EOR Scope
io.github.eorscopev0.2.0Updated Oct 6, 2026
Statutory employer cost by country, before any Employer of Record (EOR) fee.
Overview
An offline MCP server that estimates statutory employer costs for hiring in 76 countries, before any Employer of Record fee.
- What it does
- It answers what an employer pays on top of gross salary in a given country, line by line, using the same engine and data as the EOR Scope calculator. Tools include list_countries (with an optional region filter), employer_cost (country plus optional salary, currency and assumptions), and compare_countries (two to ten countries at a fixed salary). Every answer is JSON with a meta block containing the snapshot date, page and methodology URLs, disclaimer and data licence; each contribution line carries its official source and the date it was read.
- When to use it
- Use it when comparing the statutory employer burden of hiring in different countries, or when checking the individual contributions behind a country's total. It is a cost-comparison aid, not legal or tax advice, and it does not include EOR provider fees.
- Requirements
- Node 18 or later; it runs locally over stdio, typically via npx. No accounts, API keys, environment variables or headers are declared, and the data ships inside the package, so the server makes no network call.
Installation
In SourceWeft
- Open EOR Scope in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
README
eorscope-mcp
A Model Context Protocol server (stdio) that answers one question about hiring abroad, before any Employer of Record (EOR) fee: what an employer pays on top of a gross salary in a given country (statutory employer contributions, line by line, each with its official source and the date it was read).
It does not carry EOR provider fees: the providers' terms do not allow their prices to be redistributed. Compare providers on their own pricing pages.
It runs the same engine and the same data as the EOR Scope calculator: 76 countries in the snapshot of 2026-10-04. The data ships inside the package; the server makes no network call.
Cost comparison, not legal or tax advice.
Install
Node 18 or later.

Tools
Every answer is JSON and ends with a meta block: the snapshot date, the URL of the matching page on the site, the URL of the methodology page, the disclaimer and the data licence. The examples below are real outputs of the 2026-10-04 snapshot, shortened where marked …; meta is left out.
Figures come as text ("at least $156") and as numbers under values, next to a bound field. When a country's total is declared as a floor or a ceiling, the words "at least" or "at most" are part of the figure: keep them when you quote it.
list_countries
Optional region. Alphabetical order.
employer_cost
country (ISO code or name), optional salary with salary_currency (USD or local), optional assumptions, optional include_notes. Without a salary, the country's example salary is used. {"country": "India"} returns the figure printed on the India page:
compare_countries
countries (2 to 10) and salary_usd. Rows come back in the order requested, not ranked. {"countries": ["DE", "PL", "AE"], "salary_usd": 80000}:
Sources and method
- Employer contributions: the tax and social-security administrations and the legislation of each country. Each line carries its source URL and the date it was read; a line that rests on a secondary source says so in its note (
include_notes). - Exchange rates: ECB reference rates; the issuing central bank's parity for currencies pegged to the dollar; the European Commission's monthly accounting rate for the rest. The rate, its date and its source are in every answer.
- Calculation: each contribution on its own base (gross, basic wage, fixed amount or a band of gross), floored and capped as the law writes it and skipped where a salary threshold excludes it, plus the recurring statutory extras the country counts in its total. Employee-side deductions and income tax are not modelled.
The full method, its known limits and the list of sources are on the methodology page.
The numbers are an illustrative model of statutory charges. Confirm every figure with a qualified local adviser before hiring.
Development
The engine is the site's own, not a rewrite, and it is not under the MIT terms of the rest of the code (see Licence). src/vendor/ (engine and formatters), data/snapshot.json and test/fixtures/country_summary.csv are copied from the site's repository by npm run sync; do not edit them here. sync only has something to do inside that repository. In a checkout of this package alone it says so and changes nothing.
Licence
