## 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 2026-11-06.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 550 tokens (~110/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 81/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 43% 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 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 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.

## Install

### How do I install the MINIMALCULT MCP server?

MINIMALCULT is a hosted endpoint at https://ai.minimalcult.org/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (5)

### `check` (~193 tokens)

Check before you trust

Check an MCP server, an npm or PyPI package (optionally with the hash you are about to install), an MCP endpoint URL or a TON address against the anchored record. Returns a signed check: status (witnessed, changed_recently, hash_mismatch, not_witnessed, sanctions_listed, not_listed), flags, facts, recent changes with diff links.

Input parameters:

- `as_of` (string): RFC 3339 time: answer as the record stood at that moment
- `integrity` (string): npm dist.integrity of the tarball you are about to install
- `sha256` (string): sha256 of the PyPI file you are about to install
- `target` (string, required): registry name (io.github.owner/server), npm:<name> or pypi:<name>, https URL, or TON address
- `type` (string, required)
- `version` (string)

### `monitor_create` (~102 tokens)

Watch a record

Subscribe a webhook to changes of a record (new version, tool description changed, removed). Returns the monitor id and a secret shown once (HMAC-SHA256 signatures, header MINIMALCULT-Signature). 3 monitors per address are free.

Input parameters:

- `record` (string, required): rec_ id or mcp:<registry name>, npm:<name>, pypi:<name>
- `url` (string, required): public https URL that receives monitor.triggered events

### `record_search` (~59 tokens)

Search the record

Find records of MCP servers and npm/PyPI packages by name or words; returns rec_ ids, on-record-since dates, latest versions.

Input parameters:

- `limit` (integer)
- `query` (string, required)
- `type` (string)

### `record_get` (~47 tokens)

Get a record

One record by rec_ id or source id (mcp:<registry name>, npm:<name>, pypi:<name>) with its latest recorded fact.

Input parameters:

- `id` (string, required)

### `record_versions` (~50 tokens)

List recorded facts

The recorded facts (versions, registry entries, package artifacts, tool descriptions) of a record, newest first, with proof and diff links.

Input parameters:

- `id` (string, required)
- `limit` (integer)

## Common questions

### What is the MINIMALCULT MCP server?

MINIMALCULT is an MCP server listed in the public MCP registry as org.minimalcult/minimalcult. Check MCP servers and packages against an independent, anchored record before you trust them. This page covers its hosted endpoint (https://ai.minimalcult.org/mcp).

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

MINIMALCULT scores 72 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 MINIMALCULT MCP server expose?

MINIMALCULT exposes 5 tools: check, monitor_create, record_search, record_get, record_versions. Their descriptions and schemas cost roughly 451 tokens of context every time the server is loaded.

### Does the MINIMALCULT MCP server require authentication?

No. We connected to MINIMALCULT without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the MINIMALCULT MCP server still maintained?

MINIMALCULT is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the MINIMALCULT MCP server?

VerifyMCP ran 13 checks on MINIMALCULT, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
