Issue connecting ServiceNow MCP Client to JIRA MCP Server

[Sangeet Mahapatra]

I am trying to establish a connection between the ServiceNow MCP client and the JIRA Cloud MCP Servicer via OAuth/API Key.

OAuth connection testing is itself successful from ServiceNow to Jira; however, when I am using that OAuth with https://mcp.atlassian.com/v1/sse, I am returning with 401..

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

Can someone help here?

Hi @Sangeet Mahapatra 

Can you tell more how looks your config? Based on error message it looks like user is using wrong token.

Regards,
Seba

Hi @Sebastian Krzewiński , I am trying to connect to the Atlassian MCP Server through ServiceNow AI Studio.
In Jira, I created OAuth, obtained client secret & client ID, and defined the Garnacular scope.

Next in ServiceNow MCP Client, I am entering URL:  https://mcp.atlassian.com/v1/sse
Client ID & Client Secret, then authorising the connection in ServiceNow MCP Client. This is creating a connection to MCP Server, OAuth records in ServiceNow.

When trying to use this inside the AI agent, it fails. Please see the screenshot below.

please do let me know in case of more question.
