Surface a per-tenant Langfuse connection section (enabled, base URL, public key, secret key) in the admin config UI. It saves through the existing /api/admin/config field API. The pinned librechat-data-provider (0.8.509) predates the langfuse config group, so a forward-compat shim extends configSchema locally until a data-provider version defining langfuse is published and pinned, mirroring the READ_AUDIT_LOG capability shim. The shim no-ops once upstream ships it.
Custom section renderer for the Langfuse config: enable toggle, host, public key, a masked (PasswordInput) secret that is write-only and only sent on change, the configured-key fingerprint returned by the backend, and a Test connection action. Adds an admin-gated testLangfuseConnectionFn that validates credentials against the Langfuse public projects endpoint.
Inject the langfuse section as a SchemaField instead of extending the pinned data-provider schema, which mixed zod v4 (app) with v3 (data-provider) and left the section unintrospected so it fell back to the generic renderer. Read saved values from parentValue (the base config slice) rather than getValue leaf paths, which only resolve edited/scope values, so a configured connection repopulates on reload with the secret redacted and its fingerprint shown.

Depends on danny-avila/LibreChat#14107
The LibreChat PR provides the dedicated tenant Langfuse connection API and encrypted secret storage. Until a data-provider release defines the
langfuseschema group, this PR includes a forward-compatible schema shim that self-disables once the dependency is updated.Summary
Adds a tenant Langfuse export section to Configuration -> Features, gated by LibreChat's fanout capability.
