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