How to install io.github.lozit/mcp-freestyle

Copy-paste configuration for popular MCP clients.

transport: stdio

Config generated by PluginBench — verify against the source before use.

Environment / auth

LIBRELINKUP_EMAIL
required
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_PASSWORD
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_VERSION
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_PRODUCT
Client product identifier sent as the `product` header.
LIBRELINKUP_BASE_URL
Entry point for authentication. The regional host is discovered at login and is never configured here.
