## What is this?

**OpenRouter MCP Multimodal** is a production-grade [Model Context Protocol (MCP)](https://modelcontextprotocol.io) server — listed on the [official MCP Registry](https://registry.modelcontextprotocol.io/servers/io.github.stabgan/openrouter-multimodal) as `io.github.stabgan/openrouter-multimodal`. It connects AI coding agents ([Cursor](https://cursor.com), [Claude Desktop](https://claude.ai/download), [VS Code](https://code.visualstudio.com), [Windsurf](https://codeium.com/windsurf), [Cline](https://github.com/cline/cline), and others) to [OpenRouter](https://openrouter.ai)'s unified LLM API over stdio.

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

| Capability  | Tools                                                                                   | Highlights                                                                                                   |
| :---------- | :-------------------------------------------------------------------------------------- | :----------------------------------------------------------------------------------------------------------- |
| **Chat**    | `chat_completion`                                                                       | 300+ models, `:nitro` / `:exacto` suffixes, provider routing, web search, response caching, reasoning tokens |
| **Vision**  | `analyze_image`, `generate_image`                                                       | OCR, captioning, VQA, image generation with reference inputs                                                 |
| **Audio**   | `analyze_audio`, `generate_audio`                                                       | Transcription, speech/music generation                                                                       |
| **Video**   | `analyze_video`, `generate_video`, `generate_video_from_image`, `get_video_status`      | Clip understanding, Veo / Sora / Seedance / Wan generation with progress notifications                       |
| **Catalog** | `search_models`, `get_model_info`, `validate_model`, `rerank_documents`, `health_check` | Model discovery, validation, reranking, ops health                                                           |

**Production hardening:** input/output path sandboxes (including analyze\_\* local files as of v4.5.2), SSRF guards, structured errors with `_meta.code`, MCP 2025-06-18 structured outputs, async video progress notifications, and **650+** automated tests (unit, mock, regression, and live integration).

## Quick start

**1. Get an API key** (free tier works) → [openrouter.ai/keys](https://openrouter.ai/keys)

**2. Run the server**

```bash
export OPENROUTER_API_KEY=sk-or-v1-...
npx -y @stabgan/openrouter-mcp-multimodal
```

**3. Add to your MCP client** (Cursor, Claude Desktop, VS Code, etc.) — see [Install](#install) below.

> **No credits required to start.** Free models such as `google/gemma-4-26b-a4b-it:free` work for chat and vision. Video/audio generation typically needs credits.

## Install

MCP servers are distributed through several packaging models. **This server is implemented in Node.js/TypeScript**; the table below maps each ecosystem method to how you run it here.

> **uvx vs npx:** In the MCP ecosystem, **`npx` runs npm (Node) packages** and **`uvx` runs PyPI (Python) packages**. Because this server is Node-based, `uvx` uses a thin [Python launcher](./python/) that execs `npx -y @stabgan/openrouter-mcp-multimodal` — you still need Node installed.

### Manual config

<details open>
<summary>npx (recommended)</summary>

```bash
export OPENROUTER_API_KEY=sk-or-v1-...
npx -y @stabgan/openrouter-mcp-multimodal
```

```json
{
  "mcpServers": {
    "openrouter": {
      "command": "npx",
      "args": ["-y", "@stabgan/openrouter-mcp-multimodal"],
      "env": {
        "OPENROUTER_API_KEY": "sk-or-v1-..."
      }
    }
  }
}
```

Pin a release: `"args": ["-y", "@stabgan/openrouter-mcp-multimodal@4.5.3"]`

</details>

<details>
<summary>uvx / pipx (Python launcher)</summary>

Install [uv](https://docs.astral.sh/uv/getting-started/installation/) (includes `uvx`), ensure **Node.js 20+** is also on your `PATH`, then:

```bash
export OPENROUTER_API_KEY=sk-or-v1-...
uvx mcp-server-openrouter-multimodal
# pin npm version: OPENROUTER_MCP_NPM_VERSION=4.5.3 uvx mcp-server-openrouter-multimodal
```

```json
{
  "mcpServers": {
    "openrouter": {
      "command": "uvx",
      "args": ["mcp-server-openrouter-multimodal"],
      "env": {
        "OPENROUTER_API_KEY": "sk-or-v1-..."
      }
    }
  }
}
```

**pipx equivalent:** `pipx run mcp-server-openrouter-multimodal`

Optional: `OPENROUTER_MCP_NPM_VERSION=4.5.3` pins the underlying npm package.

