# Troubleshooting & Reference

> Fixes for common MCP connection issues, plus technical details and support contacts.

## Troubleshooting

<AccordionGroup>
  <Accordion title="Authentication fails or loops">
    * Confirm you are signed in to Listen Labs in the browser that opens for consent
    * Remove and re-add the MCP server in your client to trigger a fresh OAuth flow
    * Check that your client supports remote OAuth MCP (not only local stdio servers)
  </Accordion>

  <Accordion title="&#x22;Access denied&#x22; on a study">
    Your Listen Labs user does not have access to that study's organization. Verify access in the dashboard.
  </Accordion>

  <Accordion title="Analysis tool returns nothing useful">
    `get_study_analysis` requires a completed analysis run. Check `list_studies` for `has_analysis: true`. New or in-progress studies may not have analysis yet.
  </Accordion>

  <Accordion title="Client shows &#x22;Method not allowed&#x22;">
    The server is stateless and only accepts `POST` on `/mcp`. Ensure your client uses Streamable HTTP, not SSE session polling on `GET /mcp`.
  </Accordion>

  <Accordion title="&#x22;Study is currently being updated&#x22;">
    Another edit or save is in progress. Wait a moment and try again.
  </Accordion>

  <Accordion title="&#x22;No permission to launch&#x22;">
    Your role may allow editing but not starting recruitment. Ask an admin for launch permissions.
  </Accordion>

  <Accordion title="Changes aren't visible to respondents">
    Edits on live studies stay in draft until published. Ask your assistant to publish or launch the study.
  </Accordion>
