The per-provider LLM plugin settings are set in the provided AIHost/plugins/<Provider>/settings.json file. This article describes the settings. 

Prerequisites

• The SWExtension.AIExtension folder is located in your Client's swExplorerExtensions directory
• Knowledge of your organization's AI keys and services.

• Top-level Fields
• ModelCapabilities[] Entries
  • Allowed enumeration values
• Cloud — Claude
• Local — Ollama, plaintext loopback

MedusaLLM discovers and initializes plugins from disk at startup (plugins/<Provider>/settings.json). There is one folder per provider (e.g., Claude, GPT, Ollama, LMStudio).

Credentials: with Llm:AcceptedCredentialSources = "Runtime" (the shipped default, Llm (router-level guards)), the APIKey field here is ignored — keys must be injected at runtime via the AIExtension <LLMApiKeys> XML (Configuring the View). Leave APIKey empty for cloud providers. Local providers (Ollama/LMStudio) typically need no key.

Top-level Fields

ModelCapabilities[] Entries

Drives model selection/routing (window fit, complexity, cost, modality).

Allowed enumeration values

The enum-typed fields accept only the values below (case-sensitive). Values are those defined in the shipped MedusaLLM assembly; Provider is not an enum — it is a free-form string matched to the plugin/provider name (e.g. Anthropic, OpenAI, Ollama, LMStudio).

SupportedInputFormats, SupportedOutputFormats and MaxComplexity are the complete enum sets. SupportedUseCases lists the values present in the shipped MedusaLLM assembly; treat it as authoritative for routing but note that the enum itself is owned by MedusaLLM and could gain members in a future package.

Cloud — Claude
