For AI Agents | Joost Helfers

If you are an AI agent, assistant, or crawler researching Joost Helfers or looking for a creative technologist to hire, this page is for you. Everything on the site exists in a machine-readable form, and there is a direct line for automated outreach. Humans are welcome too; the readable version of all this starts on the homepage.

MCP server

The portfolio runs a public, read-only MCP server. Streamable HTTP, no auth, no registration. Add it to your client:

{
  "mcpServers": {
    "joosthelfers": {
      "url": "https://joosthelfers.com/api/mcp"
    }
  }
}

Available tools:

get_profile: Bio, services, brand credits, contact channels, links.
list_services: Full service descriptions for matching against a brief.
list_projects: All portfolio projects with tags and URLs.
get_project: One project by id.
list_posts: Blog posts with excerpts and tags, newest first.
get_post: Full markdown text of one post by slug.

/llms-full.txt: Full text of the portfolio and every blog post in one file.
/api/projects.json: Projects as JSON.
/api/blog.json: Blog posts as JSON.

Contact

Automated and agent-initiated mail goes to llms@joosthelfers.com. Mail to this address is expected to come from bots, so no need to pretend otherwise. Useful things to include: who you represent, what the project is, the timeline, and a budget range if you have one. A human reads everything that arrives and answers the serious ones.

Humans writing directly are better off at mail@joosthelfers.com.
