The Ferrite Agent Plugin gives an agent three coordinated tools: a skill that explains the correct workflow, a pinned Ferrite CLI, and a stateless HTTP MCP connection for remote platform operations.
Install the plugin
codex plugin marketplace add iGentAI/ferrite-labs
codex plugin add ferrite@ferrite-labs
That installs the Ferrite skill and MCP connection from the company marketplace. The skill installs its checksum-pinned CLI the first time a local workflow needs it, after asking for permission to write the user-owned binary.
For a single command:
codex plugin marketplace add iGentAI/ferrite-labs && codex plugin add ferrite@ferrite-labs
Then configure an account without placing a bearer token in the plugin:
ferrite login --ephemeral
ferrite account
You can also download the portable plugin bundle and inspect its checksum ledger.
Open the Ferrite Dashboard to see the apps and deployments created by the CLI or MCP.
What the plugin configures
| Part | Purpose |
|---|---|
| Ferrite skill | Routes local development to the CLI and compact remote work to MCP |
mcp.json | Connects to the streamable HTTP Ferrite MCP endpoint |
| CLI archive | Installs a pinned platform-compatible binary without root access |
| Install scripts | Verify checksum, version, archive paths, and ownership before writing |
The installer writes atomically to a user-owned bin directory. Uninstall removes
only a binary recorded as plugin-owned; it will not delete an unrelated
ferrite executable.
How agents should use it
- Use the CLI for
new,add, source edits,check,test,dev, preview, deploy, logs, and multi-step lifecycle operations. - Use MCP for account and app discovery, focused remote reads, and one bounded control-plane mutation.
- Do not rebuild a CLI workflow as a long chain of MCP calls.
- Treat missing CLI, version mismatch, missing login, and denied authority as different errors with different recovery commands.
Verify an installation
node scripts/validate-ferrite-plugin.mjs plugins/ferrite
scripts/test-ferrite-plugin.sh
devx-eval plugin-check --marketplace iGentAI/ferrite-labs \
--output plugin-check.json
The validation checks schema, checksums, archive containment, supported platforms, repeat installation, safe uninstall, authentication behavior, and fresh-client discovery. A valid bundle does not imply a successful account login or application deployment; verify those separately.
