DeepSeek's Anthropic-compatible endpoint accepts only the built-in web_search_20250305 / web_search_20260209 tools and rejects client-defined `custom` tools (MCP / Read / Bash) with HTTP 400 "unknown variant `custom`". The generic non-Claude filter in prepareClaudeRequest dropped the offending tools but also dropped the web_search_* ones DeepSeek does accept. - Add an opt-in per-provider transport quirk `claudeSupportedToolTypes`; when declared it becomes a strict allow-list for Anthropic tool `type` values - Stop stripping the `type` discriminator from surviving tools under that quirk, since DeepSeek needs it to route built-ins - Declare the quirk on the deepseek transport with the two web_search_* types - Providers without the quirk keep the previous filter and normalisation behaviour byte-for-byte; openai-format targets never reach this path
