## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - The endpoint enforces authorisation, but returns a challenge with no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http.
- **Schema Quality & AI Usability**: 0/100
  - Schema blocked by authentication: the endpoint requires auth we don't have to read it.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Tool Safety**: 0/100
  - Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Capabilities**: 0/100
  - Capabilities blocked by authentication: the endpoint requires auth we don't have to read them.

**Unverified: 6 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

## MCP tools (1)

### `de_rates_lookup` (~418 tokens)

German rates lookup

Current German (Veranlagungszeitraum 2026) tax and social-insurance figures read from the consolidated statutes on gesetze-im-internet.de, the Bundesgesetzblatt and the BMG, DRV, BMAS, BMFSFJ and Minijob-Zentrale pages named in each figure's source — each with the German term and an English label, the quoted sentence, verifiedDate and the prior value where one exists. Categories: income-tax (Grundfreibetrag, § 32a tariff zones with their coefficients, Eingangssteuersatz, Spitzensteuersatz and Reichensteuer thresholds, Solidaritätszuschlag rate, Freigrenzen and Milderungszone), social-insurance (Beitragsbemessungsgrenzen RV/AV and KV/PV annual and monthly, Jahresarbeitsentgeltgrenze, Bezugsgröße, vorläufiges Durchschnittsentgelt, KV/RV/AV/PV Beitragssätze with employee and employer shares, durchschnittlicher Zusatzbeitrag, Kinderlosenzuschlag and Kinderabschlag, Sachsen split), minimum-wage (Mindestlohn 2026 and the fixed 2027 step), minijob (Geringfügigkeitsgrenze 2026 and 2027, Midijob upper limit), kindergeld, kinderfreibetrag (Kinderfreibetrag, BEA-Freibetrag, total per child), sparer-pauschbetrag, arbeitnehmer-pauschbetrag, entfernungspauschale. Federal law only: Kirchensteuer by Land, Lohnsteuerklassen mechanics and Gewerbesteuer are not covered, and 2027 draft figures are not served. An unknown category answers covered:false with the nearest keys.

Input parameters:

- `category` (string): one of: income-tax, social-insurance, minimum-wage, minijob, kindergeld, kinderfreibetrag, sparer-pauschbetrag, arbeitnehmer-pauschbetrag, entfernungspauschale (omit to list all)

## Common questions

### What is the io.github.physics-star-cat/databutler-de-rates MCP server?

io.github.physics-star-cat/databutler-de-rates is an MCP server listed in the public MCP registry as io.github.physics-star-cat/databutler-de-rates. German 2026 tax and social-insurance thresholds, minimum wage and allowances, sourced. This page covers its hosted endpoint (https://databutler.dev/api/mcp/de-rates).

### Is the io.github.physics-star-cat/databutler-de-rates MCP server safe to use?

io.github.physics-star-cat/databutler-de-rates scores 33 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.physics-star-cat/databutler-de-rates MCP server expose?

io.github.physics-star-cat/databutler-de-rates exposes 1 tool: de_rates_lookup. Their descriptions and schemas cost roughly 418 tokens of context every time the server is loaded.

### Does the io.github.physics-star-cat/databutler-de-rates MCP server require authentication?

Yes. io.github.physics-star-cat/databutler-de-rates asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the io.github.physics-star-cat/databutler-de-rates MCP server still maintained?

io.github.physics-star-cat/databutler-de-rates is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
