Documentation — Installation, deployment, usage across the API, CLI, and MCPinterfaces, and guidance for provisioning the backing Nextcloud instance aremaintained in the official documentation.

Overview

Nextcloud Agent is a production-grade Agent and Model Context Protocol (MCP) server designed to interface directly with Nextcloud MCP Server for Agentic AI!.

Key Features

• Consolidated Action-Routed MCP Tools: Minimizes token overhead and eliminates tool bloat in LLM contexts by grouping methods into optimized, togglable tool modules.
• Enterprise-Grade Security: Comprehensive support for Eunomia policies, OIDC token delegation, and granular execution context tracking.
• Integrated Graph Agent: Built-in Pydantic AI agent supporting the Agent Control Protocol (ACP) and standard Web interfaces (AG-UI).
• Native Telemetry & Tracing: Out-of-the-box OpenTelemetry exports and native Langfuse tracing.

CLI or API

This agent wraps the Nextcloud MCP Server for Agentic AI! API. You can interact with it programmatically or via its integrated execution entrypoints.

Detailed instructions on how to use the underlying API wrappers, extended schema bindings, and developer SDK references are maintained in docs/index.md.

MCP

This server utilizes dynamic Action-Routed tools to optimize token overhead and maximize IDE compatibility.

Available MCP Tools

Condensed action-routed tools (default — MCP_TOOL_MODE=condensed)

Verbose 1:1 API-mapped tools (MCP_TOOL_MODE=verbose or both)

5 action-routed tool(s) (default) · 27 verbose 1:1 tool(s). Each is enabled unless its <DOMAIN>TOOL toggle is set false; MCP_TOOL_MODE selects the surface (condensed default · verbose 1:1 · both). Auto-generated — do not edit.

Detailed tool schemas, parameter shapes, and validation constraints are preserved in docs/mcp.md.

Dynamic Tool Selection & Visibility

This MCP server supports dynamic toolset selection and visibility filtering at runtime. This allows you to restrict the set of exposed tools in order to prevent blowing up the LLM's context window.

You can configure tool filtering via multiple input channels:

• CLI Arguments: Pass --tools or --toolsets (or their disabled counterparts --disabled-tools and --disabled-toolsets) during startup.
• Environment Variables: Define standard environment variables:
  • MCP_ENABLED_TOOLS / MCP_DISABLED_TOOLS
  • MCP_ENABLED_TAGS / MCP_DISABLED_TAGS
• HTTP SSE Request Headers: Pass custom headers during transport initialization:
  • x-mcp-enabled-tools / x-mcp-disabled-tools
  • x-mcp-enabled-tags / x-mcp-disabled-tags
• HTTP SSE Request Query Parameters: Append query parameters directly to your transport connection URL:
  • ?tools=tool1,tool2
  • ?tags=tag1

When query strings or parameters are supplied, an LLM-free Knowledge Graph resolution layer (using DynamicToolOrchestrator) matches query intents against known tool tags, names, or descriptions, with safe fallback and automated 24-hour background cache refreshing.

MCP Configuration Examples

Install the slim [mcp] extra. All examples below installnextcloud-agent[mcp] — the MCP-server extra that pulls only the FastMCP /FastAPI tooling (agent-utilities[mcp]). It deliberately excludes the heavyagent runtime (the epistemic-graph engine, pydantic-ai, dspy, llama-index,tree-sitter), so uvx/container installs are dramatically smaller and faster.Use the full [agent] extra only when you need the integrated Pydantic AI agent(see Installation).

stdio Transport (Recommended for local IDEs e.g., Cursor, Claude Desktop)

Configure your IDE's mcp.json to launch the MCP server via uvx:

{
  "mcpServers": {
    "nextcloud-agent": {
      "command": "uvx",
      "args": [
        "--from",
        "nextcloud-agent[mcp]",
        "nextcloud-mcp"
      ],
      "env": {
        "NEXTCLOUD_URL": "your_nextcloud_url_here",
        "NEXTCLOUD_USERNAME": "your_nextcloud_username_here",
        "NEXTCLOUD_PASSWORD": "your_nextcloud_password_here"
      }
    }
  }
}

Streamable-HTTP Transport (Recommended for production deployments)

Configure your client's mcp.json to launch the Streamable-HTTP server via uvx with explicit host and port definition:

{
  "mcpServers": {
    "nextcloud-agent": {
      "command": "uvx",
      "args": [
        "--from",
        "nextcloud-agent[mcp]",
        "nextcloud-mcp"
      ],
      "env": {
        "TRANSPORT": "streamable-http",
        "HOST": "0.0.0.0",
        "PORT": "8000",
        "NEXTCLOUD_URL": "your_nextcloud_url_here",
        "NEXTCLOUD_USERNAME": "your_nextcloud_username_here",
        "NEXTCLOUD_PASSWORD": "your_nextcloud_password_here"
      }
    }
  }
}

Alternatively, connect to a pre-deployed remote or local Streamable-HTTP instance:

