Shopify /Shopify-AI-Toolkit

Shopify Dev MCP - AI Agent Plugin

Connect your AI tools to the Shopify platform.

The Toolkit gives your agent access to Shopify’s documentation, API schemas, and code validation for building apps, and store management through the CLI’s store execute capabilities. For more info, see the docs (opens in a new tab).

Telemetry

The skill scripts (scripts/search_docs.mjs, scripts/validate.mjs, scripts/log_skill_use.mjs) send a usage event to https://shopify.dev/mcp/usage on each invocation. The payload includes:

• tool name, skill name and version
• model name, client name, and client version (when supplied as flags)
• the search query text and search response or error text (for search_docs.mjs)
• the validation result, the validated code when present, and validator-specific context such as API name, extension target, filename, file type, theme path, and file list (for validate.mjs)
• artifact ID and revision number (when supplied)
• the user’s most recent message verbatim (truncated to 2000 chars), when the agent passes it base64-encoded via --user-prompt-base64 to validate.mjs (for skills with validation) or log_skill_use.mjs (for skills without). Encoding the prompt keeps untrusted message text out of shell syntax. Exactly one designated capture point per skill — search_docs.mjs does not carry user_prompt.
• the agent’s sessionId and toolUseId (when supplied via --session-id / --tool-use-id) so analytics can join script events with the hook’s skill_invocation event for the same activation.

The plugin also registers a PostToolUse hook (hooks/track-telemetry.sh, .ps1) on Claude Code, Cursor, and GitHub Copilot. It emits a skill_invocation event to the same endpoint whenever the agent calls the host Skill tool with a Shopify AI Toolkit skill or reads a SKILL.md from a recognized install path. The payload includes:

• skill name, skill version (when recoverable from the install path)
• trigger (skill-tool or skill-md-read)
• detected client (claude-code / cursor / copilot-cli / vscode / vscode-insiders)
• hook source (plugin or skill)
• the agent’s sessionId and toolUseId (when supplied)
• on Claude Code only: the user’s most recent prompt verbatim (truncated to 2000 chars), captured out-of-band via a UserPromptSubmit hook that stashes it locally and attached here only when a skill activates. Honors OPT_OUT_INSTRUMENTATION; other hosts carry no prompt on this surface.

The same script is also injected into each generated SKILL.md as a hooks: frontmatter block, so Claude Code emits the same event when skills are installed standalone (e.g. via npx skills add Shopify/shopify-ai-toolkit) without the plugin. Events from each source are labeled with hookSource and carry sessionId + toolUseId inside the body’s parameters object, so downstream consumers can dedup on (sessionId, toolUseId) when both surfaces are installed.

The hook does not report tool inputs, file contents, generated code, or other tool arguments. On Claude Code it can additionally attach user_prompt (the most recent prompt verbatim) via the UserPromptSubmit stash, but only when a Shopify skill activates. On other hosts (Cursor, Copilot) the hook carries no prompt and user_prompt capture happens on the script surfaces only (validate.mjs for skills with validation, log_skill_use.mjs for skills without). See hooks/README.md (opens in a new tab) for full coverage details.

This is on by default. To opt out — for skill scripts, the MCP server, and the hook — set the environment variable:

OPT_OUT_INSTRUMENTATION=true

Other install methods

If your platform doesn’t support plugins, you can install agent skills or the Dev MCP server directly. For instructions, see shopify.dev/docs/apps/build/ai-toolkit (opens in a new tab).
