HOL Guard

Newsecurity & governanceOpen source + cloud

HOL Guard is a free, open-source (Apache-2.0), local-first security layer for AI coding agents such as Claude Code, Codex, Cursor and GitHub Copilot CLI. On supported integrations it checks risky shell commands, reads of secret-bearing files, package installs and new or changed MCP tools before they run, lets you allow, ask or block each action, and keeps a local record for review. It installs with pipx (hol-guard) and works offline; optional Guard Cloud adds synced approvals, team policy and dashboards.

Agent Tincan

Newagent infraOpen source

Agent Tincan lets your AI agents (Claude Code, Codex, Gemini, Hermes, ChatGPT and others) ask each other to do things and hand back results through a small relay on your own Tailscale network, with no open ports or API keys between agents.

Graphicle

Newmemory & RAGOpen source

Graphicle, from KarLex AI, is a single local Rust program that gives Claude Code, Cursor, Codex and other MCP agents a code graph and memory, returning excerpts with file and line references from your code, docs and past sessions, with no account or telemetry.

remotify-mcp

NewMCP serversOpen source

remotify-mcp is a free, open-source (Apache-2.0) local stdio MCP server (npx remotify-mcp) that gives Claude Code, Cursor, Codex, OpenCode, Gemini CLI and other MCP hosts a remote_exec tool for running shell commands on a remote computer through an HTTP relay. The remote machine needs only curl and bash (no SSH port or installed agent), and each command can wait for human approval or run automatically.
