Available components
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. How we score → Why this is hard to score →
Supply Chain Security0
- Malware scan not yet available for this package.Unverified
- 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.Unverified
- Install-script risk not yet assessed.Unverified
- 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.Unverified
Provenance & Transparency19
- Repository check failed: the declared repository URL returned HTTP 404. See how to fix → View diagnostics → Fail
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 8 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability86
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 1691 tokens (~17/item across 98 items; 6 tools + 92 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management30
- Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage98
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 93% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
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.
How do I install the Sampuli MCP server?
Sampuli runs locally as a container image, launched with docker run --rm -i ghcr.io/kevinbett/sampuli-mcp:0.1.3. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

Background: How many MCP packages publish verified provenance →
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
sampuli_describe_country Describe a country ~65
List a country's available fields (phone, national ID, tax number, IBAN, SWIFT/BIC, card, …) and preset scenarios.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | yes | ISO code, e.g. "ke", "de", "us", "ng". |
No output schema declared.
No examples provided.
sampuli_fetch Fetch data by plain-language request ~165
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".
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | How many (omit for one). |
| format | string | – | Output format (default json). |
| query | string | yes | Plain-language request, e.g. "a SWIFT code for China", "UK IBAN", "India GSTIN". |
| seed | string | – | Reproducible output. |
No output schema declared.
No examples provided.
sampuli_generate Generate synthetic test data ~203
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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". |
No output schema declared.
No examples provided.
sampuli_list_countries List Sampuli countries ~36
List every country Sampuli can generate synthetic test data for (90 countries), with the ISO code used as a spec prefix.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
sampuli_list_types List generic field types ~55
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>".
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
sampuli_schema Generate a custom dataset ~141
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.
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | How many rows (default 1). |
| fields | array | yes | The columns to generate. |
| format | string | – | – |
| seed | string | – | Reproducible output. |
No output schema declared.
No examples provided.
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.
