Feature Request: Allow configuring multiple Azure AI Search Indexes and Endpoints (One per Agent)

[Huguetteloulou]

Problem:
Currently, LibreChat only supports connecting to a single index from a single Azure AI Search resource. There are two ways to configure this:

1. Via environment variable
   You can set AZURE_AI_SEARCH_INDEX_NAME, but it only supports one index name at a time — shared across all agents.

2. Via the UI (Tools)
   You can connect an Azure AI Search index to an agent by enabling the Azure AI Search tool in the agent’s configuration. However, this tool appears to be globally scoped — meaning the last configured index (and endpoint) overwrites previous ones, regardless of which agent it was attached to.

For example, if you set up index X from endpoint A for agent X, and then configure index Y from endpoint B for agent Y, both agents end up using index Y from endpoint B.

This makes it impossible to assign different indexes to different agents, which is essential for domain-specific search use cases.

Proposed Solution:

I’d like to request one of the following enhancements:

1. UI-Based Index Isolation:

   • When configuring Azure AI Search in the UI, make the configuration agent-specific.
   • Each agent should persist and use its own index and its own Azure Search endpoint (i.e. separate resources).

2. Backend Support for Per-Agent Search config:

   • Enable multiple sets of Azure AI Search credentials (index + endpoint + key) to be configured in the backend.
   • Either allow a mapping of agents → index/endpoint combos, or enable multiple tool instances that carry their own scoped config.

---

Why This Matters:

Many use cases involve agents acting as experts on different topics — each requiring access to a dedicated Azure AI Search index. Without index isolation, this architecture isn’t currently possible.

Thanks for all the great work on LibreChat — this feature would significantly expand its multi-agent capabilities!

  I can see us getting to that Issue at some PIT as well.
