Add Happy Horse plugin

[acedatacloud-dev]

Summary

Add a separately searchable Happy Horse third-party Cursor plugin. It reuses the existing Ace Data Cloud hosted happyhorse MCP, a focused Agent skill, and the exact service logo from the Ace Data Cloud HappyHorse integration. The English and Chinese guides cover installation, service API key, permissions, one first-run prompt, task retrieval where applicable, result inspection, Credits, and troubleshooting.

Standalone source is reviewable at AceDataCloud/HappyHorseCursor#1 and its exact commit AceDataCloud/HappyHorseCursor@1f9f589. This is a tool plugin, not a Cursor chat-model provider.

Validation

• Official node scripts/validate-plugins.mjs: passed with this marketplace entry.

• git diff --check: passed. Logo SHA-256: 58c5821d63219093ca86d5780231612218c472d66f8a66a59131a873fc736d0f.

• Authenticated hosted MCP tools/list exposed happyhorse_generate_video and happyhorse_get_task; its live schema includes the first-run parameters. This is a read-only tool/schema check, not a claim of a new paid generation or a Cursor UI install.

• On 2026-10-12, an authenticated read-only task query against the hosted MCP returned a completed historical result and an HTTPS media URL. No new paid generation was submitted. This is direct MCP validation, not a Cursor Agent UI call or Marketplace installation.

Publication state

This PR is a formal submission. Review, merge, Marketplace listing and search, user installation, and a Cursor Agent call remain separate gates. Cursor 3.24.12 is signed in; this plugin's own UI installation and Agent call have not yet been verified. No credential is committed.

Note

Low Risk
Additive marketplace and third-party plugin packaging only; no core app changes, with credentials supplied by the user at configure time.

Overview
Adds a new Happy Horse third-party Cursor plugin so users can generate videos and fetch completed clips via the Ace Data Cloud hosted MCP.

The change registers happy-horse in .cursor-plugin/marketplace.json and the root plugin table, and introduces third_party/happy-horse/ with manifest (ACEDATACLOUD_API_TOKEN), HTTP mcp.json pointing at happyhorse.mcp.acedata.cloud, an agent skill for happyhorse_generate_video / happyhorse_get_task, bilingual setup docs, and a copyable first-run prompt. It is a tool-only integration (not a chat model provider); billing and auth stay on the user’s Ace Data Cloud API key.

README attribution: the shared English/Chinese CTA links are tagged with opensource / referral / evergreen, with service/Cursor/language content values. Matching source documentation is proposed at AceDataCloud/HappyHorseCursor#2. This is a documentation-only update; source merge, official indexing, public search/install and measured activation remain separate gates.

2026-10-14 base refresh

Rebased onto current official main ce649c03ac3b75b6ae80cbd15b7e2c536caedb5a. The catalog and root README retain all 102 upstream entries and their existing content, plus this plugin's original entry. The plugin directory tree remains byte-for-byte identical (20cfd4ef02e776dc5cffb9be866d73b27783c04c), including its HTTP MCP config, API token declaration, skill, and bilingual UTM links.

Validation for the published tree de10269ed9513d245e84fc61afa43db9373eda32 at head 4982a91a2baacfa4384e827c1e73dda2e8fb2493: node scripts/validate-plugins.mjs and git diff --check pass, and merge-tree with the pinned base is clean. GitHub updateRefs was used with an atomic beforeOid lease after the ordinary Git HTTPS transport timed out. This maintains the existing submission; Marketplace approval, installation, and host acceptance remain separate stages.
