Description
An out-of-the-box hotel search skill powered by Umy MCP.
Usage Guidance
This skill advertises strict PII filtering and 'no executable code' but includes a runnable CLI that will send parameters to external endpoints. Before installing or running it, consider: 1) Do not paste or send personal data (names, phone numbers, emails, IDs) into queries — the skill's filtering is advisory, not enforced in the bundled script. 2) Inspect the script yourself or run it in an isolated environment; it calls https://api.umy.com/v1 and will include X-API-Key (falls back to the public key). 3) Ask the publisher to clarify the MCP vs API endpoint mismatch and why SKILL.md says no executable code. 4) If you want stronger guarantees, only use a version that either contains no executables or whose code you have reviewed and that enforces PII removal client-side. 5) If you set UMY_API_KEY in your environment, be aware the script will use it; keep any custom key secret and limited in scope.
Capability Analysis
Type: OpenClaw Skill
Name: umy-hotel
Version: 1.1.0
The Umy Hotel Search skill is a legitimate tool for searching hotels via the Umy MCP API. The skill includes explicit privacy-preserving instructions in SKILL.md and search-hotels.md, directing the AI agent to strip personally identifiable information (PII) from queries before transmission. The implementation in scripts/umy_hotel_tool.mjs uses standard Node.js fetch calls to a disclosed API endpoint (api.umy.com) and contains no evidence of malicious execution, data exfiltration, or obfuscation.
Capability Assessment
Purpose & Capability
The skill claims to be an instruction-only hotel search using a public key and requiring no user config, which aligns with a hotel-search purpose — but the package actually includes an executable Node CLI (scripts/umy_hotel_tool.mjs) that performs network calls. The presence of an executable contradicts the SKILL.md statement that the skill contains no executable code. Also SKILL.md references an MCP SSE endpoint (mcp.umy.com/sse) while the script uses api.umy.com/v1, which is inconsistent.
Instruction Scope
SKILL.md instructs agents to strip PII and only send structured hotel parameters, and even states 'never forward the user's raw input directly'. However, the provided CLI will POST whatever parameters it receives (including query) to an external API with no built-in PII-filtering. The skill relies on the agent/platform to enforce filtering but includes code that will transmit input if executed or used by an agent tool integration.
Install Mechanism
There is no install spec (instruction-only), which is low-risk. However, a runnable script file is bundled (scripts/umy_hotel_tool.mjs). Because nothing is automatically installed by the registry, risk depends on whether the agent/platform executes this script or exposes it as a tool — the presence of an executable file is inconsistent with the 'no executable code' claim in SKILL.md.
Credentials
SKILL.md declares no required environment variables and advertises a built-in public API key. The script respects an optional UMY_API_KEY env var (fallback to the public key). Requesting or using the public key is proportionate to a hotel search skill, but the script will use whatever API key is present in the environment (not declared as required), which should be noted by users who might set environment credentials.
Persistence & Privilege
Skill flags are default (always:false, agent-invocable:true). It does not request persistent system privileges or modify other skills. Autonomous invocation is permitted (platform default) but not combined with an 'always' flag or broad credential requests.
How to Use
- Make sure OpenClaw is installed (local or Docker)
