openrouter-mcp-multimodal

Overview

This MCP server offers comprehensive multimodal capabilities through OpenRouter, connecting Claude Desktop, Cursor, Kiro, VS Code, Windsurf, or Cline to a wide range of language models. It distinguishes itself by providing both analysis and generation capabilities across multiple media types in a single package, including text processing, image analysis/generation, audio analysis/generation, and video understanding/generation. The server supports advanced features like response caching, web search, provider routing with customizable sorting, and the latest MCP 2025-06-18 specification with structured outputs and progress notifications.

FAQ

What models are supported?

The server provides access to 300+ LLMs through OpenRouter, including models from Anthropic (Claude), Google (Gemini), OpenAI (GPT), and others. You can search and filter models by name, provider, or modality using the search_models tool.

How do I configure provider routing?

You can set provider preferences using environment variables like OPENROUTER_PROVIDER_SORT (price/throughput/latency), OPENROUTER_PROVIDER_IGNORE (CSV of provider slugs to exclude), and OPENROUTER_PROVIDER_DATA_COLLECTION (allow/deny). These can also be set per request in the chat_completion tool.
