Add toolset property to telemetry payloads in addon-mcp

[Copilot]

Tool call telemetry payloads now include a toolset property identifying whether the tool belongs to the dev or docs toolset.

Changes

• Dev tools: Added toolset: 'dev' to telemetry payloads in:

  • get-story-urls tool
  • get-ui-building-instructions tool

• Docs tools: Added toolset: 'docs' to telemetry payloads in:

  • onListAllComponents handler
  • onGetComponentDocumentation handler

• Updated test expectations to verify the toolset property is present

Example

await collectTelemetry({
  event: 'tool:getStoryUrls',
  server,
  toolset: 'dev',  // New property
  inputStoryCount: input.stories.length,
  outputStoryCount: foundStoryCount,
});

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/storybookjs/mcp/actions/runs/19445952513/jobs
  • Triggering command: node /home/REDACTED/work/mcp/mcp/packages/addon-mcp/node_modules/.bin/../tsdown/dist/run.mjs --config ../../tsdown.config.ts (http block)
• o26192.ingest.us.sentry.io
  • Triggering command: node /home/REDACTED/work/mcp/mcp/packages/mcp/node_modules/.bin/../tsdown/dist/run.mjs (dns block)
  • Triggering command: node /home/REDACTED/work/mcp/mcp/packages/addon-mcp/node_modules/.bin/../tsdown/dist/run.mjs --config ../../tsdown.config.ts (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

updat the telemetry payloads in addon-mcp. all tool calls should also include which toolset they are part of, by having a { toolset: 'docs' | 'dev' } property in the payloads.

Key Changes:

• Added toolset: 'dev' to telemetry calls in dev tools (get-story-urls, get-ui-building-instructions)
• Added toolset: 'docs' to telemetry calls in docs tools (onListAllComponents, onGetComponentDocumentation handlers)
• Updated test expectations to verify the toolset property is included
