6↗ read-only tools. Your assistant picks the right one from your question, and every figure it gets back carries its primary source.

Delivery model: owned-entity (own legal entities only), hybrid (own entities plus partners) or aggregator (local partners).
published_price_only
boolean
Only providers that publish a price.
sort_by
"fee" | "coverage" | "name"
fee: cheapest published fee first (default); coverage: most countries first; name: alphabetical.

country
string
Country name, two-letter ISO code or slug. Required for an employee.
hire_type
"employee" | "contractor"
employee (through an employer of record, the default) or contractor.

Questions

MCP server FAQ

Is the BestEOR.co MCP server free?

Yes. It is free and read-only, and it needs no account or API key. Add the server URL to your AI assistant and ask.

Which AI assistants can use it?

Any client that supports remote MCP servers over Streamable HTTP, including Claude (web, desktop and Claude Code), ChatGPT with developer mode, Cursor and VS Code.

Where does the data come from, and how current is it?

From the same provider catalog and country dataset this site publishes. Provider fees were last checked against each provider's own pricing page on Nov 4, 2026, and providers that only quote on request are reported as quote-only rather than given a guessed fee. Every country figure links to the source it was taken from.

Does it keep what I ask?

No. Each request is answered and discarded: the server keeps no session and stores none of the details you send. Like any website, the host logs basic request data such as the time, path and status.

Are the answers a quote?

No. Fees are each provider's published starting price per employee per month, and cost estimates apply a country's representative employer contribution rate without caps or thresholds. Use them to budget and shortlist, then confirm current terms with the provider before you sign.
