chutes-media-mcp

Generate image, video, music and speech through Chutes from inside any coding agent — Claude Code, Cursor, Cline, Windsurf, Codex, OpenCode, Claude Desktop — and have the generated asset saved straight into the project you're working on.

It ships as:

• an MCP server (chutes-media-mcp, stdio) — the primary, universal interface,

• a thin CLI (chutes-media) — a fallback for shells and agents without MCP support, and

• an optional Agent Skill (skill/chutes-media) documenting the describe→generate workflow (auto-loaded by Claude Code; usable as reference by any agent).

Both frontends are thin adapters over one shared, transport-agnostic core, so they behave identically.

Not officially affiliated with or endorsed by Chutes. "Chutes" belongs to its respective owners; this is an independent, open-source community tool.

Features

• 🎨 Four media kinds: image, video, music, speech — plus image editing (img2img / inpaint) when a model exposes an edit cord.

• 🔎 describe → generate workflow: the live model schema is fetched and handed to the agent; payloads are never hardcoded.

• 💾 Saves assets into your project (default ./assets/chutes/<kind>/) and returns the path.

• ✅ Validates the payload against the live schema before spending a GPU call.

• 🧾 Provenance + guardrails: writes a sidecar (model, params, schema hash) next to each asset, rejects unknown params, and verifies the returned media type matches what you asked for.

• 🔁 Automatic cold-start retry with backoff for models scaled to zero.

• 📡 Progress updates during long video/music jobs (MCP progress notifications / CLI stderr).

• 🧩 Works everywhere: MCP server or CLI, same behavior.

How it works: describe → generate

Chutes models differ wildly (FLUX vs Qwen-Image vs Wan vs LTX vs ACE-Step vs a TTS model), so payloads are never hardcoded. The flow is always:

1. list_media_models — discover a model for the kind you want.

2. describe_media_model — fetch the model's live cords and input schema.

3. generate_media — submit the payload you composed; the asset is saved into the workspace.

The server owns all the plumbing: auth, cold-start warmup + retry, blocking invocation with progress, downloading, saving, light validation, and best-effort cost reporting.

Requirements

• Node.js ≥ 20.3 for the published MCP server and CLI

• Use a supported LTS release (Node.js 22 or 24) for production. Node.js 20 compatibility is retained for the current major release, but Node.js 20 itself is end-of-life.

• Contributors using the locked quality toolchain need Node.js ^20.19.0, ≥ 22.13.0, or ≥ 24

• A Chutes API key (CHUTES_API_KEY). Create one in your Chutes account.

Install

An MCP server isn't "installed" like an app — it's registered as a command in your MCP client's config (see Use as an MCP server). Pick whichever way of providing that command suits you:

1. npx from npm — recommended (no install):

npx chutes-media-mcp        # MCP server (stdio)
npx -p chutes-media-mcp chutes-media --help   # CLI bin

2. Global install:

npm install -g chutes-media-mcp
# then `chutes-media-mcp` (server) and `chutes-media` (CLI) are on your PATH

3. Directly from GitHub (no npm needed): builds on install via the prepare script.

npx -y github:TheStreamCode/chutes-media-mcp

4. From source (for development):

git clone https://github.com/TheStreamCode/chutes-media-mcp
cd chutes-media-mcp && npm ci && npm run build
# then point your client at: node /abs/path/dist/mcp/server.js

The package ships two bins: chutes-media-mcp (the MCP server) and chutes-media (the CLI).

Upgrading from 1.x

Version 2.0 makes the safety boundaries enforceable instead of best-effort:

• Existing named assets are preserved unless overwrite / --overwrite is explicitly set.

• Input and output paths must resolve inside the current workspace; symlink and junction escapes are rejected.

• Custom management API URLs require HTTPS, except loopback URLs used for local development.

• Invocation credentials are sent only to HTTPS Chutes hosts, and asset downloads must resolve to public HTTPS destinations.

• Responses and local input assets are capped by CHUTES_MAX_ASSET_MB (512 MiB by default).

If an existing automation intentionally replaces a file, add the explicit overwrite option after confirming the target path.

Configuration

Generated assets are saved to ./assets/chutes/<kind>/ by default, relative to wherever the agent is running — so they land inside the project being worked on. Output traversal and symlink escapes are rejected. Existing files are not replaced unless overwrite is explicitly enabled.

