To see which of them reach your code, [scan a public repository](https://since.dev/scan.md), or have your coding agent call `check_code` with your manifest or lockfile over [MCP](https://since.dev/docs.md#mcp). [The API](https://since.dev/docs.md#api) reads every change in every version, not only the newest. A fix pull request opens for the changes that reach a connected repository. Nothing merges or deploys. ## Put your code on continuous maintenance. Scan a public repository now, or give your agent one line. [Scan a repository](https://since.dev/scan.md). Any public GitHub repository. No sign-in. ### Tell your agent what changed since it was trained. `claude mcp add --transport http since https://api.since.dev/mcp` [Get an API key](https://app.since.dev/login?mode=signup) Codex, Cursor and any MCP client use https://api.since.dev/mcp. --- Every page on this site as Markdown: https://since.dev/sitemap.md.
