## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-09-20.

- **Supply Chain Security**: 0/100
  - Malware scan not yet available for this package.
  - Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.
- **Provenance & Transparency**: 19/100
  - Repository check failed: the declared repository URL returned HTTP 404.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 8 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 86/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1691 tokens (~17/item across 98 items; 6 tools + 92 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 98/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 93% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Install

First indexed and scored.

## MCP tools (6)

### `sampuli_list_countries` (~36 tokens)

List Sampuli countries

List every country Sampuli can generate synthetic test data for (90 countries), with the ISO code used as a spec prefix.

### `sampuli_describe_country` (~65 tokens)

Describe a country

List a country's available fields (phone, national ID, tax number, IBAN, SWIFT/BIC, card, …) and preset scenarios.

Input parameters:

- `country` (string, required): ISO code, e.g. "ke", "de", "us", "ng".

### `sampuli_generate` (~203 tokens)

Generate synthetic test data

Generate format-true, entirely synthetic test data for a country. spec is "<country>.<selector>" where selector is a field key ("phone"), "person" (a full coherent record), or "preset:<key>" (a scenario). Values match each country's real formats and pass validators (IBAN mod-97, card Luhn, …) but are never real or registered.

Input parameters:

- `count` (integer): How many rows (omit for one).
- `fields`: Which fields for a person record, or "all".
- `format` (string): Output format (default json).
- `seed` (string): Reproducible output — same seed, same data.
- `spec` (string, required): e.g. "ke.person" (core fields), "ke.full" (every field incl. card/passport/income), "de.iban", "ng.phone", "ke.company", "ke.product", "ke.preset:kyc".

### `sampuli_fetch` (~165 tokens)

Fetch data by plain-language request

Fetch synthetic test data from a natural request when you don't know the exact spec — e.g. "a SWIFT code for China", "Kenya phone number", "German passport", "a Nigerian BVN". Sampuli resolves the country and field for you (China→cn, "SWIFT code"→swift) and generates a format-true value. Prefer sampuli_generate when you already have a spec like "cn.swift".

Input parameters:

- `count` (integer): How many (omit for one).
- `format` (string): Output format (default json).
- `query` (string, required): Plain-language request, e.g. "a SWIFT code for China", "UK IBAN", "India GSTIN".
- `seed` (string): Reproducible output.

### `sampuli_list_types` (~55 tokens)

List generic field types

List the country-agnostic generic types (uuid, enum, int, float, date, vin, isbn, imei, mac, email, …) usable in a custom schema or as "any.<type>".

### `sampuli_schema` (~141 tokens)

Generate a custom dataset

Generate rows from a custom schema, mixing generic types and country-accurate fields. Each field has a name and a type — a generic type ("uuid", "int:0,500", "enum:free,pro,team", "date:2021,2025") or a country field spec ("ke.phone", "de.iban"). Optional per-field "blank" (0–1) makes it null that often.

Input parameters:

- `count` (integer): How many rows (default 1).
- `fields` (array, required): The columns to generate.
- `format` (string)
- `seed` (string): Reproducible output.

## Common questions

### What is the Sampuli MCP server?

Sampuli is an MCP server listed in the public MCP registry as io.github.kevinbett/sampuli. Format-true synthetic test data for 90 countries, IBANs, SWIFT/BIC, IDs, cards, all certified. This page covers its container image (ghcr.io/kevinbett/sampuli-mcp:0.1.3).

### Is the Sampuli MCP server safe to use?

Sampuli scores 41 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 Sampuli MCP server expose?

Sampuli exposes 6 tools: sampuli_list_countries, sampuli_describe_country, sampuli_generate, sampuli_fetch, sampuli_list_types, sampuli_schema. Their descriptions and schemas cost roughly 665 tokens of context every time the server is loaded.

### Is the Sampuli MCP server still maintained?

Sampuli is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Sampuli MCP server under?

Sampuli declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
