MCP Router: schema.maxSchemaBytes

schema.maxSchemaBytes limits the serialized size of each configured input or output schema.

• Type: Positive integer, in bytes
• Default: 1048576 (1 MiB)

The gateway serializes and preflights each schema independently while building the tool catalog. Exceeding the limit rejects configuration before traffic is accepted. This is a schema-compilation budget, not the tool-call request or response budget.
