### MCP Gateway - Control Tool Access by Team, Key

<Image 
  img={require('../../img/release_notes/tool_control.png')}
  style={{width: '100%', display: 'block', margin: '2rem auto'}}
/>

<br/>

Proxy admins can now control MCP tool access by team or key. This makes it easy to grant different teams selective access to tools from the same MCP server.

For example, you can now give your Engineering team access to `list_repositories`, `create_issue`, and `search_code` tools, while Sales only gets `search_code` and `close_issue` tools. 

This makes it easier for Proxy Admins to govern MCP Tool Access.

## Performance - 70% Lower p99 Latency

<Image img={require('../../img/release_notes/1_78_0_perf.png')}  style={{ width: '800px', height: 'auto' }} />

<br/>

This release cuts p99 latency by 70% on LiteLLM AI Gateway, making it even better for low-latency use cases.

These gains come from two key enhancements:

**Reliable Sessions**

Added support for shared sessions with aiohttp. The shared_session parameter is now consistently used across all calls, enabling connection pooling.

**Faster Routing**

A new `model_name_to_deployment_indices` hash map replaces O(n) list scans in `_get_all_deployments()` with O(1) hash lookups, boosting routing performance and scalability.

As a result, performance improved across all latency percentiles:

- **Median latency:** 110 ms → **100 ms** (−9.1%)
- **p95 latency:** 440 ms → **150 ms** (−65.9%)
- **p99 latency:** 810 ms → **240 ms** (−70.4%)
- **Average latency:** 310 ms → **111.73 ms** (−64.0%)

### **Test Setup**
