Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

Click the MCP Servers icon in the Cline sidebar, then "Edit Configuration".

Same shape as Claude Desktop. Restart Windsurf to pick up changes.

Continue uses an array of server objects rather than a map.

        ]
      }
    }
  }
}

Add to context_servers. Zed hot-reloads on save.

claude mcp add skill-arkts-syntax-assistant-skill -- git clone https://github.com/SummerKaze/skill-arkts-syntax-assistant ~/.claude/skills/skill-arkts-syntax-assistant

One-liner. Verify with claude mcp list. Remove with claude mcp remove.

Use Cases

Real-world ways to use skill-arkts-syntax-assistant

Migrate a TypeScript module to ArkTS without fighting the compiler

👤 Devs porting existing TS code to OpenHarmony ⏱ ~45 min intermediate

When to use: You pasted TS into an ArkTS file and the compiler erupted.

Prerequisites

Skill cloned — git clone https://github.com/SummerKaze/skill-arkts-syntax-assistant ~/.claude/skills/skill-arkts-syntax-assistant

Flow

Paste the errors

Use skill-arkts-syntax-assistant — here's the TS file and the ArkTS compile errors. What's incompatible?✓ Copied

→ Errors explained with ArkTS's stricter rules, not generic TS advice
Get a compliant rewrite

Rewrite the file to be ArkTS-valid while preserving behavior.✓ Copied

→ Rewrite with typed declarations and no dynamic object mutations

Outcome: A clean ArkTS port with a note on why each change was needed.

Pitfalls

Dynamic property access patterns are everywhere in the original — Skill will refactor to typed interfaces — accept the added verbosity

Combine with: filesystem

Diagnose a specific ArkTS compilation error

👤 HarmonyOS devs stuck on a specific error ⏱ ~10 min beginner

When to use: Compiler message is cryptic and the docs don't explain.

Flow

Share error + code

skill-arkts-syntax-assistant — error: <paste>. Code: <paste>.✓ Copied

→ Root cause explained in ArkTS terms + correct pattern

Outcome: A fix plus understanding of why the rule exists.

Review a hot loop for ArkTS-specific performance issues

👤 HarmonyOS app developers tuning performance ⏱ ~20 min intermediate

When to use: Component is janky; you suspect allocation or typing pitfalls.

Flow

Show the code

skill-arkts-syntax-assistant — perf review this loop. Memory and allocation patterns.✓ Copied

→ Specific allocations flagged + array/object alternatives

Outcome: A measurably faster version or a clear 'this is already fine' verdict.

Combinations

Pair with other MCPs for X10 leverage

skill-arkts-syntax-assistant-skill + filesystem

Batch-migrate a whole directory of TS files to ArkTS

For every .ts file under src/utils, apply the ArkTS migration and save as .ets.✓ Copied

skill-arkts-syntax-assistant-skill + github

Open a PR with migration diffs chunked by file

After migration, open a PR with one commit per migrated file.✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call
migrate_ts_file	TS file path + compile errors	Porting TS code
diagnose_error	error text + code snippet	Stuck on a specific compiler error
perf_review	code + suspect area	Tuning HarmonyOS component perf

Cost & Limits

What this costs to run

API quota: None
Tokens per call: Moderate — pattern examples loaded when needed
Monetary: Free — skills are local files
Tip: Migrate file-by-file rather than whole-repo to keep context manageable.

Security

Permissions, secrets, blast radius

Credential storage: No credentials — pure prompts

Data egress: None

Troubleshooting

Common errors and fixes

Skill not invoked — Claude applies generic TS fixes that fail in ArkTS

Say 'ArkTS' explicitly; 'TypeScript' alone won't activate this skill.

Verify: ls ~/.claude/skills/skill-arkts-syntax-assistant/SKILL.md

SKILL.md frontmatter wrong

Re-clone; description drives auto-activation.

Verify: head ~/.claude/skills/skill-arkts-syntax-assistant/SKILL.md

Wrong trigger keywords — compile error not resolved

Include the exact compiler message in the prompt, not a paraphrase.

Alternatives

skill-arkts-syntax-assistant vs others

Alternative	When to use it instead	Tradeoff
Vanilla TypeScript skills	You're not targeting HarmonyOS	Misses ArkTS's stricter rules
OpenHarmony official docs	You want authoritative reference material, not a chat interface	No interactive diagnosis
