Dometrain MCP Server

Connect your coding agent to Dometrain course content. The Dometrain MCP server lets agents like Claude Code, Codex, GitHub Copilot, and OpenCode search Dometrain video-course lessons and pull curated lesson documents — summaries, cleaned lesson notes, and the exact code shown on screen, each with a timestamped deep link into the video — so your agent implements things the way your courses teach them.

• Endpoint: https://mcp.dometrain.com/mcp (streamable HTTP)
• Auth: Dometrain account API key as a Bearer token
• Access: requires an active Dometrain Pro subscription
• Server card: https://dometrain.com/.well-known/mcp/server-card.json

1. Get an API key

1. Sign in at dometrain.com and open Account settings.
2. In MCP API keys, create a key and copy it (it is shown exactly once).
3. Export it where your agent runs:

export DOMETRAIN_API_KEY="dmt_live_..."

2. Install

Claude Code

Quickest — add the server directly:

claude mcp add --scope user --transport http dometrain https://mcp.dometrain.com/mcp \
  --header "Authorization: Bearer ${DOMETRAIN_API_KEY}"

Or install the plugin (adds the server plus a skill that teaches Claude when to consult Dometrain and how to cite lessons):

claude plugin marketplace add dometrain/mcp
claude plugin install dometrain@dometrain

Codex

Add to ~/.codex/config.toml:

[mcp_servers.dometrain]
url = "https://mcp.dometrain.com/mcp"
bearer_token_env_var = "DOMETRAIN_API_KEY"

GitHub Copilot (VS Code)

Run MCP: Open User Configuration and add to your user mcp.json:

{
  "servers": {
    "dometrain": {
      "type": "http",
      "url": "https://mcp.dometrain.com/mcp",
      "headers": {
        "Authorization": "Bearer ${env:DOMETRAIN_API_KEY}"
      }
    }
  }
}

OpenCode

Add to ~/.config/opencode/opencode.json:

{
  "mcp": {
    "dometrain": {
      "type": "remote",
      "url": "https://mcp.dometrain.com/mcp",
      "headers": {
        "Authorization": "Bearer {env:DOMETRAIN_API_KEY}"
      }
    }
  }
}

Tools

Tool	What it does
search_dometrain(query, tech?, max_results?)	Search lessons for implementation guidance; hybrid keyword + semantic ranking, so conceptual queries work well — ranked excerpts with deep links (a note flags partial-term or semantic-only matches)
search_code(query, language?, max_results?)	Search the code shown on screen in lessons; snippets with a deep link to the exact moment the code appears
get_lesson(lesson_id)	Full curated lesson document: summary, key concepts, notes, on-screen code
get_course(course_id_or_slug)	Course overview + chapter/lesson tree
list_courses(topic?)	Published courses, optionally filtered by topic
get_usage()	Your monthly request usage, limit, and reset date

Notes

• Requests are limited per calendar month per account (all your keys share the pool) with a short per-minute burst cap; get_usage shows where you stand.
• Keys can be revoked any time from account settings; treat them like passwords.
• Content covers video lessons of published courses. Hands-on exercises, quizzes, and their solutions are intentionally not exposed.

Troubleshooting

• 401 — missing/invalid/revoked key. Create a new key in account settings.
• 403 — your account has no active Dometrain Pro subscription.
• 429 — monthly limit reached (response includes the reset date) or per-minute burst cap hit (retry shortly).
