Several tool schemas in ToolThirdParty::getDefinitions() declared
'required' => true inside individual properties. This is not valid
JSON Schema draft 2020-12, which requires 'required' to be an array
of property names at the parent object level.
Strict validators (such as Anthropic's Claude API used by Claude
Desktop Custom Connectors and Claude Code) reject these schemas with
HTTP 400 'input_schema is invalid', causing the entire MCP connection
to fail before any tool can be called.
This patch:
- Moves 'required: true' flags from individual properties to a proper
'required: [...]' array at the parent level
- Adds the missing parent-level required array to get_thirdparty_details
(which previously had no way to mark id as required in a compliant manner)
- Fixes 5 tools in total: get_thirdparty_details, create_thirdparty,
update_thirdparty, list_thirdparty_contacts, add_thirdparty_contact
Tested with:
- Claude Desktop Custom Connectors (BETA): tools/list now succeeds
- Claude Code CLI: 32 MCP tools load without 400 errors
