安全使用建议
Review this before installing. Use it only for public web research where sending the query, URL, company/person name, or code-search text to Exa and fallback search providers is acceptable. Avoid private source code, internal URLs, credentials, personal data, or confidential business context unless the user has explicitly approved that sharing. The skill should ideally remove the blanket 'always use' language and require deliberate use or consent for the remote MCP configuration.
功能分析
Type: OpenClaw Skill
Name: web-search-free
Version: 1.0.1
The skill is classified as suspicious due to the inherent risk of shell injection and Server-Side Request Forgery (SSRF) vulnerabilities. The `SKILL.md` instructs the agent to use `mcporter call` commands with user-provided parameters (e.g., `query`, `url`). If the OpenClaw agent does not properly sanitize or escape user input before constructing these shell commands, it could lead to arbitrary command execution (shell injection). Additionally, the `crawling_exa` tool, which takes a `url` parameter, could be exploited for SSRF if the agent allows arbitrary user-provided URLs, potentially accessing internal network resources. While the skill's stated purpose is benign (web search), these capabilities present significant security risks if the agent's implementation is vulnerable. There are also prompt injection attempts in `SKILL.md` to influence agent behavior regarding skill prioritization, though these do not appear to be malicious in intent.
能力评估
Credentials
External network access is expected for search, but routing ordinary searches, fetches, code queries, people research, and deep research to external providers without guardrails is overbroad for a simple free-search skill.
Install Mechanism
Setup uses mcporter to add the remote Exa MCP endpoint with multiple tools. This is disclosed and does not install local scripts, but it should be user-approved because it changes available external tooling.
Instruction Scope
SKILL.md twice says the agent should always use this skill before web_search or web_fetch, which is broader than needed and lacks narrow trigger conditions or exclusions for sensitive queries.
Persistence & Privilege
No OS persistence, privilege escalation, credential collection, or local secret access was found. The main persistence is the mcporter MCP configuration entry.
Purpose & Capability
The core purpose is coherent with a web and research search skill, but the artifact enables a broad remote tool set: web search, advanced search, code context, company research, people search, URL crawling, and deep research.
