Check MCP list request cursors and response nextCursor values without assuming cursor internals.
MCP pagination cursors should be treated as opaque values. This utility checks basic cursor presence and type without making assumptions about server-specific cursor encoding.
Inspect MCP pagination cursor and nextCursor values for common request and response mistakes.
Use MCP Pagination Cursor 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.
This validator is useful before configuration is committed, shared with another client or moved into production. Structural validation catches many integration problems early, but runtime behavior should still be tested with the exact client and server implementation you use.
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.
