This repository holds the code for a MCP server that calls the Runway API.
Runway Api MCP server exists for a simple reason — assistants are far more useful when they can act on Runway Api directly instead of describing what you should do. This repository holds the code for a MCP server that calls the Runway API.
Once Runway Api is connected, these are the calls the assistant has available:
ratio — durationrunway_listModels — Lists available models per capability and the recommended default for eachrunway_generateVideo — Generates a video from an image and a text promptrunway_generateImage — Generates an image from a text prompt, and reference imagesrunway_upscaleVideo — Upscale a video to a higher resolutionrunway_editVideo — Edits a video, optionally provide reference imagesrunway_generateAudio — Generates spoken audio (text-to-speech) from textrunway_getTask — Gets the details of a taskrunway_cancelTask — Cancels or deletes a taskrunway_getOrg — Get organization informationYou will need 2 environment variables: RUNWAYML_API_SECRET, MCP_TOOL_TIMEOUT. 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.
Before starting, you'll need to have setup your Developer account on the Runway API, setup Billing, and also created an API Key. You'll also need Node.js setup.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Plenty of planning and project tracking servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Runway Api's toolset — ratio, runway_listModels, runway_generateVideo and 7 more — is a fair guide to whether it matches your workflow. It is maintained by runwayml; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
Issue tracking at the speed of conversation — Linear's official hosted server with OAuth and zero install.
Search and read your Drive — Docs, Sheets and files become context your assistant can actually use.
Your assistant inside the workspace — read channels, search history, post messages and tame the noise.
Metabase ships its own MCP endpoint — search your BI content, build and run queries, and save questions and dashboards without leaving the chat.
Stop letting your assistant hallucinate n8n node parameters — this server hands it the real schemas, templates and validation.
