feat(thulp-core): add ToolDefinition::to_mcp_input_schema() — bump 0.3.2#18
Merged
Conversation
Inverse of parse_mcp_input_schema(). Converts the typed Vec<Parameter> into an MCP/OpenAI-compatible JSON Schema Value, suitable for the tools[].function.parameters field that LLM APIs expect. Round-trip stable for name, type, required, description, default, enum_values. +4 unit tests covering basic, round-trip, enum/default carry, and empty-definition cases. Also: clarify thulp-registry positioning as a metadata-only catalog (not an execution runtime). Pawan and ares keep their own executable ToolRegistry; thulp-registry is for serializable tool catalogs. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Adds
ToolDefinition::to_mcp_input_schema()tothulp-coreso callers canexpose tool definitions through MCP-compatible schemas without rebuilding
the JSON shape by hand. Bumps the crate to 0.3.2 along with the
matching
Cargo.lockupdate.This came out of the
pawan-mcpparallel client wrapper work (#20 in pawan)where pawan needed to bridge thulp tool defs into MCP input schemas at
runtime — the inline reimplementation became a copy-paste hazard, so the
helper lives upstream now.
