Dynamics 365 is Microsoft's platform combining CRM, ERP, and productivity apps. It streamlines sales, marketing, service, and operations in one place.

Introduction

Muse is Meta's AI assistant. It can connect to outside tools through custom connectors, which use the Model Context Protocol (MCP).

This guide explains how to connect Dynamics365 to Muse using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a custom connector once, then ask Muse to work with Dynamics365 in plain language.

Why use Composio?

  • Cross-app workflows across 1,500+ apps from a single plugin layer.
  • On-demand tool loading so Muse only loads the tools needed for the current task.
  • Programmatic tool calling through a remote workbench for complex, multi-step workflows.
  • Multi-account support so users can connect and switch between multiple accounts for the same app.
  • Shared account access so teams or agents can work through common business accounts and service connections.
  • Managed authentication with OAuth handling, credential storage, and token refresh managed by Composio.
  • Safer credential handling so app credentials stay outside the model context and tool responses.
  • User-level account isolation so actions run against the correct connected account instead of mixing user access.

Connecting Dynamics365 to Muse

You add Composio to Muse once as a custom connector, then connect Dynamics365 from the chat.

1. Ask Muse to connect to Composio

Start a new Muse chat and send this message. Muse builds the connector and shows a button to add your API key.

bash
Create a Custom Connector for the Composio remote MCP server and connect to it:
- Name: Composio
- Transport: remote streamable HTTP
- URL: https://connect.composio.dev/mcp
- Auth: API key sent in the x-consumer-api-key header
Open the secure credentials store so I can enter the API key there, not in this chat. Then list its tools to confirm the connection works.

2. Copy your API key

Open the Muse page in your Composio dashboard and copy your API key. It starts with ck_.

Don't paste it into the chat. It goes in Muse's secure credentials store in the next step.

3. Add your API key in the secure credentials store

Tap the button Muse shows to open Add custom connector, paste your API key, then tap Add. Muse lists the Composio tools once it connects.

Muse secure credentials store with the connect.composio.dev URL, an API Key field, and the Add button

4. Connect your Dynamics365 account

Back in the chat, ask Muse to connect to Dynamics365 or give it any Dynamics365 task.

For example, ask it to:

  • "Create a new sales lead for Acme Corp"
  • "List all open invoices for this quarter"
  • "Add a support case for a specific customer"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Muse, and your Dynamics365 account is ready to use.

What is the Dynamics365 MCP server, and what's possible with it?

The Dynamics 365 MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Dynamics 365 account. It provides structured and secure access to your CRM records, so your agent can create accounts and contacts, manage leads and opportunities, handle customer cases, and process invoices and sales orders on your behalf.

  • Account and contact creation: Have your agent create new customer accounts and contact records in Dynamics 365.
  • Lead and opportunity management: Let the agent create leads and opportunities, retrieve lead details, list all leads, and update records as deals progress.
  • Customer case handling: Direct your agent to open new customer cases and update existing cases as issues move toward resolution.
  • Invoice management: Instruct your agent to create invoices, retrieve individual invoices or a full invoice list, and update invoice details.
  • Sales order processing: Have your agent create sales orders and update them when order information changes.

Way Forward

Now that Dynamics365 is connected, extend your setup by connecting the other apps you already use every day, so Muse can run true cross-app workflows end to end.

  • Connect Calendar to turn threads into scheduled meetings automatically.
  • Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
  • Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
  • Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.

Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, Muse can coordinate multiple tools safely and reliably in one conversation.

Troubleshooting

1. Why doesn't Muse show a button to add my API key?

Muse shows the button only when you ask it to open the secure credentials store.

  • Start a new chat.
  • Send the message from step 1 exactly as written.
  • If Muse asks for the key in the chat, do not paste it. Ask Muse to open the secure credentials store.

2. Why does the Composio connection fail after I add my API key?

The key or the connector settings are not correct.

  • Copy the full key from the Composio dashboard. It starts with ck_.
  • Make sure the URL is https://connect.composio.dev/mcp and the header is x-consumer-api-key.
  • Remove the Composio connector in Muse settings, then do steps 1 to 3 again.

3. Why doesn't Muse use the Composio tools for Dynamics365?

Muse may not pick the Composio connector for the request.

  • Ask Muse to list its Composio tools.
  • Name Composio and Dynamics365 in your request, for example: Use Composio to connect to Dynamics365.
  • If it still does not work, start a new chat and try again.

4. Why does Muse ask me to connect Dynamics365 again?

Your Dynamics365 connection expired or was removed.

  • Open the link Muse gives you and sign in to Dynamics365 again.
  • Check that the Dynamics365 connection shows as ACTIVE in the Composio dashboard.

5. What do I do if I pasted my API key into the chat?

Treat the key as exposed.

  • Create a new API key in the Composio dashboard and delete the old one.
  • Add the new key in Muse's secure credentials store, not in the chat.
