A cyber brain for your AI. It never forgets a detail, remembers exactly what you said, and learns how you work over time. Free, local, works with Cursor, Claude Code, Codex, OpenClaw, Hermes and more. MIT.

Self-hosted, secure tunnel server in Rust. Expose local HTTP/HTTPS/TCP/UDP services to the public internet via TLS-encrypted WebSocket. Open-source, pay-as-you-go managed option, MCP server for AI agents.

MCP server for SSH: let Claude Code, Codex and any MCP client run commands, transfer files and manage servers over SSH, with human approval, an encrypted vault and a live audit trail. Desktop app and CLI included.

An MCP server enabling AI assistants to interact with Anytype - your encrypted, local and collaborative wiki - to organize objects, lists, and more through natural language.

Local MCP server for Google Workspace (Gmail, Drive, Calendar, Sheets, Docs, Contacts, Tasks, Meet, Search Console, +Forms/Chat/Admin) across multiple accounts — OAuth-only, encrypted token storage, deny-by-default writes.

Open-source MCP server: encrypted local keys and state, operator approval gates, a hash-chained log.

Provides a local MCP bridge to an end-to-end encrypted personal vault, enabling connected agents to search and save memories, manage accounts and credentials, access personal information and private addresses, and honor granular user permissions.

Enables AI coding sessions across different coding tools to collaborate through end-to-end encrypted messaging, work handover, and change review, while the relay stores only ciphertext.

Share AI-generated HTML as a private, end-to-end encrypted link. Update it later at the same link.

Encrypted memory for Claude, on a server you deploy to your own Cloudflare account.

Encrypted, fully offline agentic memory. One click install, GUI w/ memory map, all OS and agents. Superior memory creation, storage and retrieval.

Enables MCP clients such as ChatGPT, Claude or Grok to search and read the user's own WhatsApp message history through a linked device. Messages are stored encrypted at rest, and access is read-only unless the optional send tool is enabled.

Enables Claude to brief self-hosted GrokBot bots through their webhook routines and then collect their replies in the same thread, with tools for waiting on replies, checking the inbox, and reading conversations. It includes a self-hosted dashboard for registering bots, managing encrypted webhook keys and tokens, and connecting Claude apps over OAuth or API tokens.

Enables AI assistants and other MCP clients to search, retrieve, and browse end-to-end encrypted contacts locally through read-only tools, decrypting data only on the user's device.

Enables coding agents on different machines to exchange end-to-end encrypted messages through a shared, self-hosted relay, exposing inboxes, room history, and notifications to Claude Code, Codex, or any MCP client. Peers' messages arrive automatically as clearly framed untrusted data, so collaborators can coordinate without granting tool, file, or command access.

Enables AI agents to execute commands and read files or directories on pre-registered, fingerprint-verified SSH hosts by alias or IP, while keeping encrypted passwords local and inaccessible to the agent.

Enables models to query a user's Genshin Impact Battle Chronicle through read-only MCP tools, covering account statistics, characters, artifacts, Spiral Abyss, Imaginarium Theater, and exploration progress. It uses per-user encrypted HoYoLAB cookies and works with Open WebUI, Claude Code, Codex, and opencode.

Enables AI agents to remember people, projects, places, and topics across conversations under a strict token budget, returning compact handles with expandable details while preserving changes, provenance, and encrypted self-hosted storage.

Oracle: standalone multichain agent control plane with an optional encrypted, loopback-only self-hosted signer.
