cursor, VS Code, Windsurf, JetBrains, and more.

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.

Privacy-preserving agent settlement for prediction markets via blind signatures. 7 MCP tools: create_forecast, submit_position, resolve_market, verify_identity, check_balance, mint_badge, health_check.

25 read-only tools for searching, analyzing, and exploring your entire iMessage history on macOS. Spotify Wrapped for texts, conversation analytics, streaks, reactions, read receipts, and more. Everything runs locally.

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.

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
