# Subsalt ChatGPT plugin

This portable Agent Plugins package connects ChatGPT and Codex to the public Subsalt MCP endpoint at `https://mcp.subsalt.io/mcp`.

It includes:

- `plugin.json`: package identity, listing metadata, and OpenAI-specific presentation metadata.
- `mcp.json`: Streamable HTTP MCP configuration using OAuth dynamic client registration.
- `skills/`: reusable onboarding and data-analysis workflows.

## Package a ZIP

From the repository root:

```sh
make -C plugins/subsalt package
```

The command writes `dist/subsalt-chatgpt-plugin.zip`. The archive contains one top-level `subsalt/` plugin root, suitable for local installation or as the skills/package artifact associated with a remote-MCP submission.

## Public submission

Submit the remote endpoint through the plugin submission portal's **With MCP** flow. The ZIP does not contain credentials. Before submission, follow [`SUBMISSION.md`](SUBMISSION.md), including production endpoint scanning, OAuth review, domain verification, legal listing information, and test credentials.

## Private customer deployments

This public package is not a Secure MCP Tunnel configuration. For a customer-hosted MCP server, follow [`docs/guides/chatgpt-private-mcp-tunnel.md`](../../docs/guides/chatgpt-private-mcp-tunnel.md). The customer first creates a custom MCP server in its own ChatGPT workspace using its tunnel, then can attach equivalent skills through a workspace-specific plugin configuration.
