Description
Real-time cryptocurrency prices, network fee estimates, and Lightning Network statistics via L402 API. Use when agents need crypto market data, fee planning,...
Usage Guidance
Do not install blindly. Before using this skill: 1) Verify the package and author on the npm registry (package.json name is @vbotholemu/mcp-crypto-data but README references @blue-trianon) and confirm the publisher is trustworthy. 2) Confirm which environment variable the published package actually reads (NAUTDEV_BASE_URL vs L402_API_BASE_URL) and whether the default API host (https://api.nautdev.com) is acceptable. If you intend to use a different endpoint, set the correct env var expected by the code. 3) Because SKILL.md and code disagree, prefer installing and inspecting the package locally (review dist/index.js) before running npx in a production environment. 4) No secret credentials are requested by the skill, but remember that any queries (coin symbols, etc.) will be sent to the remote API — avoid sending private or sensitive data to it. 5) If you need stronger safety, ask the publisher for a source repository and signed release, or run the code in an isolated environment and/or pin a specific vetted package version.
Capability Analysis
Type: OpenClaw Skill
Name: mcp-crypto-data
Version: 1.0.0
The skill bundle provides a standard Model Context Protocol (MCP) server for retrieving cryptocurrency prices and Lightning Network statistics from a specified API (api.nautdev.com). The code in src/index.ts and dist/index.js is transparent, performs no unauthorized file or network access, and lacks any indicators of malicious intent or prompt injection.
Capability Assessment
Purpose & Capability
Name/description match the code: the included Node MCP server fetches prices, fees, and Lightning stats from an external API. That functionality reasonably explains requiring a base API URL and npx for on-demand execution. However metadata mismatches (package/author names differ across files) and a missing homepage/source reduce trust.
Instruction Scope
SKILL.md instructs setting L402_API_BASE_URL, but the actual code reads NAUTDEV_BASE_URL (and falls back to https://api.nautdev.com). This means the runtime instructions/environment declaration are incorrect and the agent may talk to an unexpected default endpoint. Otherwise the instructions do not ask the agent to read local files or other secrets.
Install Mechanism
No formal install spec is included (instruction-only), and the SKILL.md shows running the package via npx. The package files are present in the bundle (src/dist/package.json), so code will be executed if installed. Using npx will fetch the package from the registry at runtime — verify the package identity on the registry before running.
Credentials
The skill declares L402_API_BASE_URL as required, but the code uses NAUTDEV_BASE_URL or a hardcoded default. There are no credentials requested for the L402 micropayments mention (which may be expected), but the env-var mismatch and the hardcoded default API host risk accidental data flow to an endpoint the user did not intend.
Persistence & Privilege
always is false and the skill does not request persistent system-wide configuration or other skills' credentials. It runs as an MCP server process and only contacts the external API; it does not modify system files or other skills' settings.
