Detailed Description

JSON Schema 2020-12 validation shared by NeoGraph's MCP server, MCP client and Harness.

MCP 2025-11-25 ("JSON Schema Usage") makes 2020-12 the default dialect of every tool schema. Supported: the core, applicator, unevaluated and validation vocabularies, boolean schemas and local $ref (JSON Pointer fragments, $anchor names, $id resources in the same document); format and the content and meta-data keywords are annotations. A schema that names another dialect in $schema, uses $dynamicRef or $recursiveRef, references another document, or has a pattern std::regex cannot compile is refused by validate_json_schema().

Definition in file json_schema.h.
