## About

# oCIS MCP Server

[](LICENSE) [](https://kiteworks.com/opensource) [](https://hub.docker.com/r/owncloud/ocis-mcp-server)

A standalone Model Context Protocol (MCP) server written in Go that exposes ownCloud Infinite Scale as a set of 80+ AI-accessible tools. It enables AI assistants such as Claude, Ollama, and other MCP-compatible clients to manage oCIS users, groups, spaces, files, shares, and more through natural language, communicating exclusively over the public oCIS APIs (LibreGraph, WebDAV, OCS).

## Getting Started

See the **[Getting Started Guide](GETTING_STARTED.md)** for a full walkthrough.

### Quick Setup

```bash
# Build
make build

# Configure
export OCIS_URL=https://your-ocis-instance.example.com
export OCIS_ACCESS_TOKEN=your-token

# Run
./ocis-mcp-server
```

### Docker

```bash
make docker-build
docker run -e OCIS_URL=... -e OCIS_ACCESS_TOKEN=... owncloud/ocis-mcp-server
```

### Run Tests

```bash
make test
make lint
```

## Part of ownCloud Infinite Scale

This MCP server is an external integration for [oCIS](https://github.com/owncloud/ocis). It communicates over the public API surface and has no dependency on oCIS internals, allowing independent versioning and release cycles.

## Tool Inventory

The server exposes 80 tools in 13 categories:

| Category | Tools | Examples |
|---|---|---|
| **Users** | 6 | `ocis_list_users`, `ocis_create_user`, `ocis_get_me` |
| **Groups** | 7 | `ocis_list_groups`, `ocis_create_group`, `ocis_add_group_member` |
| **Spaces** | 14 | `ocis_list_spaces`, `ocis_create_space`, `ocis_invite_to_space` |
| **Files** | 14 | `ocis_list_files`, `ocis_upload_file`, `ocis_download_file`, `ocis_move_file` |
| **Shares** | 11 | `ocis_create_share`, `ocis_create_link`, `ocis_list_shared_by_me` |
| **Search** | 2 | `ocis_search`, `ocis_search_by_tag` |
| **Notifications** | 2 | `ocis_list_notifications`, `ocis_delete_notification` |
| **Settings** | 3 | `ocis_list_roles`, `ocis_assign_role` |
| **App Tokens** | 3 | `ocis_list_app_tokens`, `ocis_create_app_token` |
| **Admin** | 4 | `ocis_health_check`, `ocis_get_version`, `ocis_get_capabilities` |
| **Education** | 5 | `ocis_list_education_schools`, `ocis_create_education_user` |
| **OCM** | 4 | `ocis_ocm_create_share`, `ocis_ocm_list_received` |
| **Workflows** | 5 | `ocis_upload_and_share`, `ocis_create_project_space` |

### Authentication

**App Tokens (recommended):** Create in the oCIS web UI under Settings > Security > App tokens.

```bash
export OCIS_MCP_OCIS_URL="https://ocis.example.com"
export OCIS_MCP_APP_TOKEN_USER="admin"
export OCIS_MCP_APP_TOKEN_VALUE=""
```

**OIDC (alternative):**

```bash
export OCIS_MCP_AUTH_MODE="oidc"
export OCIS_MCP_OIDC_ACCESS_TOKEN=""
```

### Key Environment Variables

| Variable | Required | Description |
|---|---|---|
| `OCIS_MCP_OCIS_URL` | Yes | Base URL of the oCIS instance |
| `OCIS_MCP_TRANSPORT` | No | `stdio` (default) or `http` |
| `OCIS_MCP_HTTP_ADDR` | No | Listen address for HTTP transport (default `127.0.0.1:8090`) |
| `OCIS_MCP_HTTP_SECRET` | No* | Shared secret required as `Authorization: Bearer ` on `/mcp`. *Required when the HTTP transport binds a non-loopback address. |
| `OCIS_MCP_LOG_LEVEL` | No | `debug`, `info`, `warn`, `error` |

### Securing the HTTP transport

The HTTP transport runs every tool with the server's configured oCIS credential (often an
admin app token). The `/mcp` endpoint therefore controls the full tool inventory, so it must
not be reachable by untrusted callers.

- **Authenticate callers.** Set `OCIS_MCP_HTTP_SECRET` to a long random value. The server then
  requires `Authorization: Bearer ` on every `/mcp` request and rejects others with
  `401`. Configure your MCP client to send that header.
- **Non-loopback binds require a secret.** When `OCIS_MCP_TRANSPORT=http` binds a non-loopback
  address (for example `0.0.0.0:8090`, a routable IP, or a bare `:8090`) and no
  `OCIS_MCP_HTTP_SECRET` is set, the server refuses to start. Binding the default
  `127.0.0.1:8090` without a secret is allowed but logs a warning, because any local process
  could otherwise drive the tools.
- **Terminate TLS and restrict the network.** Front the server with TLS (a reverse proxy) and
  limit reachability with firewall / network policy; do not expose `/mcp` directly to the
  internet.
- **Prefer `stdio`** (the default) for single-client, local use such as Claude Desktop — it has
  no network listener.

### MCP Resources and Prompts

5 read-only resources (`ocis://capabilities`, `ocis://version`, `ocis://sharing-roles`, `ocis://drive-types`, `ocis://auth-mode`) and 4 guided workflow prompts (`ocis_onboard_user`, `ocis_migrate_files`, `ocis_audit_space`, `ocis_share_report`).
