Merged into main (commit 576fc15) and live now:

• Plugin: https://grokbot.dev/plugins/zensched/
• Bot: https://grokbot.dev/marketplace/zensched-field-crew-scheduler/

Verified before merge — zensched.com 200, github.com/zenschedmcp/zensched 200, and the share link 200 with og:title "ZenSched by Mike".

A few maintainer edits on top of your submission (everything else is yours as submitted):

• Both entries set status: live with verified_at — those are maintainer-set fields.
• pricing_note on the plugin trimmed to the 120-character schema cap (it was 171). Meaning preserved: free tier 200 calls/day unfunded, then the $5 deposit plus meter rates.
• Template tags re-mapped to the site's tag vocabulary — scheduling, field-ops, mcp and agents aren't slugs in src/data/template-tags.json. Now business, ops, calendar, back-office, automation with primary_category: business. If you'd like a different lead tag, say the word.
• Template slug is zensched-field-crew-scheduler rather than zensched, since slugs are unique across collections and the plugin already takes zensched.

Also nice to see the safety gating in the prompt — asking before any balance-spending call is exactly right for a metered MCP server. Thanks for the thorough PR, @papacarp, and welcome, ZenSched!
