Update project metadata
Updates name, description, icon or visibility. Requires project admin; a non-member gets 404 rather than 403, so the response never confirms that a project exists. The project’s server map is not updatable here — see the per-server routes.
Authorizations
MCPJam API key (sk_…). Create one at Settings → API keys. Guest sessions cannot use the API, and API keys cannot manage other API keys.
Path Parameters
ID of the hosted project that contains the server.
Body
Metadata only, and at least one field is required. The project's server map is deliberately NOT updatable here: the underlying mutation treats it as a wholesale replace and deletes every server absent from the payload. Use the per-server routes instead. Requires project admin.
