Description
Check if an email has appeared in known data breaches and get detailed breach history, severity, compromised data, and remediation recommendations.
Usage Guidance
This skill looks like what it says (an external breach-check API), but the SKILL.md expects an API key while the registry metadata declares no required credential — that's an incoherence you should resolve before installing. Before using: 1) Ask the publisher to declare the required API key/env var in the skill metadata (and confirm where the key is stored and how it's protected). 2) Verify the external API domain (toolweb.in) and the publisher's identity/terms/privacy policy; confirm TLS and data-retention practices. 3) Consider privacy: the skill will send email addresses (and possibly other context) to a third party — avoid sending sensitive or production emails until you're confident in the provider. 4) If you allow autonomous invocation, be aware the agent could send user emails automatically; restrict scope or require explicit user approval for every check. 5) Test with non-sensitive example emails and confirm expected behavior and error handling before enabling in production.
Capability Analysis
Type: OpenClaw Skill Name: toolweb-breached-email-check Version: 1.0.0 The skill bundle defines a legitimate tool for checking email breach history via the ToolWeb.in API. The documentation in SKILL.md clearly outlines the tool's purpose, expected input/output, and the external endpoint (portal.toolweb.in). No malicious code, unauthorized data access, or prompt injection attempts were found.
Capability Assessment
Purpose & Capability
Name, description, and SKILL.md behavior align: it checks an email against breach databases and returns breach details. The endpoints and outputs described match the stated purpose.
Instruction Scope
Runtime instructions are limited to calling an external API to check emails and returning breach data — that is within scope. However, the SKILL.md explicitly instructs sending email addresses to portal.toolweb.in (and to pass an API key or MCP argument), which means user-supplied emails will be transmitted off-platform; SKILL.md does not include privacy/retention rules or limits on what context to include when calling the API.
Install Mechanism
Instruction-only skill with no install spec or code files — nothing is written to disk and no external installers are used.
Credentials
SKILL.md requires an API key via an X-API-Key header or 'mcp_api_key', but the registry metadata declares no required environment variables or primary credential. This mismatch is important: the skill will need credentials to function (and to be useful), but none are declared. The skill will transmit potentially sensitive email addresses to an external service, which requires explicit vetting of the credential handling and trust in the remote API provider.
Persistence & Privilege
always is false, no system config paths or persistent privileges are requested. Autonomous invocation is allowed (platform default) — note this increases the blast radius because the skill sends data externally, but the skill itself does not request unusual privilege escalation.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install toolweb-breached-email-check
  3. After installation, invoke the skill by name or use /toolweb-breached-email-check
  4. Provide required inputs per the skill's parameter spec and get structured output
