`list_models`

Pack: openrouter · Endpoint: https://gateway.pipeworx.io/openrouter/mcp

List LLMs from the OpenRouter catalog (~340 models across all major providers) with normalized $/1M-token pricing, context windows, and modality. Filter by search, free-only, minimum context, or modality (e.g. “image” for vision models). Sorted cheapest-first by completion price. Keyless.

Parameters

Name	Type	Required	Description
`search`	string	no	Case-insensitive substring match against model id, name, and description. e.g. “claude”, “gpt-4o”, “deepseek”.
`free_only`	boolean	no	If true, only return models whose prompt price is $0 (free tier).
`min_context`	number	no	Minimum context_length in tokens, e.g. 100000 or 200000.
`modality`	string	no	Substring match on architecture.modality, e.g. “image” to find vision/multimodal models, “text->text” for text-only.
`limit`	number	no	Max models to return (default 25, max 60).
