Microsoft Advertising is Microsoft's platform for managing search advertising campaigns across Bing and partner sites. It provides campaign controls, audience targeting, bidding, and performance reporting in one place.

14 Tools

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 Microsoft Advertising account to Claude via Composio Connect, enabling it to list active campaigns with their current budgets, run a performance report for last month, update bids for underperforming ad groups, 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.

3. Connect your Microsoft Advertising account

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

For example, ask Claude to:

  • "List active campaigns with their current budgets"
  • "Run a performance report for last month"
  • "Update bids for underperforming ad groups"

It will prompt you to authenticate and authorize access.

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

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

The Microsoft Advertising MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Microsoft Advertising account. It provides structured and secure access to your customers, advertiser accounts, campaigns, ad groups, and performance reports, so your agent can find accounts, create campaigns and ad groups, update or activate advertising assets, and request performance reports on your behalf.

  • Account and customer discovery: Have your agent list accessible customers and advertiser accounts, then identify the accounts available for campaign work.
  • Campaign management: Instruct your agent to list, create, update, activate, or delete search campaigns in a Microsoft Advertising account.
  • Ad group management: Let the agent list, create, update, activate, or delete search ad groups within a campaign.
  • Performance reporting: Direct your agent to request an account performance report and check an existing report request.
  • Advertising user access: Have your agent retrieve the connected Microsoft Advertising user and review accessible customer and account roles.

Troubleshooting

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

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

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

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

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

  • 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 Microsoft Advertising.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Microsoft Advertising authorization link not work?

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

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

4. Why do Microsoft Advertising actions fail after they worked before?

The Microsoft Advertising connection can expire or lose permission.

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

5. How do I switch to a different Microsoft Advertising account?

Claude can manage the Microsoft Advertising connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Microsoft Advertising 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 Microsoft Advertising.

FAQ

Frequently asked questions

With a standalone Microsoft Advertising MCP server, the agents and LLMs can only access a fixed set of Microsoft Advertising tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Microsoft Advertising 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 Microsoft Advertising tools.

Yes, absolutely. You can configure which Microsoft Advertising 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 Microsoft Advertising data and credentials are handled as safely as possible.
