+
+v1.74.3-stable adds support for adding MCP servers to access groups, this makes it **easier for Proxy Admins** to manage access to MCP servers across users and teams.
+
+For **developers**, this means you can now connect to multiple MCP servers by passing the access group name in the `x-mcp-servers` header.

+/>
+
+<br/>
+
+This release adds cost tracking for MCP tool calls. This is great for **Proxy Admins** giving MCP access to developers as you can now attribute MCP tool call costs to specific LiteLLM keys and teams.
+
+You can set:
+- **Uniform server cost**: Set a uniform cost for all tools from a server
+- **Individual tool cost**: Define individual costs for specific tools (e.g., search_tool costs $10, get_weather costs $5).
+- **Dynamic costs**: For use cases where you want to set costs based on the MCP's response, you can write a custom post mcp call hook to parse responses and set costs dynamically.

+
+v1.74.3-stable introduces a new OSS Model Hub for telling developers what models are available on the proxy.
+
+This is great for **Proxy Admins** as you can now tell developers what models are available on the proxy.
+
+This improves on the previous model hub by enabling:
+- The ability to show **Developers** models, even if they don't have a LiteLLM key.
+- The ability for **Proxy Admins** to select specific models to be public on the model hub.
+- Improved search and filtering capabilities:
+    - search for models by partial name (e.g. `xai grok-4`)
+    - filter by provider and feature (e.g. 'vision' models)
+    - sort by cost (e.g. cheapest vision model from OpenAI)
