Aisma MCP server and API

Edit a video you already shot by describing the change in plain words, from any AI assistant, agent or script. Remove a person or an object, change an outfit, the background or a product, swap a face from your photos, restyle the clip or add an effect. Aisma keeps the original framing and audio and delivers a private 720p or 1080p result to your Aisma Library.

• MCP server (remote, Streamable HTTP): https://api.aisma.ai/mcp

• REST API: https://api.aisma.ai/v1 (OpenAPI 3.1)

• Developer docs: https://aisma.ai/developers

• Official MCP Registry name: ai.aisma/aisma

This repository holds documentation, the registry server.json and small client examples. The server itself is hosted by Aisma; there is nothing to install or run.

What you need

• An Aisma account signed in with Google, Apple or email. Guest profiles can't connect apps or hold keys.

• Credits in that account. Edits use the same credits as the Aisma app, and the price of each edit is shown before it starts. Credits are bought in Aisma, never through the API or MCP. Pricing: https://aisma.ai/pricing

• A clip of 2–60 seconds (MP4 or MOV, up to 500 MB), or a finished video from your Aisma Library. Optionally up to 10 reference photos (JPEG, PNG or WebP).

Connect an AI assistant (MCP)

Your client opens Aisma's sign-in page on first use: OAuth 2.1 with PKCE and dynamic client registration, so there is no client ID to copy. On the consent screen you choose what the connection may do and its monthly credit limit. You can change limits or disconnect at any time in Aisma under Profile → Settings & help → Connected apps and keys (https://aisma.ai/app/api-access).

Prefer a key? Create a personal API key on the same page and send it as Authorization: Bearer aisma_live_…. Each key has its own permissions and limits, adjustable per key on that page.

Claude Code

claude mcp add --transport http aisma https://api.aisma.ai/mcp
# or with a personal API key
claude mcp add --transport http aisma https://api.aisma.ai/mcp --header "Authorization: Bearer $AISMA_API_KEY"

Cursor (~/.cursor/mcp.json or .cursor/mcp.json in a project)

{
  "mcpServers": {
    "aisma": { "url": "https://api.aisma.ai/mcp" }
  }
}

With a key, add "headers": { "Authorization": "Bearer aisma_live_…" } next to url.

VS Code (.vscode/mcp.json)

{
  "servers": {
    "aisma": { "type": "http", "url": "https://api.aisma.ai/mcp" }
  }
}

ChatGPT (custom MCP servers, where your plan and workspace allow them): open chatgpt.com/plugins, choose + → Add custom MCP server, enter https://api.aisma.ai/mcp, pick OAuth and sign in to Aisma.

Claude.ai and Claude Desktop: Settings → Connectors → Add custom connector → https://api.aisma.ai/mcp.

Other clients: any client that supports remote MCP servers over Streamable HTTP works. The server is stateless and answers protocol revisions 2025-11-25, 2025-06-18 and 2025-03-26. An unauthenticated request gets 401 with WWW-Authenticate: Bearer resource_metadata=…, which is how clients discover the sign-in.

Chat-only assistants: an honest limitation

Video files never travel inside MCP messages. create_upload returns a one-time HTTPS link and the assistant uploads the file itself with an HTTP PUT. That works in assistants that can read your files and run commands (Claude Code, Cursor, VS Code and other coding agents). A chat-only assistant (ChatGPT, Claude.ai) can't upload a new clip this way; there it can re-edit videos that are already finished in your Aisma Library (list_library → use_library_video).

Tools

Every tool has a title, read-only or destructive hints and an output schema.

Try it

• "Upload ~/Videos/wedding.mov to Aisma and remove the man in the red jacket behind the couple. Ask me before you start."

• "In product.mp4, swap the clear perfume bottle for the matte-black one in bottle.jpg."

• "Change her gray tracksuit in dance.mp4 to the red suit in photo.png."

• "Take my latest finished Aisma video and turn the corridor into a snowy pine forest at 1080p."

• "Check my Aisma edit and send me the link when it's ready."

REST API quick start

Send your key as a bearer token and a descriptive User-Agent header (for example my-app/1.0): some HTTP libraries' default agents are refused by our edge network. Bodies are JSON, ids are UUIDs.

1. POST /v1/uploads returns uploadUrl, method (PUT) and headers. PUT the file there with those headers.

2. Poll GET /v1/assets/{id} until status is ready.

3. POST /v1/quotes prices the edit. A 202 with retryAfterMs means the clip is still being checked; ask again after that delay.

4. POST /v1/jobs with an Idempotency-Key header starts the quoted edit. A retry with the same key returns the same edit.

5. Poll GET /v1/jobs/{id} (no more often than every 10 seconds) or register a webhook, then POST /v1/jobs/{id}/result for a one-hour link.

export AISMA_API_KEY=aisma_live_...

curl -s -X POST https://api.aisma.ai/v1/uploads \

  -d '{"kind":"video","contentType":"video/mp4","bytes":12345678}'
# PUT clip.mp4 to uploadUrl with the returned headers, then wait for GET /v1/assets/ASSET_ID → ready

curl -s -X POST https://api.aisma.ai/v1/quotes \
  -H "Authorization: Bearer $AISMA_API_KEY" -H "User-Agent: $UA" -H "Content-Type: application/json" \
  -d '{"sourceId":"ASSET_ID","brief":"change the background to a snowy forest","quality":"720p"}'
