Mcp License

MCP check_npm_license: npm license triage for coding agents — call immediately before npm install, yarn add, or pnpm add.

Overview

MCP check_npm_license: npm license triage for coding agents — call immediately before npm install, yarn add, or pnpm add. Returns npm-declared license, SPDX id, and permissive-default compatible (yes | no | unknown) so the agent can proceed, swap package, or escalate. Not SBOM, not legal advice. Free taste: GET /license/check/preview (same JSON, $0), then pay GET /license/check or MCP check_npm_license for the package you will install.

Endpoint

Method	Endpoint	Price	Description

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/mcp-license \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/mcp-license \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
