What is the Openrouter MCP Multimodal MCP server?

MCP server for OpenRouter with text chat, image analysis + generation, audio analysis + generation, video analysis, and video generation (Veo 3.1 / Sora 2 Pro / Seedance / Wan). Exposed over MCP by the openrouter mcp multimodal mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

One install · 14 tools · 300+ OpenRouter models · text, vision, audio & video — analysis and generation.

Unlike text-only MCP servers, one install covers the full multimodal surface:

Its toolset

Everything the assistant can do here goes through one of these:

  • chat_completion — Text chat, web search, provider routing, caching, reasoning
  • analyze_image — Vision — local path, URL, or data URL + question
  • analyze_audio — Transcribe / analyze audio files
  • analyze_video — Describe / Q&A over video files
  • generate_image — Text-to-image with optional reference images
  • generate_audio — Text-to-speech / music
  • generate_video — Text-to-video (async, resumable)
  • generate_video_from_image — Image-to-video (narrower schema)
  • get_video_status — Poll / resume video jobs
  • search_models — Paginated model catalog search
  • get_model_info — Pricing, context, modalities
  • validate_model — Cheap model ID existence check

Adding it to your client

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Configuration

You will need 2 environment variables: OPENROUTER_API_KEY, UNSAFE_PATH. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

When to reach for it

Among the AI and media services options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Openrouter MCP Multimodal's toolset — chat_completion, analyze_image, analyze_audio and 11 more — is a fair guide to whether it matches your workflow. It is maintained by stabgan; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Openrouter MCP Multimodal's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Openrouter MCP Multimodal.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the openrouter mcp multimodal mcp server does with a few real requests.

Frequently asked questions

It connects Openrouter MCP Multimodal to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (chat_completion, analyze_image, analyze_audio, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Openrouter MCP Multimodal directly.