</details>

<details>
<summary>npm global</summary>

```bash
npm install -g @stabgan/openrouter-mcp-multimodal
```

```json

  "mcpServers": {
    "openrouter": {
      "command": "openrouter-multimodal",
      "env": { "OPENROUTER_API_KEY": "sk-or-v1-..." }
    }
  }
}
```

</details>

<details>
<summary>node (local clone)</summary>

```bash
git clone https://github.com/stabgan/openrouter-mcp-multimodal.git
cd openrouter-mcp-multimodal
npm ci && npm run build
```

```json
{
  "mcpServers": {
    "openrouter": {
      "command": "node",
      "args": ["/absolute/path/to/openrouter-mcp-multimodal/dist/index.js"],
      "env": { "OPENROUTER_API_KEY": "sk-or-v1-..." }
    }
  }
}
```

</details>

<details>
<summary>Docker</summary>

```bash
docker run --rm -i -e OPENROUTER_API_KEY=sk-or-v1-... stabgan/openrouter-mcp-multimodal:latest
```

```json
{
  "mcpServers": {
    "openrouter": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e",
        "OPENROUTER_API_KEY=sk-or-v1-...",
        "stabgan/openrouter-mcp-multimodal:latest"
      ]
    }
  }
}
```

Use `-i` (interactive stdio). Avoid `-t` (TTY corrupts MCP framing on some hosts).

```

Set `OPENROUTER_API_KEY` in your shell or client env before starting Claude Code.

</details>

<details>
<summary>MCP Inspector</summary>

Debug tools/list and tool calls against a live OpenRouter key:

```bash
export OPENROUTER_API_KEY=sk-or-v1-...
npx -y @modelcontextprotocol/inspector npx -y @stabgan/openrouter-mcp-multimodal
```

</details>

<details>
<summary>Windows npx</summary>

When Claude Desktop or Cursor cannot find `npx` (GUI apps often miss shell `PATH`), wrap with `cmd`:

```json
{
  "mcpServers": {
    "openrouter": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "@stabgan/openrouter-mcp-multimodal"],
      "env": { "OPENROUTER_API_KEY": "sk-or-v1-..." }
    }
  }
}
```

If still failing, use the full path from `where npx` as the command.

| Model search / validate / rerank     |     ✅      |           ❌            |
| Path sandbox + SSRF protection       |     ✅      |          rare           |
| MCP 2025 structured outputs          |     ✅      |          rare           |
| Async video + progress notifications |     ✅      |           ❌            |

## Tools

14 MCP tools. Each description includes **Use when**, **Good/Bad examples**, **Fails when**, and **Works with** so agents pick the right tool and recover from errors.

Errors use a closed `_meta.code` taxonomy: `INVALID_INPUT` · `UNSAFE_PATH` · `UPSTREAM_*` · `MODEL_NOT_FOUND` · `JOB_STILL_RUNNING` · and more.

## Examples

### Chat (free model)

```json
{
  "tool": "chat_completion",
  "arguments": {
    "model": "google/gemma-4-26b-a4b-it:free",
    "messages": [{ "role": "user", "content": "Summarize MCP in one sentence." }]
  }
}
```

### Analyze an image

```json
{
  "tool": "analyze_image",
  "arguments": {
    "image_path": "diagram.png",
    "question": "List every label in this diagram."
  }
}
```

> Use `image_path` and `question` — not `image` / `prompt`.

### Search models (vision + free)

```json
{
  "tool": "search_models",
  "arguments": {
    "query": "gemma",
    "capabilities": { "vision": true },
    "limit": 10,
    "offset": 0
  }
}
```

### Generate video (async)

