npm license check before install — 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. Many packages: GET /license/lockfile/preview then /license/lockfile.

Convert amounts between ISO 4217 currencies using ECB daily reference rates (Frankfurter). Use for invoices, travel budgets, expense reports, and shopping comparisons when you need a verifiable rate instead of LLM arithmetic. Not live tradable FX — rates follow ECB business-day publication.

package-lock.json license batch triage — coding-agent merge gate. Pass top-level lockfile packages as name@version (max 20). Returns per-package SPDX + permissive-default compatible, rollup counts, and overall yes|no|unknown. Not a compliance SBOM. Free taste: GET /license/lockfile/preview (max 2), then pay GET /license/lockfile for the full list. Single package: GET /license/check.

English Wikipedia fact lookup: search by query or exact title, returns intro extract as plain text. For agents that need a grounded summary before deeper web search. Not a substitute for primary sources.
