Merge Risk: Medium

This update includes a medium-risk change for @modelcontextprotocol/sdk and a low-risk security update for handlebars.

@modelcontextprotocol/sdk 1.29.0 → 1.31.0 (Medium Risk)

This minor version upgrade introduces a significant behavioral change in how servers handle connections. As of version 1.31.0, a McpServer or Server object is designed to serve only one connection at a time. Similarly, a stateless Streamable HTTP transport (where sessionIdGenerator is undefined) will only handle a single request.

Action required: Applications that reuse a single server object or a stateless transport for multiple HTTP requests will fail after the second request. The code must be updated to create a new server and transport for each incoming request.

handlebars 4.7.9 → 4.7.10 (Low Risk)

This is a patch release that addresses two critical remote code execution (RCE) vulnerabilities (CVE-2026-106445, CVE-2026-106446). There are no documented breaking API changes for standard usage. The fixes target unintended use-cases related to prototype access and are not expected to impact applications following documented practices.
