Summary

Vendor facts with a date and a source attached, including the ones that change every year.

The deadline and tax-rate tools carry an effective-from date and a source URL per entry, which is the difference between something you can quote and something you have to re-check. This is the public catalog only — it never touches a customer's books; a separate authenticated server does that.

What it is

A public, read-only server carrying HelloBooks' marketing-derived catalog: plans, integrations, per-country feature availability, compliance frameworks, statutory deadlines, tax rates, competitor positioning and published articles.

What you get

list_plans and list_integrations — every plan and add-on, and the banks, payroll, shipping, tax, ecommerce and storage connectors, with country and status filters
country_support and compliance_capabilities — what is available per country, and the supported frameworks with version and certification detail
compliance_deadlines — when statutory returns and payroll filings are due, per country, with a source URL on each deadline
local_payment_methods — bank rails and wallets by country with rail speed and support level
list_tax_rates and lookup_tax_rate — statutory slabs by jurisdiction, with an effective-from date and a source, or one rate resolved by country and a free-text category
list_competitors — where HelloBooks wins and where the competitor does, with pricing notes
feature_search across everything, plus list_features, list_feature_categories and list_articles
Three resources: hellobooks://about, hellobooks://changelog and hellobooks://feature-catalog

Setup effort

One command — claude mcp add --transport http hellobooks https://agents.hellobooks.ai/mcp
