Conduit is a local-first gateway that puts every MCP server behind one endpoint shared by all your AI coding tools (Claude, Cursor, VS Code, Codex, and more). Set up and authenticate each server once, then connect every client to Conduit instead of re-adding servers everywhere. Keys stay in your OS keychain (never in client configs), lazy discovery exposes just 3 meta-tools so your agent's context stays small no matter how many servers you add, and you can toggle servers on/off live without restarting the client. Proxies both local (stdio) and remote (http/SSE) servers, with a built-in audit log and tool playground. No Docker, no cloud, no account. Free and open source (MIT). Windows, macOS, and Linux.

Open-source memory for AI coding agents. Tell your agent to "remember" something in Cursor, Claude Code, Codex, or Gemini CLI, and Krimto saves it as a plain markdown file in a git repo you own — not rows in a vendor's database. Recall it later in a new chat, a different editor, or on another machine. One npx command, no account, no API key. Apache-2.0, with a user → team → org scope hierarchy so a team can share memory while personal notes stay private. Run: npx @krimto-labs/krimto init

Scout, score, and fuse 36,000+ open-source projects, papers, and ML models into defensible technology stacks. Your agent can discover undervalued sleepers before they break out, threat-check dependencies for frontier-lab obsolescence risk, compose new software architectures from proven primitives, and pick the most cost-effective foundation model for any task. Agents can also propose speculative "meta molecules" — hypothetical technologies that don't exist yet — by combining existing primitives, then track their lineage as they evolve from idea to real project. 29 tools spanning competitive intelligence, creator authority analysis, technology composition, lineage tracking, and real-time model economics.

Podcli is an open-source MCP server and CLI that turns long-form podcasts into upload-ready short clips for TikTok, YouTube Shorts, and Reels.
