Plan an MCP 2026 migration

The 2026-07-28 revision changes the lifecycle to a stateless core, moves Tasks to an extension, adds modern routing and caching behavior, and formally deprecates several older capabilities.

What this tool helps you check

Check MCP 2025-era configuration and protocol usage for changes required when moving to MCP 2026-07-28.

Use MCP 2025 → 2026 Migration Checker as a focused pre-flight utility while building, reviewing or debugging an MCP integration. Paste the relevant configuration, protocol message, metadata, schema or value into the tool and review the returned findings before the same data reaches a production client or server.

How to interpret the result

Migration checks deliberately recognize older MCP patterns so existing deployments can be upgraded safely. A legacy term appearing in this tool does not mean that the older pattern is recommended for a new deployment.

A clean result means the input passed the rules implemented by this utility. It does not guarantee application security, protocol interoperability or correct business behavior. Test important integrations against the exact MCP client, SDK, gateway and server versions used in your deployment.
