**An agent can connect on its own if it already holds `X_API_KEY`, `X_API_KEY`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "salary-net": {
      "type": "http",
      "url": "https://syntropicapi.com/mcp/salary-net/mcp",

## Quality 96/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 5 of 5 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 4,123 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 5, about 4,123 tokens to load them all
- tool set hash: cbc6562eeb7a49935c0d9b634749d5bc
- badge: [![protogrid quality](https://protogrid.dev/badge/com.syntropicapi/salary-net.svg)](https://protogrid.dev/servers/com.syntropicapi/salary-net)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `calculate_gross_salary`: Finds the smallest gross pay (to the cent) whose net pay reaches the target, by bisection over the same engine
as /net. Returns the full breakdown for that gross pay and the remaining difference to the target.
- `calculate_net_salary`: Computes net pay from gross pay for one pay period with the country's official payroll algorithm.
Returns every employee deduction and employer contribution as a line with the rule applied and its source,
the employer's total cost, annualised figures and the assumptions made.
- `compare_net_salaries`: Runs up to 8 gross-to-net scenarios and returns them side by side: net, deductions, employer cost and the
split into income tax and social contributions. Amounts stay in each country's currency (no FX conversion).
- `get_payroll_parameters`: Allowances, tax bands, contribution rates and ceilings the engine uses for the country and year, each with
its official source.
- `list_salary_countries`: Coverage: which countries and tax years are available, which pay periods and profile fields they accept, the
official test data each engine is checked against, and which countries are planned next.
