Check cache metadata used by current MCP list, read and discovery results.
MCP 2026-07-28 adds cache metadata to cacheable results. ttlMs expresses freshness in milliseconds, while cacheScope distinguishes private results from results safe for shared caching.
Validate MCP 2026-07-28 cache hints including ttlMs and cacheScope values.
Use MCP Cache Hint Validator 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.
Protocol checks are especially useful when debugging interoperability between different MCP clients, servers, gateways and SDK versions. The tool analyzes the data you provide and does not initiate a live MCP exchange.
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.
