Usage Guidance
This skill appears to do what it says: create stable uxc launcher links and per-site profiles for local-mcp. Before installing or running: 1) Be aware the default launcher uses `npx -y ...` which will download and execute packages from npm each time it runs — only use it for packages/adapters you trust. 2) The script will create persistent profile directories under ~/.uxc/webmcp-profile/<site> and register commands via uxc; expect those artifacts to remain until you remove them. 3) Avoid passing untrusted adapter-module values or remote npm packages unless you trust their source. If you need higher assurance, inspect the code of @webmcp-bridge/local-mcp and any adapter packages before use.
Capability Analysis
Type: OpenClaw Skill
Name: webmcp-bridge
Version: 0.1.2
The `webmcp-bridge` skill facilitates browser automation by creating persistent shell commands and executing remote code via `npx -y @webmcp-bridge/local-mcp`. The `scripts/ensure-links.sh` script installs these persistent links (via `uxc link`) and manages browser profiles in `~/.uxc/webmcp-profile/`, which contain sensitive session data. While these high-risk capabilities (remote execution, persistence, and file system access) are plausibly needed for the stated purpose of a browser-to-MCP bridge, they represent a significant attack surface and provide a platform for potential misuse without evidence of direct malicious intent.
Capability Assessment
Purpose & Capability
The name and description match the requested artifacts: uxc links, per-site profiles under ~/.uxc/webmcp-profile/<site>, and use of @webmcp-bridge/local-mcp. Required tools (uxc, npx) and the included scripts (ensure-links.sh, validate.sh) are appropriate for creating and managing those links.
Instruction Scope
SKILL.md limits actions to creating links, inspecting bridge state, switching modes, and recovering sessions. It explicitly instructs use of uxc and npx. A noteworthy behavior: the workflow runs npx to fetch/execute @webmcp-bridge/local-mcp (and optionally adapter packages or local adapter modules), which means remote/npm code or local adapter modules will be executed as part of normal operation — this is expected for the skill but is a source of risk if untrusted adapters are used.
Install Mechanism
There is no install spec (instruction-only), which is low-risk for installation. However the default launcher uses npx -y to run an npm package, which will fetch and run code from the network at launch time. The included shell scripts are plain and do not download arbitrary archives; they rely on uxc and npx being present.
Credentials
The skill declares no required env vars and the only environment influence in scripts is optional (WEBMCP_LOCAL_MCP_COMMAND, WEBMCP_DAEMON_IDLE_TTL). It writes per-site profiles under the user's HOME, which is necessary for its stated purpose. No unrelated credentials or config paths are requested.
Persistence & Privilege
always is false. The skill's agent metadata allows implicit/autonomous invocation (policy.allow_implicit_invocation: true), and the scripts create persistent links and profile directories in the user's HOME. This is coherent with the purpose, but persistent artifacts mean actions are not ephemeral — links and profiles remain on disk and can be invoked later.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install webmcp-bridge - After installation, invoke the skill by name or use
/webmcp-bridge - Provide required inputs per the skill's parameter spec and get structured output
