Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
When the agent uses the Atlassian MCP plugin (plugin-atlassian-atlassian / remote https://mcp.atlassian.com/v1/mcp), each successful Jira tool call is followed by a visible chat error:
MCP error -32601: Method not found
The UI shows “Ran Create Jira Issue in atlassian” (or other Atlassian tools), then immediately surfaces this error. The underlying Jira operation succeeds — issues are created/updated in Jira as expected. The error is cosmetic but very noisy (one error per tool invocation).
Steps to Reproduce
- Install and authenticate the Atlassian MCP plugin in Cursor.
- In Agent chat, ask the agent to create one or more Jira issues in a project you have write access to (e.g.
TECHSERV). - Observe the chat tool-run UI after each
createJiraIssue(or similar) call.
Expected Behavior
- Tool runs successfully.
- No error shown in chat when the server does not advertise MCP Apps / widget resources.
