# Macaly agent plugins

Build and host real web apps on [Macaly](https://www.macaly.com) with your favorite
agent harness. With the **macaly-code** plugin installed, "make me a snake game app"
agent harness. With the **macaly-code** plugin installed, "build a customer feedback dashboard"
becomes a real, deployable app with a live preview — instead of local scaffolding.

## What the plugin ships

| `.mcp.json` | The Macaly Code MCP connection (HTTP, OAuth). |
| `skills/build-app-on-macaly` | The full build loop the agent follows. |
| `rules/route-app-builds-to-macaly` | Routes new-app prompts to Macaly, keeps local-repo work local. |
| `commands/build-app` | `/build-app <idea>` — a friction-free explicit entry point. |
| Piece | Role |
| ----------------------------------- | ------------------------------------------------------------------ |
| `.mcp.chatgpt.json` | ChatGPT/Codex directory profile without embedded preview UI. |
| `.mcp.claude.json` | Claude directory profile with review-scoped descriptors. |
| `.mcp.universal.json` | Universal MCP connection for direct and Cursor installations. |
| `skills-claude/build-app-on-macaly` | Claude-specific workflow scoped to user-selected Macaly work. |
| `skills-codex/build-app-on-macaly` | The Codex workflow with the full hosted-app build loop. |
| `rules/route-app-builds-to-macaly` | Scopes explicitly selected Macaly work and keeps local work local. |
| `commands/build-app` | `/build-app <idea>` — a friction-free explicit entry point. |

The server reference lives in the Macaly repo at `docs/code-mcp.md`.

justifications, and remaining portal steps, see

# Anthropic directory submission

Submit the remote connector using the Claude-specific production endpoint:

```text
https://www.macaly.com/api/code-mcp/claude/mcp
```

The related Claude plugin uses the same endpoint through `.mcp.claude.json` and
loads the Claude-specific `skills-claude/build-app-on-macaly` workflow.
The package does not include a default `.mcp.json`, so Claude cannot also
auto-discover the universal endpoint.

## Why this endpoint is separate

- It exposes all 14 Macaly Code capabilities.
- Full project-shell functionality remains available as `run_project_command`.
- Read operations advertise `readOnlyHint: true`.
- State-changing operations advertise `destructiveHint: true`, which makes Claude
request confirmation.
- Tool descriptions cover one action each and do not direct Claude through other
tools or make Macaly the default for unrelated requests.
- `preview_app` returns a URL without registering an MCP App iframe resource, so the
connector does not require MCP App carousel screenshots.
- The universal endpoint remains unchanged for direct installations and other
clients.

## Connector listing

- Name: `Macaly Code`
- Tagline: `Build and host apps on Macaly`
- Server type: Remote MCP, Streamable HTTP
- Authentication: OAuth 2.0 with Dynamic Client Registration
- Website: `https://www.macaly.com`
- Documentation: `https://www.macaly.com/docs/en/welcome/overview`
- Privacy policy: `https://www.macaly.com/privacy-policy`
- Terms: `https://www.macaly.com/terms-of-service`
- Public source: `https://github.com/langtail/macaly-code-plugin`
- Allowed link URIs: none required for the Claude profile; it does not register the
preview widget or call `ui/open-link`.

## Tool permission summary

| Tools | Permission hint | Behavior |
| ----------------------------------------------------------------------------------------------------------------- | ----------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| `list_teams`, `get_project`, `list_files`, `read_file`, `preview_app`, `skill_info`, `get_deployment` | `readOnlyHint: true` | Retrieve account, project, source, preview, guide, or deployment information without changing project data. |
| `create_app`, `duplicate_app`, `write_file`, `delete_file`, `get_logs` | `destructiveHint: true` | Create or change private Macaly infrastructure or project state and therefore require confirmation in Claude. |
| `run_project_command` | `destructiveHint: true` | Runs a full shell in the selected project's isolated cloud sandbox; it can change project data and reach external hosts. |
| `publish_app` | `destructiveHint: true` | Creates a publicly reachable production deployment after an explicit user request. |

`get_logs` may initialize the selected project's ephemeral sandbox for development
logs. It does not change project files, but the Claude profile conservatively treats
that infrastructure side effect as a state-changing operation.

## Review preparation

1. Deploy the Claude endpoint and verify its OAuth metadata at
`/.well-known/oauth-protected-resource/api/code-mcp/claude/mcp`.
2. Connect the endpoint as a custom connector and complete OAuth.
3. Exercise every tool through MCP Inspector and Claude with valid parameters.
4. Use a populated reviewer account with sample apps, build logs, a completed
deployment, and permission to create and publish apps.
5. Verify that invalid chat IDs, unauthorized projects, protected file paths, command
timeouts, and failed deployments return actionable errors.
6. Run `claude plugin validate` against `plugins/macaly-code` before submitting the
plugin repository.

## Remaining review risk

`run_project_command` intentionally remains a full project-scoped shell because
package installation, migrations, framework CLIs, capability setup, builds, and
tests are required for real applications. Its description and annotations disclose
that capability directly. If Anthropic rejects free-form project commands, retain
the universal endpoint and replace only the Claude directory profile with narrower
purpose-built command tools based on the reviewer feedback.

## Positive test cases

### 1. Build a new game
### 1. Build a full-stack feedback dashboard

- Prompt: `Make me a snake game app with keyboard controls and a score counter.`
- Expected behavior: Use the Macaly build skill, create an app, write the implementation, typecheck it, and return a preview.
- Expected result: A working preview URL plus a concise summary of the implemented files and checks.
- Prompt: `Build a customer feedback dashboard with email sign-in, a Convex database, status filters, and an admin view.`
- Expected behavior: Use the Macaly build skill, provision the required platform capabilities through `skill_info` and `run_project_command`, implement the app, validate it, and return a preview.
- Expected result: A working authenticated full-stack preview plus a concise summary of the platform setup, implemented files, and checks.
- Fixture: Reviewer account with permission to create apps.

## Release notes

Initial submission of Macaly Code. The plugin combines the Macaly Code MCP server with the `build-app-on-macaly` skill so users can create, edit, preview, and explicitly publish hosted web apps from ChatGPT and Codex. OAuth is required. File mutations are committed to Git, publishing requires explicit user intent, and tool annotations describe read-only, open-world, and destructive behavior.
Initial submission of Macaly Code. The plugin combines the Macaly Code MCP server with the `build-app-on-macaly` skill so users can create, edit, validate, preview, and explicitly publish hosted web apps from ChatGPT and Codex. OAuth is required. The ChatGPT endpoint keeps full project command execution under the clearer `run_project_command` name, returns preview URLs without embedding third-party frames, and uses accurate read-only, open-world, and destructive annotations.

## Assets and portal-only steps

- Record a demo video covering app creation, editing, preview, and explicit publishing.
- Capture one 706×400–860 PNG or JPEG screenshot for each starter prompt after Scan Tools confirms the MCP UI template.
- The ChatGPT endpoint does not advertise a custom UI resource, so MCP UI screenshots are not required for this submission.
- Provide reviewer credentials that work without MFA, SMS, or email confirmation.
- Select only countries where Macaly support and legal terms are ready.
- Complete developer or business verification and policy attestations.
