How to delete MCP server

Kristoffer Lersveen 0

I added an mcp to an agent, a custom one. However auth does not work as i suspect i use the wrong client secret, but i am apparently limited to having just one custom connection made. And there seems. to be no way to remove and delete a created mcp tool.

Kristoffer Lersveen You should be able to remove the MCP server configuration from your agent:

Open the agent in Copilot Studio.

Go to Build.

Under Tools, locate the MCP server.

Select the X next to it and confirm Remove.

You can also select the MCP server from the Tools list and update its authentication credentials without removing it.

Please note that removing the tool only disconnects it from this agent. It does not delete the external MCP server itself.

If this MCP integration uses a Power Platform connection, you can remove that separately:

Open Power Apps and Power Automate.

Select the same environment used by Copilot Studio.

Go to Connections.

Find the MCP/custom connector connection, select …, and then select Delete.

If the client secret was entered incorrectly, you can instead edit the MCP server authentication from the agent’s Tools dialog. For a custom connector, open Custom connectors, edit its Security settings, update the client secret, and then repair or recreate the connection.

Current documentation states that an agent can connect to multiple MCP servers. If you still see a one-connection restriction, or the Remove/Edit controls are unavailable, please provide screenshots, the selected environment, agent experience, and the exact error so this can be investigated.

Yes. A custom MCP server/tool can be removed.

For Copilot Studio agents:

Open the agent.
Go to the Tools dialog.
Use the standard tool management flow to remove the MCP server, or turn it off temporarily.
If the problem is only the URL, authentication, or exposed tools, edit the existing server entry in the same Tools dialog to refresh the connection and re-read the tool list.

If the issue is the wrong client secret, editing the server entry is the supported path when authentication changes after the server was added.

For Dynamics 365 Service Agent:

Open Service Agent and ask to enter maker mode.
Select Organization as the scope.
Open MCP server management.
Remove the server to disconnect it.

Removing an MCP server removes its tools from the agent, but it does not delete the external MCP server itself.

If the environment is enforcing a limit on available MCP connections or registrations, deleting the existing registration frees capacity. In Dynamics 365, deletion is immediate and permanent, there is no undo, and it frees a slot toward the environment registration cap.
