## What's New:

### MCP SDK Upgraded to ^1.27.1 / mcp-proxy ^6.4.4

The `@modelcontextprotocol/sdk` dependency across the Taskade MCP server and related server packages was bumped to `^1.27.1`. The `mcp-proxy` package used by the hosted MCP server was bumped to `^6.4.4`. This pull in a patched `koa` version (host-header injection fix, alert #371) and updated `ajv`. MCP clients that connect to the hosted or workspace MCP server benefit from these security and compatibility fixes without any client-side configuration change.

### Agent Memory Available Across All LLM Models

Taskade EVE, the Genesis builder agent, now persists memory across all configured models. The agent reads and writes memory entries autonomously across conversations. This is relevant for Genesis apps that rely on long-running or multi-session agent interactions, regardless of the model selected in the app configuration.

### Context Window Credit Multiplier Introduced

AI credit consumption for large-context requests now uses a `ceil(totalTokens / 150k)` multiplier. Requests whose total token count exceeds one 150k-token window consume proportionally more credits. The effective threshold was initially shipped at 200k and adjusted to 150k shortly after. API integrators and Genesis apps making high-context agent calls (long document analysis, large knowledge bases) should account for this multiplier in credit budget planning.