{
  "mcpServers": {
    "nextcloud-agent": {
      "url": "http://localhost:8000/nextcloud-agent/mcp"
    }
  }
}

Deploying the Streamable-HTTP server via Docker:

docker run -d \
  --name nextcloud-agent-mcp \
  -p 8000:8000 \
  -e TRANSPORT=streamable-http \
  -e PORT=8000 \
  -e NEXTCLOUD_URL="your_value" \
  -e NEXTCLOUD_USERNAME="your_value" \
  -e NEXTCLOUD_PASSWORD="your_value" \
  knucklessg1/nextcloud-agent:mcp

The :mcp tag is the slim MCP-server image (built fromdocker/Dockerfile --target mcp, installing nextcloud-agent[mcp]). The default:latest tag is the full agent image (--target agent, nextcloud-agent[agent])which also bundles the Pydantic AI agent and the epistemic-graph engine — use itwhen you run nextcloud-agent (the agent), not just the MCP server. SeeContainer images.

Additional Deployment Options

nextcloud-agent can also run as a local container (Docker / Podman / uv) or beconsumed from a remote deployment. TheDeployment guide has full, copy-pastemcp_config.json for all four transports — stdio, streamable-http,local container / uv, and remote URL:

• Local container / uv — launch the server from mcp_config.json via uvx,docker run, or podman run, or point at a local streamable-http container by url.
• Remote URL — connect to a server deployed behind Caddy athttp://nextcloud-mcp.arpa/mcp using the "url" key.

Agent

This repository features a fully integrated Pydantic AI Graph Agent. It communicates over the Agent Control Protocol (ACP) and interacts seamlessly with the Agent Web UI (AG-UI) and Terminal interface.

Running the Agent CLI

To start the interactive command-line agent:

# Set credentials
export NEXTCLOUD_URL="your_value"
export NEXTCLOUD_USERNAME="your_value"
export NEXTCLOUD_PASSWORD="your_value"

# Run the agent server
nextcloud-agent --provider openai --model-id gpt-4o

Docker Compose Orchestration

The following docker/agent.compose.yml configures the Agent, Web UI, and Terminal Interface together:

Security & Governance

Built directly upon the enterprise-ready agent-utilities core, standard security parameters are fully supported:

Access Control & Policy Enforcement

• Eunomia Policies: Fine-grained, policy-driven tool authorization. Supports none, local embedded (mcp_policies.json), or centralized remote modes.
• OIDC Token Delegation: Compliant with RFC 8693 token exchange for flowing authenticating user credentials from Web UI / ACP → Agent → MCP.
• Scoped Credentials: Execution context runs restricted to the specific caller identity.

Runtime Security Grid

Environment Variables

Package environment variables

Inherited agent-utilities variables (apply to every connector)

20 package + 14 inherited variable(s). Auto-generated from .env.example + the shared agent-utilities set — do not edit.

Every variable the server reads, grouped by purpose. See .env.examplefor a copy-paste starting point.

Connection & Credentials

MCP server / transport

Tool toggles

Each action-routed tool can be disabled individually via its toggle env var (set to false):FILESTOOL, USERTOOL, SHARINGTOOL, CALENDARTOOL, CONTACTSTOOL. See theAvailable MCP Tools table above.

Telemetry & governance

Installation

Pick the extra that matches what you want to run:

# MCP server only (recommended for tool hosting — slim deps)
uv pip install "nextcloud-agent[mcp]"

# Full agent runtime (Pydantic AI + epistemic-graph engine)
uv pip install "nextcloud-agent[agent]"

# Everything (development)
uv pip install "nextcloud-agent[all]"      # or: python -m pip install "nextcloud-agent[all]"

Container images (:mcp vs :agent)

One multi-stage docker/Dockerfile builds two right-sized images, selected by --target:

docker build --target mcp   -t knucklessg1/nextcloud-agent:mcp    docker/   # slim MCP server
docker build --target agent -t knucklessg1/nextcloud-agent:latest docker/   # full agent

docker/mcp.compose.yml runs the slim :mcp server; docker/agent.compose.yml runs theagent (:latest) with a co-located :mcp sidecar.

Knowledge-graph database (epistemic-graph)

The full agent ([agent] / :latest) embeds the epistemic-graph engine (pulled intransitively via agent-utilities[agent]). For production — or to share one knowledge graphacross multiple agents — run epistemic-graph as its own database container and point theagent at it instead of embedding it. Deployment recipes (single-node + Raft HA), connectionconfig, and the full database architecture (with diagrams) are documented in theepistemic-graph deployment guide.The slim [mcp] server does not require the database.

Deploy with agent-os-genesis

This package can be provisioned for you — skill-guided — by the agent-os-genesisuniversal skill (its single-package deploy mode): it picks your install method, seedssecrets to OpenBao/Vault (or .env), trusts your enterprise CA, registers the MCPserver, and verifies it — the same machinery that stands up the whole Agent OS, narrowedto just this package. Ask your agent to "deploy nextcloud-agent with agent-os-genesis".

Secrets are read-existing + seeded via vault_sync — you are only prompted for what's missing.
