Add Happy Horse by Ace Data Cloud 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 plugin metadata only; no core tooling changes. Users supply API tokens to a third-party hosted MCP, which is the standard third_party integration pattern.

Overview
Adds Happy Horse by Ace Data Cloud as a new third-party Cursor plugin and registers it in the root marketplace catalog and README plugin table.

The new third_party/happy-horse package wires Cursor to Ace’s hosted HTTP MCP (happyhorse.mcp.acedata.cloud) via mcp.json, with a required Configure variable ACEDATACLOUD_API_TOKEN (Bearer auth). Manifest v1.0.1 brands the integration as independent from Cursor/model vendors and includes discovery keywords, min Cursor 3.13.0, and an agent skill that documents generate-once / poll-with-happyhorse_get_task behavior.

Onboarding is mostly docs: English and Chinese READMEs, a copy-paste first-run prompt, troubleshooting, changelog/LICENSE, and SOURCES.json for tutorial image provenance (Ace console + official Cursor MCP UI references).

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.

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.

2026-10-18 native-distribution update

Updated onto current official main 101b274dd991f694e1f7024be2157e5f3adf07de. All 109 existing catalog entries and the full upstream README are preserved, including the revised Tailscale text. This service is now displayed as <service> by Ace Data Cloud, with relevant discovery keywords, version 1.0.1 and illustrated English/Chinese onboarding. Reuses masked real Ace token screenshots and original official Cursor references; Suno additionally includes an explicitly labeled official-original edit preview, not execution evidence. Matching source PR: AceDataCloud/HappyHorseCursor#2. Current Configure screenshot and real Marketplace search/install remain pending. No hosted MCP/Auth/skill/action/model/price behavior changed.

Validation at 48800e93821f0bc172577f593b298b4f234d5027: current node scripts/validate-plugins.mjs, node scripts/generate-pstack-harness-trees.mjs --check, git diff --check and merge-tree pass. Published Git commit/tree SHAs equal the locally validated objects. Every original OPEN branch update uses atomic beforeOid comparison. No duplicate submission, PR merge, deployment, paid generation or publisher agreement acceptance. Official review, live service-name search, installation and actual Cursor use remain separate gates.
