403 — The acting user may not use this workspace
What happened
The MCP request was refused because of who it acts as. There are two reasons:
- The key named another user in the
x-fullvision-acting-userheader, and only the workspace's own dashboard key may act on behalf of someone else. Message: "This API key cannot act on behalf of another user." - The acting user is not a member of the workspace. Message: "The acting user is not a member of this workspace."
Why it usually happens
- The key was created by someone who has since left the workspace. A key acts as the person who created it, so it stops working when they leave.
- A key other than the workspace's own dashboard key sent
x-fullvision-acting-usernaming someone else.
How to fix
- Use an API key created by a current member of the workspace.
- Do not send the
x-fullvision-acting-userheader.
