Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
LIBRELINKUP_EMAILRequired | LibreLinkUp *follower* account e-mail — not the primary LibreLink account. The password is stored once via `npx mcp-freestyle-login` in the OS keychain, so it never appears in this configuration. |
LIBRELINKUP_PASSWORDOptional, secret | Overrides the OS keychain. Intended for CI and one-off runs; prefer `mcp-freestyle-login` so no credential lands in a config file. |
LIBRELINKUP_VERSIONOptional | Pinned LibreLinkUp client version sent as the `version` header. Upstream rejects stale values — set this to the current LibreLinkUp app version if requests start failing. |
LIBRELINKUP_PRODUCTOptional | Client product identifier sent as the `product` header. |
LIBRELINKUP_BASE_URLOptional | Entry point for authentication. The regional host is discovered at login and is never configured here. |
