Introduction

OpenClaw is the fastest growing agent harness out there, which can work 24/7 to automate almost any kind of tasks. However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Sevdesk with authentication management handled for you. You can execute actions on Sevdesk via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer.

Why use Composio?

Apart from a managed and hosted MCP server, you will get:

  • Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
  • Handling Large tool responses out of LLM context to minimize context rot.
  • Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.

How to install Sevdesk with OpenClaw

Using Composio API Key and Setup Prompt

Copy the setup prompt from the OpenClaw dashboard
  • Run it in your OpenClaw chat interface.
  • Authenticate Sevdesk from the dashboard
  • Go back to your OpenClaw interface and start asking questions.

Using OpenClaw/Composio Plugin

1. Install OpenClaw Composio plugin

bash
openclaw plugins install @composio/openclaw-plugin

2. Copy the API Key from dashboard.composio.dev

3. Setup OpenClaw Config

bash
openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"

4. Restart OpenClaw

bash
openclaw gateway restart

5. Go to your chat interface and start asking questions.

6. When prompted, authenticate the app and you're all set.

How It Works

The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.

If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.

What is the Sevdesk MCP server, and what's possible with it?

The Sevdesk MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Sevdesk account. It provides structured and secure access to your accounting workspace, so your agent can perform actions like managing invoices, tracking expenses, generating reports, organizing contacts, and handling payments on your behalf.

  • Invoice creation and management: Instantly generate, send, and track invoices for your clients, keeping your business cash flow streamlined.
  • Expense tracking and categorization: Let your agent record and organize expenses, ensuring your books are always up to date and categorized for tax time.
  • Financial reporting and insights: Request detailed reports and summaries—like profit and loss or balance sheets—so you can make informed business decisions quickly.
  • Contact and customer management: Effortlessly add, update, or retrieve customer details and supplier information to keep your records accurate.
  • Payment and transaction handling: Enable your agent to log payments, match transactions, and help reconcile your accounts, reducing manual entry and errors.

FAQ

What are the differences in Tool Router MCP and Sevdesk MCP?

With a standalone Sevdesk MCP server, the agents and LLMs can only access a fixed set of Sevdesk tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Sevdesk and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with OpenClaw?

Yes, you can. OpenClaw fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Sevdesk tools.

Can I manage the permissions and scopes for Sevdesk while using Tool Router?

Yes, absolutely. You can configure which Sevdesk scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Sevdesk data and credentials are handled as safely as possible.
