NativeKeel for Codex

NativeKeel checks React Native and Expo projects before you change them. This plugin adds the nativekeel MCP server (scan_project, upgrade_plan, check_library, explain_error, verify_upgrade) and a skill that tells Codex when to use it: upgrading React Native or the Expo SDK, adding a native library, fixing a build, launch or store-review error, preparing a release, or before running a project you did not write.

Runs npx -y nativekeel@<version> mcp, the open-source nativekeel package pinned to an exact version (no dependencies, npm provenance). Reads project files, never writes to the project, never runs project code, never returns source code. Codex starts plugin servers in the plugin folder and does not let users set environment variables for them, so the boundary is your home folder. To limit scans to one project, use the config.toml server below instead of the plugin and set NATIVEKEEL_MCP_ROOTS in its env. Sends only package names and versions to registry.npmjs.org, reactnative.directory and unpkg.com; no telemetry.

Server limited to one project, in ~/.codex/config.toml (instead of the plugin):

[mcp_servers.nativekeel]
command = "npx"
args = ["-y", "nativekeel@latest", "mcp"]
env = { NATIVEKEEL_MCP_ROOTS = "/absolute/path/to/your/app" }
