App: Context Agent (context_agent) — Nextcloud latest Administration Manual latest documentation

# App: Context Agent (context_agent)

The context_agent app is the app that provides AI agent functionality in Nextcloud’s “Chat with AI” feature and acts as a backend for the Nextcloud Assistant app. Nextcloud can provide customer support upon request, please talk to your account manager for the possibilities.

When the Context Agent app is installed the AI Chat in Nextcloud Assistant will be able to interact with your Nextcloud apps via virtual integrations that are called “tools”. They allow the Assistant to perform actions in your Nextcloud upon sending instructions in a chat message. Tool groups are only available if their requirements are met. They can be en- and disabled in the AI admin settings.

## Custom Tools using MCP

Model Context Protocol (MCP) is a protocol that enables Large Language Models (LLMs) to interact with external data sources and tools. The Context Agent app allows administrators to extend its capabilities by adding custom services via MCP. This can be configured in the admin settings under “MCP Config,” where you can provide a JSON configuration in the following format:

    {
      "service-name": {
        "url": "https://service-url.com/endpoint",
        "transport": "streamable_http"
      }
    }

## Requirements

- This app is built as an External App and thus depends on AppAPI v3.1.0 or higher

- Nextcloud AIO is supported

- No GPU is necessary for Context Agent but one might be useful if you use it with a self-hosted provider like llm2

- CPU Sizing

  > - At least 1GB of system RAM

## Installation

0. Make sure the Nextcloud Assistant app is installed

1. Install AppAPI and setup a Deploy Demon

2. Install the “Context Agent” ExApp via the “Apps” page in the Nextcloud web admin user interface

3. Install a text generation backend like llm2 or integration_openai via the “Apps” page in Nextcloud

### Model requirements

This app requires underlying Large language models to support tool calling. The default model in llm2 does support tool calling since version 2.4.0. Other models that may give good results are:

- Google Gemma 3 12B or higher

- Mistral 3 small 24B

- Qwen 2.5 8B or higher (May not work well with languages other than English)

- Watt Tool 8B or higher

See llm2 documentation on how to configure alternate models.

## Using Nextcloud MCP Server

Context Agent exposes an MCP server that can be used by other large language models or applications to access the tools provided by Context Agent. The server will be available at https://your-nextcloud-domain.com/index.php/apps/app_api/proxy/context_agent/mcp/, and it requires authentication via an app password passed in the Authorization header. Ex: Authorization: Bearer <app-password>.

## Scaling

It is currently not possible to scale this app, we are working on this.

## App store

You can also find the app in our app store, where you can write a review: https://apps.nextcloud.com/apps/context_agent

## Repository

You can find the app’s code repository on GitHub where you can report bugs and contribute fixes and features: https://github.com/nextcloud/context_agent

Nextcloud customers should file bugs directly with our Support system.

## Known Limitations

- Make sure to test the language model you are using in concert with this app for whether they meet the use-case’s quality requirements

- Most models have difficulties with languages other than English. Some models sometimes answer in a different language than the one used by the user.

- Customer support is available upon request, however we can’t solve false or problematic output, most performance issues, or other problems caused by the underlying model. Support is thus limited only to bugs directly caused by the implementation of the app (connectors, API, front-end, AppAPI). We still try to optimize this as far as possible, so if you encounter any false or problematic output, you can report it in a dedicated Github issue to help us improve this app.

- When multiple MCP services are configured that have tools with the same name undefined behavior will occur.

- Only remote MCP services are supported (streamable_http transport).

- MCP services that require different access tokens for each user are not currently supported.
