/install nameserver-reverse
Description
Perform reverse lookup of gTLD domains hosted on a specified nameserver with optional filters by TLD and domain prefix length.
Usage Guidance
This skill is an integration guide for DomainKits' MCP endpoints and appears internally consistent. Before installing or applying the suggested edits: (1) confirm you trust https://mcp.domainkits.com and the github repo (https://github.com/ABTdomain/domainkits-mcp) because the instructions rely on npx (which fetches and runs packages) and an optional GitHub extension; (2) back up any client config files before editing them (the SKILL.md names paths in your Claude and Cursor configs); (3) note that no credentials are requested by the skill, but running npx or installing third-party extensions will execute remote code — only proceed if you trust the upstream projects; (4) if you want the agent to perform these edits automatically, review the exact changes it will make so it doesn't overwrite unrelated settings.
Capability Analysis
Type: OpenClaw Skill
Name: nameserver-reverse
Version: 1.0.0
The skill bundle defines two domain intelligence tools (`search_nrds`, `search_ns_reverse`) that interact with external endpoints at `https://mcp.domainkits.com`. The `Skill.md` provides clear instructions for users on how to configure clients and examples of API calls. There is no evidence of prompt injection attempts against the agent, malicious execution, data exfiltration, or persistence mechanisms. All instructions and code snippets are aligned with the stated purpose of providing domain intelligence services.
Capability Assessment
Purpose & Capability
The skill advertises MCP-based domain intelligence endpoints (NRDS and NS-reverse) and all instructions target those endpoints. One mismatch: the SKILL.md uses 'npx' and references an 'mcp-remote' client (and a Gemini GitHub extension), but the skill metadata lists no required binaries — in practice the user/agent will need node/npm (npx) or the specified client to follow the instructions.
Instruction Scope
Runtime instructions are narrowly scoped to adding MCP servers to local client configs and invoking the service (curl examples and client config snippets). They do ask the user/agent to edit local application config files (Claude and Cursor paths), which is expected for integration but should be done deliberately; there are no instructions to read unrelated system files or exfiltrate data.
Install Mechanism
There is no install spec and no code files (lowest disk-risk). The README suggests installing a Gemini extension from a GitHub repo and the use of 'npx mcp-remote' (which will pull packages on demand). These are normal but rely on fetching code from GitHub/npm at runtime — users should be aware that running npx will execute downloaded code.
Credentials
The skill declares no environment variables, no credentials, and no config-path requirements beyond client configuration files. That is proportionate to a read-only domain-intel lookup service: it does not request secrets or unrelated cloud credentials.
Persistence & Privilege
The skill does not request always:true and is not force-included. It does not attempt to modify other skills or system-wide settings; it only instructs modifying local client config files for integration, which is an appropriate level of persistence for this purpose.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install nameserver-reverse - After installation, invoke the skill by name or use
/nameserver-reverse - Provide required inputs per the skill's parameter spec and get structured output
