# Polygraph (AI) Polygraph is the Nx team's answer to two limits every coding agent hits: it only sees one repository, and it forgets everything between sessions. They call it a meta-harness. It doesn't replace [[Claude Code]], [[OpenAI Codex]] or [[OpenCode]]; it wraps them with cross-repo visibility and persistent memory. Free during early access, with a promised 30-day notice before any pricing change. ## What it provides - A "synthetic monorepo": every repository you have access to (private and public) connected into one dependency graph, without moving any code. Monorepo ergonomics, no migration. Very much an Nx idea. - Recorded agent sessions. Resume, reference, or build on work done by anyone, on any machine, even with a different agent. - Session handoff with full context: repos, branches, PRs, logs - One place to follow the PRs and CI runs of a change that spans several repositories - An MCP server (`@polygraph/mcp`), a CLI, and installable skills and subagents (the `nrwl/polygraph-skills` repo) for [[Claude Code]], Codex, [[OpenCode]], GitHub Copilot, and Gemini ## Why it matters Agents are already decent inside a single repository. Real organizations don't work that way. The change that matters usually touches a shared library, an API, and three consumers living in three different repos. Polygraph treats cross-repo topology and agent memory as infrastructure instead of something each team rebuilds with CLAUDE.md files and clever prompts. The session recordings double as organizational memory: what was tried, what shipped, by whom, with which agent. The open question is trust. You're letting a third party index every private repository you have. The security story leans on Nx's existing infrastructure, and the product is young; worth watching before betting a whole organization on it. ## References - Official website: https://trypolygraph.com/ - Documentation: https://docs.trypolygraph.com/ - App: https://app.trypolygraph.com - Skills, subagents and Claude plugin: https://github.com/nrwl/polygraph-skills - MCP server: https://www.npmjs.com/package/@polygraph/mcp - Security: https://security.nx.app/ - X: https://x.com/trypolygraph - LinkedIn: https://www.linkedin.com/company/trypolygraph/about/ - Product Hunt: https://www.producthunt.com/products/polygraph ## Related - [[AI Agents]] - [[Claude Code]] - [[OpenAI Codex]] - [[OpenCode]] - [[Gemini CLI]] - [[GitHub Copilot CLI]] - [[Model Context Protocol (MCP)]] - [[GitHub]]
