Build Keeper apps from Codex or Claude Code
Turn a plain-language operational brief into a complete Keeper app, or safely improve one that is already live. The plugin combines the current Keeper contract, focused composition guidance, and approval-gated deployment tools.
One public repository. Separate packages for Codex and Claude Code.
Definitions are reviewed separately from live-record changes.
Available today from MechaBee's public Git marketplace
This is an independent distribution channel for the current Codex and Claude Code packages. Keeper App Author is not yet published in OpenAI's universal Plugins Directory. The repository is public, versioned, and can be inspected before installation.
Choose the client you use
Add the MechaBee marketplace, install Keeper App Author, and complete MechaBee OAuth when your client prompts you to sign in.
Codex
Run these commands in a terminal with the Codex CLI available.
codex plugin marketplace add MechaBee/keeper-authoring-plugins
codex plugin add keeper-app-author@mechabeeComplete OAuth when prompted, then start a new Codex task so the installed skills and Keeper tools are loaded.
Claude Code
Run these commands in a terminal with Claude Code available.
claude plugin marketplace add MechaBee/keeper-authoring-plugins
claude plugin install keeper-app-author@mechabeeComplete OAuth when prompted, then start a new Claude Code session so the plugin is loaded.
Installing from Git gives the plugin the same skills, references, branded assets, and production Keeper MCP connection included in the versioned repository.
A complete path from brief to deployed app
The plugin does more than generate files. It discovers the correct workspace, reads the current contract, builds the candidate, and keeps the deployment reviewable.
Complete candidates
Create app metadata, schemas, views, navigation, workflows, providers, and agent actions required by the approved brief.
Contract validation
Validate the entire candidate against the live Keeper contract and resolve diagnostics before deployment.
Path-level review
Preview added, changed, and removed files before preparing the exact upload.
Approval-gated apply
Apply only the staged change you reviewed, with revision checks protecting against stale writes.
Safe app evolution
Inspect and repair existing apps while preserving their live records by default.
Direct launch
Open the deployed app from the launch URL returned after a successful apply.
OAuth access stays scoped to your MechaBee account
The plugin connects to the production Keeper MCP server at mechabee.com and requests separate read and write scopes. It contains no credentials.
- Read access discovers agents, workspaces, apps, contracts, and authorized definitions.
- Write access validates, stages, and applies changes only within your available authority.
- Raw-data access and replacement require the corresponding app permission and explicit user intent.
- Passwords, access tokens, and MFA codes should never be pasted into a prompt.
What the review protects
Exact target
The agent and workspace are discovered before app operations begin.
Exact change
Prepared stages are bound to the reviewed diff and authorization.
Exact revision
Concurrency checks prevent a stale stage from silently overwriting newer work.
Operational apps, not just starter screens
Keeper App Author can compose focused personal tools and multi-table team applications from the same declarative runtime.
Data and views
Schemas, relations, records, lists, tables, boards, dashboards, details, and forms.
Workflows
Record actions, automation steps, provider actions, and agent-assisted operations.
Access
Deny-by-default app policy, app roles, row-scoped data, and authenticated sharing.
Existing apps
Inspection, definition changes, migrations, validation repairs, and safe deployment.
Refresh the marketplace before reinstalling
Published Git releases keep the Codex and Claude Code packages on the same plugin version while allowing their manifests to evolve independently.

Start with the checks below. If the problem continues, include your client, plugin version, and the non-sensitive error message when contacting MechaBee.
The plugin does not appear after installation+
Confirm the marketplace and plugin are listed in your client, then start a new task or session. Newly installed skills and tools are loaded at the start of a conversation.
OAuth did not complete+
Retry the sign-in prompt and finish it in the browser window opened by your client. Do not copy credentials into the conversation.
The plugin cannot edit an app+
Ask it to inspect the app's effective access. Definition edits, raw-data access, role changes, and data replacement require different Keeper capabilities.
A prepared deployment became stale+
Prepare the upload again and review the new diff. The plugin should never weaken the revision check or reuse a stale stage.