```json
{
  "tool": "generate_video",
  "arguments": {
    "model": "google/veo-3.1",
    "prompt": "Ocean waves at sunrise, cinematic drone shot",
    "duration": 4,
    "save_path": "river.mp4"
  }
}
```

If the job is still running when `max_wait_ms` elapses, the response succeeds with `_meta.code: JOB_STILL_RUNNING` and a `video_id` — call `get_video_status` to resume. **This is not an error.**

More examples: [docs/plans/tool-description-improvement.md](./docs/plans/tool-description-improvement.md)

## Security

- **Input path sandbox** — `analyze_*` and reference images must stay inside `OPENROUTER_INPUT_DIR`
- **Output path sandbox** — `save_path` must stay inside `OPENROUTER_OUTPUT_DIR`
- **SSRF protection** — private/reserved IPs blocked on URL fetches
- **Untrusted content** — analyze outputs tagged `_meta.content_is_untrusted: true`

Override sandboxes only with `OPENROUTER_ALLOW_UNSAFE_PATHS=1` (discouraged).

## Configuration

<details>
<summary>Environment variables</summary>

| Variable                       | Required | Default                               | Description                          |
| :----------------------------- | :------: | :------------------------------------ | :----------------------------------- |
| `OPENROUTER_API_KEY`           | **Yes**  | —                                     | OpenRouter API key                   |
| `OPENROUTER_DEFAULT_MODEL`     |    No    | `nvidia/nemotron-nano-12b-v2-vl:free` | Default when tools omit `model`      |
| `OPENROUTER_INTEGRATION_MODEL` |    No    | `google/gemma-4-26b-a4b-it:free`      | Model used by live integration tests |
| `OPENROUTER_OUTPUT_DIR`        |    No    | `cwd`                                 | Sandbox root for `save_path`         |
| `OPENROUTER_INPUT_DIR`         |    No    | —                                     | Sandbox root for local input files   |
| `OPENROUTER_LOG_LEVEL`         |    No    | `info`                                | `error` / `warn` / `info` / `debug`  |

See [`.env.example`](./.env.example) for the full list (provider routing, image/audio/video limits, caching, video polling).

</details>

## Development

```bash
git clone https://github.com/stabgan/openrouter-mcp-multimodal.git
cd openrouter-mcp-multimodal
npm install
cp .env.example .env   # add OPENROUTER_API_KEY
npm run build
```

### Testing

**Free models for CI / zero-credit accounts:** integration tests default to `google/gemma-4-26b-a4b-it:free` (override with `OPENROUTER_INTEGRATION_MODEL`). GitHub Actions requires the `OPENROUTER_API_KEY` repository secret.

Mock tests live under `src/__tests__/mock/` and cover handlers, path sandboxes, SSRF blocks, model-cache pagination, tool descriptions, and structured outputs — **330+** additional cases beyond the core suite.

```bash
npm run lint
npm run format:check
```

## FAQ

### Do I need paid OpenRouter credits?

No, to get started. Free models work for chat and vision. Audio/video **generation** usually requires credits; analysis may return `402` on some models — the server surfaces that as a structured error.

### Which MCP clients are supported?

Any MCP-compatible client over stdio: Cursor, Claude Desktop, VS Code Copilot, Windsurf, Cline, Kiro, and custom agents.

### How is this different from calling OpenRouter directly?

This server adds MCP tool schemas, security sandboxes, error taxonomy, model caching, async video polling with progress notifications, and agent-oriented tool descriptions — so LLMs invoke the right capability without custom HTTP glue.

### Where is the security advisory for path traversal?

Fixed in 4.5.2+ — see [GHSA-3q7p-736f-x44v](https://github.com/stabgan/openrouter-mcp-multimodal/security/advisories/GHSA-3q7p-736f-x44v) and `docs/solutions/security-issues/`.

## Compatibility

Works with any MCP client. Protocol: **MCP 2025-06-18**. Node **≥ 20** (Docker image uses Node 22).
