/install webmcp
功能描述
This skill should be used when browsing or automating web pages that expose tools via the WebMCP API (window.navigator.modelContext). It teaches agents how to discover, inspect, and invoke WebMCP tools on websites instead of relying on DOM scraping or UI actuation.
安全使用建议
This skill is coherent and does what it says: it tells an agent how to find and call WebMCP tools exposed by websites. The main risk is executing site-provided callbacks — those callbacks run page-side and can perform arbitrary actions within the page. Only use the skill when interacting with websites you trust for sensitive tasks, require or confirm user prompts before purchases or destructive actions, and prefer manual confirmation for anything that touches payments, personal data, or account changes.
功能分析
Type: OpenClaw Skill
Name: webmcp
Version: 1.0.0
The skill bundle is benign. It provides documentation and instructions for an AI agent to interact with the WebMCP API on web pages. The `SKILL.md` file clearly outlines how to detect, discover, and invoke tools exposed via `window.navigator.modelContext`. There is no evidence of malicious intent, prompt injection attempts, data exfiltration, unauthorized execution, or any other high-risk behaviors. The content is purely instructional and aligned with its stated purpose of enabling structured web interaction.
能力评估
Purpose & Capability
Name/description describe discovering and invoking WebMCP (window.navigator.modelContext) tools. The skill is instruction-only and requests no binaries, environment variables, installs, or config access — all consistent with a browser-integration helper.
Instruction Scope
SKILL.md focuses on detecting modelContext, listing registered tools, validating input schemas, invoking execute callbacks, and handling user confirmation. It does not instruct reading unrelated files, accessing unrelated env vars, or sending data to external endpoints. Note: the instructions explicitly invoke page-provided execute callbacks (i.e., run code that the website registers), which by design will run arbitrary page-side logic — agents should ensure user consent and trust the site when performing sensitive actions.
Install Mechanism
No install spec and no code files — instruction-only. This minimizes disk footprint and attack surface; nothing is downloaded or installed by the skill itself.
Credentials
The skill declares no required environment variables, credentials, or config paths. The SKILL.md does not reference any hidden env vars or credentials beyond expected browser/agent interfaces.
Persistence & Privilege
always is false and the skill is user-invocable; it does not request permanent presence or modify other skills or system-wide settings. Autonomous invocation is allowed (platform default) but not elevated by the skill itself.
