> camel-ai-tool - raw JSON Schema tool input (argSchema) for nested parameters
> ----------------------------------------------------------------------------
>
> Key: CAMEL-24334
> URL: https://issues.apache.org/jira/browse/CAMEL-24334
> Project: Camel
> Issue Type: Improvement
> Components: camel-ai
> Reporter: Federico Mariani
> Assignee: Omar Atie
> Priority: Major
> Fix For: 4.22.0
>
>
> Follow-up from CAMEL-24308 (camel-mcp-server).
> The ai-tool consumer endpoint currently supports only the flat
> {{parameter.NAME=type}} syntax (with {{.description}}/{{.required}}/{{.enum}}
> refinements). Nested or complex input schemas — arrays, nested objects, oneOf
> — are a common need for MCP tools and cannot be expressed today.
> Proposed scope:
> * New optional {{argSchema}} endpoint option accepting a raw JSON Schema
> object (inline string and/or {{resource:}} reference), mutually exclusive
> with the flat {{parameter.*}} syntax.
> * {{AiToolParameterHelper}} keeps generating the schema for the flat syntax;
> with {{argSchema}} the provided schema is used as-is for
> {{AiToolSpec.getParametersJsonSchema()}}.
> * *Security-critical*: {{AiToolExecutor}}'s argument allowlist currently
> derives accepted argument names from {{parameterDefs}}. With a raw schema,
> the allowlist MUST be derived from the schema's top-level {{properties}} —
> otherwise every argument is dropped (or worse, the filter is bypassed). This
> is the same bug class as CAMEL-24241; the required-parameter validation needs
> the same treatment.
> * Engines consuming the structured {{parameters()}} map (quarkus ToolManager
> {{addArgument}}) need the schema-based path: quarkiverse
> {{ToolDefinition.setInputSchema(Object)}} covers it; the MCP Java SDK and
> Spring AI engines already consume the JSON Schema string directly.
> * The langchain4j-agent adapter builds native schema objects from
> {{ParameterDef}} — it needs a raw-schema mapping too ({{JsonObjectSchema}}
> from JSON).
