Atlassian Remote MCP Server - Microsoft Copilot Studio compatibility

Vanessa Soto Lobos

Hi everyone,

I'm trying to integrate the Atlassian Remote MCP Server with a third-party MCP client and I'm looking for some clarification regarding official support and OAuth configuration.

According to the documentation, the server exposes:

• MCP endpoint: <a href="https://mcp.atlassian.com/v1/mcp/auth" target="_blank" rel="nofollow noopener noreferrer">https://mcp.atlassian.com/v1/mcp/auth</a>

• Authorization endpoint: <a href="https://mcp.atlassian.com/v1/authorize" target="_blank" rel="nofollow noopener noreferrer">https://mcp.atlassian.com/v1/authorize</a>

• Token endpoint: <a href="https://cf.mcp.atlassian.com/v1/token" target="_blank" rel="nofollow noopener noreferrer">https://cf.mcp.atlassian.com/v1/token</a>

• Registration endpoint: <a href="https://cf.mcp.atlassian.com/v1/register" target="_blank" rel="nofollow noopener noreferrer">https://cf.mcp.atlassian.com/v1/register</a>

When configuring the MCP server in Microsoft Copilot Studio, the connection fails during Dynamic Client Registration with the following error:

Failed to login.
GetDynamicClientRegistrationResultAsync failed.

Status Code: Unauthorized

{
  "error": "invalid_token",
  "error_description": "Missing or invalid access token"
}

I'd like to understand whether this is an expected behavior or if I'm missing any required configuration.

My questions are:

1. Is Microsoft Copilot Studio officially supported as an MCP client for the Atlassian Remote MCP Server?

2. Does the <a href="https://cf.mcp.atlassian.com/v1/register" target="_blank" rel="nofollow noopener noreferrer">https://cf.mcp.atlassian.com/v1/register</a> endpoint support Dynamic Client Registration (RFC 7591) for external clients?

3. Is there any additional authentication or registration step required before calling the registration endpoint?

4. Should new integrations use /v1/mcp/auth or /v1/mcp/authv2?

5. Has anyone successfully connected Microsoft Copilot Studio (or another MCP client using OAuth/DCR) to the Atlassian Remote MCP Server?

Any guidance or working examples would be greatly appreciated.

Thanks!

Hi @Vanessa Soto Lobos 

Welcome to the community.

This seems like an issue on the MS side,as this is mentionedin other post as well.

It seems to relate to, that Microsoft Copilot Studio, can't handle that Atlassian MCP has upgraded their OpenApi specification to V3 which is not supported in Copilot Studio.
