Kennmarq.com for coding agents

When an app generates or edits images, video or audio with AI, AI-labelling laws ask for machine-readable marks: the EU AI Act's Article 50 from 2 August 2026 (2 December 2026 for systems already on the market), California's AI Transparency Act, and others. This kit teaches coding agents to add Kennmarq.com (https://kennmarq.com) where an app makes AI media: an invisible watermark and signed C2PA Content Credentials in one call per file, plus the visible "AI" label where a law needs one. Free up to 1,000 marks a month.

It holds:

  • skills/kennmarq/: a skill in the Agent Skills format, with a reference for each stack (Vercel AI SDK, JavaScript, Python, ComfyUI, HTTP) and each market's rules;
  • rules/kennmarq.mdc: a Cursor rule that applies when AI media is in play;
  • snippets/AGENTS.md: a standing rule for a project that marks its AI files (paste it into AGENTS.md, or into CLAUDE.md for Claude Code, which reads AGENTS.md only when there's no CLAUDE.md);
  • the MCP server at https://api.kennmarq.com/mcp: each market's rules (get_requirements), the code for each stack (get_integration) and the docs (read_doc). It needs no key.

Install

Claude Code, as a plugin (the skill and the MCP server):

/plugin marketplace add Kennmarq-com/kennmarq-agent-kit
/plugin install kennmarq@kennmarq

Any agent that reads skills (Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf and others):

npx skills add Kennmarq-com/kennmarq-agent-kit

Codex: codex plugin marketplace add Kennmarq-com/kennmarq-agent-kit. Gemini CLI: gemini extensions install https://github.com/Kennmarq-com/kennmarq-agent-kit.

The MCP server alone, in Claude Code: claude mcp add --transport http kennmarq https://api.kennmarq.com/mcp; in Cursor: Add to Cursor; anywhere else, the URL https://api.kennmarq.com/mcp (Streamable HTTP).

Cursor rule: copy rules/kennmarq.mdc into your project's .cursor/rules/.

The API key

Apps call Kennmarq.com with a key in KENNMARQ_API_KEY, on the server. Ask the user to create a free account at https://kennmarq.com/signup (no card), confirm the email and create a key in the dashboard.
