Sprites for DeepSeek Harness

Use Sprites from DeepSeek Harness: isolated, persistent Linux environments for builds, tests, experiments, and long-running services.

This repository is a Harness bundle. Its cordis.patch.yml mounts:

• @deepseek-ai/dsh-mcp-client, connected to the hosted Sprites MCP server.
• This package's index.js entry, which mounts @deepseek-ai/dsh-skill-filesystem against the packaged Sprites workflow skill.

The result is a native Cordis composition: Sprites tools appear as mcp__sprites__*, and the Sprites skill is discoverable through Harness's normal skill system.

Requirements

• Node.js 20.19 or newer. The packaged filesystem provider currently depends on Chokidar 5, whose engine floor is Node 20.19.
• DeepSeek Harness developer preview.
• Browser access for the first Sprites OAuth authorization.
• Network access for npx to run the pinned mcp-remote@0.1.38 OAuth bridge.

Harness's current Streamable HTTP MCP transport accepts static headers but does not perform MCP OAuth. This bundle therefore uses Harness's supported stdio transport and mcp-remote to complete the standard browser OAuth flow without requiring a Sprites API token.

Install

Install the GitHub checkout into the profile you use. For the built-in Web profile:

npx @deepseek-ai/dsh plugin --profile web add github:superfly/sprites-deepseek-plugin

Then start that profile:

npx @deepseek-ai/dsh --profile web

On first connection, complete the browser OAuth flow, choose the Fly.io organization, and review the connector access policy. Restart Harness once if the initial tool synchronization timed out while you were authorizing.
