## Plugin MCP alignment (Agent Guard)

On every Cursor agent `sessionStart`, the plugin runs `npx @jfrog/agent-guard --align-mcp-json` against **this plugin’s own** `mcp.json` (not project/user `.cursor/mcp.json`, and not other plugins). Stdio MCP entries are rewritten to launch through Agent Guard; remote `url` / `http` / `sse` / `ws` entries are left unchanged. If the file is rewritten, use **Developer: Reload Window** so Cursor reloads MCP config.

Disable with `JF_AGENT_ALIGN_MCP_JSON_DISABLE=1`. Optional: set `JFROG_AGENT_GUARD_REPO` to your private npm registry for `@jfrog/agent-guard`, and `JFROG_AGENT_GUARD_VERSION` to pin or override the package version. Pass `JF_PROJECT` / `JFROG_PROJECT` and optionally `JF_SERVER` / `JFROG_SERVER_ID` so align does not depend solely on jf CLI / setup.json resolution.