Use as an MCP server

Claude Code:

claude mcp add chutes-media --env CHUTES_API_KEY=cpk_your_key -- npx -y chutes-media-mcp

Cursor / Cline / Windsurf / OpenCode / Claude Desktop (generic mcpServers config):

{
  "mcpServers": {
    "chutes-media": {
      "command": "npx",
      "args": ["-y", "chutes-media-mcp"],
      "env": { "CHUTES_API_KEY": "cpk_your_key" }
    }
  }
}

To run without npm, replace the args with ["-y", "github:TheStreamCode/chutes-media-mcp"].

Tools

• list_media_models — { kind?, query?, limit? } → matching models.

• describe_media_model — { model } → every cord with required fields, types, defaults, a minimal example payload, and a top-level supportsEditing. Call this before generating.

• generate_media — { model, kind, params, cord?, output_dir?, filename?, timeout_ms?, overwrite? } → runs the generation and returns { path, kind, model, cord, bytes, contentType, cost?, durationMs, schemaHash?, provenancePath? }. params is what you composed from the described schema. schemaHash pins the exact cord schema the payload was validated against; provenancePath points at the sidecar (omitted when CHUTES_PROVENANCE=false).

Each tool publishes an output schema and returns the same JSON object both as text and as MCP structuredContent, so clients can consume typed results without parsing the text representation.

Example agent workflow

"Generate a hero image of a misty mountain range and drop it into the landing page."

The agent calls describe_media_model on an image model, composes { prompt: "misty mountain range at dawn, cinematic", width: 1024, height: 1024 }, calls generate_media, gets back ./assets/chutes/image/<model>-<timestamp>.png, and references that path in index.html.

Use as a CLI

export CHUTES_API_KEY="cpk_your_key"          # PowerShell: $env:CHUTES_API_KEY = "cpk_..."

# Discover models
chutes-media list --kind image
chutes-media list --query flux

# Inspect a model's schema
chutes-media describe owner/model-slug

# Generate (inline JSON, @file, or a path to a .json file for --params)
chutes-media generate --kind image --model owner/model-slug \
  --params '{"prompt":"a red bicycle on a cobblestone street"}'

# Replacing an existing named asset must be explicit
chutes-media generate --kind image --model owner/model-slug --filename hero.jpg --overwrite \
  --params '{"prompt":"a red bicycle on a cobblestone street"}'

Progress is printed to stderr; the JSON result (including the saved path) is printed to stdout, so agents can parse it.

Image editing (img2img / inpaint)

Chutes has no platform-wide edit endpoint. Editing exists only when a model publishes an edit cord (e.g. img2img, inpaint) or is a dedicated edit model. describe_media_model reports supportsEditing and lists those cords. To use one, reference a workspace file in params (a single field like image, or an array like image_b64s) — the server reads the file and base64-encodes it:

chutes-media generate --kind image --model owner/edit-capable --cord img2img \
  --params '{"prompt":"make it snowy","image":"assets/chutes/image/scene.jpg","strength":0.6}'

When a model has no edit cord, only generation is available.

Agent Skill (optional)

The MCP server already ships instructions (the describe→generate workflow), so any client receives guidance on connect — no skill required.

For Claude Code you can additionally install the bundled Agent Skill (skill/chutes-media) for richer, auto-loaded guidance:

npx -p chutes-media-mcp chutes-media install-skill             # → ~/.claude/skills/chutes-media
npx -p chutes-media-mcp chutes-media install-skill --project   # → ./.claude/skills/chutes-media

(Or copy the folder into your skills directory manually.) Agents without skill auto-loading don't need it — the tool descriptions and server instructions already guide them.

Cost

Chutes prices by compute units. When a model exposes the cost via a response header it is returned as cost; otherwise cost is omitted. Check the Chutes pricing for per-model rates.

💡 Many public models scale to zero and may return 503 no-instances until they warm up. The server retries automatically; if a model stays cold, pick another of the same kind.

Development

See CONTRIBUTING.md for setup, the build/test commands, and the Windows #-path caveat. Quick version:

npm ci
npm run check

Security

Never commit your API key. Credential-bearing requests are limited to HTTPS Chutes hosts, remote asset URLs are screened against private-network destinations, and file access is contained to the workspace. Query strings and fragments are removed from network-error messages so signed asset URLs are not copied into logs. See SECURITY.md for details and vulnerability reporting.
