Tracking: JSON Schema Support in Inspector

[olaservo]

Overview

This issue tracks the various JSON Schema support gaps in the MCP Inspector. Improved JSON Schema compliance would allow the Inspector to properly render forms and handle tools with complex schemas.

Related Issues

• Structured form not rendering for complex input objects in v0.10.2 (regression from v0.9.0) #332 - Structured form not rendering for complex input objects (regression)
• add support for JSON Schema $defs and definitions #445 - Add support for JSON Schema $defs and definitions
• Support JSON Schema allOf, oneOf, etc. #496 - Support JSON Schema allOf, oneOf, etc.
• outputSchema does not fully support JSON Schema #552 - outputSchema does not fully support JSON Schema (closed, linked to Feature: Strict JSON Schema validation with actionable error messages in CLI mode #1005)

Scope

The Inspector should support:

• Complex nested objects and arrays with dynamic form generation
• JSON Schema references ($defs, definitions, $ref)
• Composition keywords (allOf, oneOf, anyOf)
• outputSchema rendering

Notes

This is a tracking issue to consolidate related JSON Schema feature requests. Implementation may be addressed as part of the V2 Inspector rewrite.
