Scan MCP configuration and protocol examples for legacy or deprecated patterns that should be reviewed when targeting MCP 2026-07-28.
Roots, Sampling and Logging are deprecated as of 2026-07-28. The old initialize session lifecycle and legacy HTTP+SSE transport are also legacy patterns for modern implementations.
Detect deprecated MCP roots, sampling, logging, legacy HTTP+SSE, old initialize sessions and older task patterns.
Use MCP Deprecated Feature 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.
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.
