collectives-mcp

A Model Context Protocol server for Nextcloud Collectives — exposes collectives, pages, tags, attachments, page history, and trash to Claude and any MCP-compatible client.

How it works

The server uses two Nextcloud APIs, verified against the Collectives OpenAPI spec:

The OCS API handles structured operations and returns typed JSON. WebDAV is used only where OCS has no equivalent — primarily reading and writing page markdown content.

Install

Download collectives-mcp-0.2.1.tgz from the latest release, then:

npm install -g ./collectives-mcp-0.2.1.tgz

This installs the collectives-mcp command globally.

Configuration

Add to your MCP client config (Claude Code shown):

{
  "mcpServers": {
    "collectives": {
      "command": "collectives-mcp",
      "args": [],
      "env": {
        "NEXTCLOUD_URL": "https://your-nextcloud.example.com",
        "NEXTCLOUD_USER": "your-username",
        "NEXTCLOUD_APP_PASSWORD": "xxxx-xxxx-xxxx-xxxx-xxxx"
      }
    }
  }
}

Generate the app-password in Nextcloud under Settings > Security > Devices & sessions > "Create new app password". The MCP server only needs an app-password, never your real account password — and you can revoke it without affecting your main login.

Development

pnpm install
pnpm dev      # stdio MCP server, point mcp inspector at it
pnpm test     # integration tests against MCP_TEST_COLLECTIVE
pnpm build    # tsc -> dist/

Required env vars: NEXTCLOUD_URL, NEXTCLOUD_USER, NEXTCLOUD_APP_PASSWORD. Tests additionally need MCP_TEST_COLLECTIVE pointing at a throwaway collective.
