Api Key

Backendless is a backend-as-a-service platform for mobile and web apps, offering database, file storage, user authentication, and APIs. It helps developers ship scalable applications faster without managing server infrastructure.

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Backendless account to Claude via Composio Connect, enabling it to list all files in the user uploads folder, create a new directory for project assets, retrieve users where status is active, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Backendless to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Backendless account

Back in Claude, ask it to connect to Backendless or give it any Backendless-related task.

For example, ask Claude to:

  • "List all files in the user uploads folder"
  • "Create a new directory for project assets"
  • "Retrieve users where status is active"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Backendless account is ready to use.

What is the Backendless Claude Connector, and what's possible with it?

The Backendless MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Backendless account. It provides structured and secure access to your backend services, so your agent can perform actions like managing file storage, retrieving and updating database records, handling directories, and orchestrating server-side logic on your behalf.

  • Dynamic file and directory management: Allow your agent to create, copy, delete, and list files or folders in your Backendless storage, keeping your app data organized.
  • Database record retrieval and filtering: Empower the agent to fetch objects from specific tables with advanced filtering, sorting, and pagination for instant data access.
  • Automated backend task scheduling: Let the agent create or delete timers to run recurring or one-off server-side logic, enabling powerful backend automation.
  • Custom Hive resource management: Instruct your agent to create new Backendless Hive resources and retrieve full maps of stored values for scalable, flexible data handling.
  • Safe data cleanup: Make it easy for your agent to remove obsolete files, directories, or scheduled tasks, helping maintain a tidy and efficient backend environment.

Troubleshooting

1. Why does Claude not use the Composio connector for Backendless?

The connector can show as connected, but Claude must use it in each Backendless conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Backendless again.

2. Why does Claude show an MCP server error before Backendless connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Backendless.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Backendless.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Backendless authorization link not work?

The Composio connector is one server. Your Backendless account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Backendless connection.
  • Composio creates a fresh Backendless authorization link.
  • Open that link in your browser and finish the Backendless sign-in.

4. Why do Backendless actions fail after they worked before?

The Backendless connection can expire or lose permission.

  • Ask Claude to inspect the Backendless connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Backendless account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Backendless.
  • If the action still fails with a permission error, check that the connected account has that permission in Backendless itself.

5. How do I switch to a different Backendless account?

Claude can manage the Backendless connection for you.

  • Ask Claude to disconnect or delete the current Backendless account.
  • Ask Claude to connect Backendless again.
  • Open the new Composio authorization link for Backendless.
  • Sign in with the other Backendless account in the browser.
  • After the account connects, ask Claude to retry the Backendless task.

6. Why is my Backendless connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Backendless connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Backendless tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Backendless.

FAQ

Frequently asked questions

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

Yes, you can. Claude Cowork 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 Backendless tools.

Yes, absolutely. You can configure which Backendless 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.

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 Backendless data and credentials are handled as safely as possible.
