## 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**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 795 tokens (~132/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 77/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 31% 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 current MCP spec version (2026-07-28).

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 66, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-02 (score 65, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

First indexed and scored.

## MCP tools (6)

### `roll_dice` (~113 tokens)

Roll dice

Roll 1 to 100 dice with 2 to 1000 sides each (default one six-sided die). The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

Input parameters:

- `count` (integer)
- `seed` (string): Optional. 64 hex characters. Give the seed shown on an earlier result page to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.
- `sides` (integer)

### `flip_coin` (~93 tokens)

Flip a coin

Flip a fair coin 1 to 100 times. The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

Input parameters:

- `count` (integer)
- `seed` (string): Optional. 64 hex characters. Give the seed shown on an earlier result page to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.

### `random_integer` (~137 tokens)

Random integers

Integers from min to max inclusive, 1 to 1000 of them, with or without repeats. The range may hold at most 2^32 values. The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

Input parameters:

- `count` (integer)
- `max` (integer, required)
- `min` (integer, required)
- `seed` (string): Optional. 64 hex characters. Give the seed shown on an earlier result page to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.
- `unique` (boolean)

### `pick_from_list` (~122 tokens)

Pick from a list

Pick 1 or more items from a list of up to 1000, each equally likely. Without repeats by default. The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

Input parameters:

- `count` (integer)
- `items` (array, required)
- `seed` (string): Optional. 64 hex characters. Give the seed shown on an earlier result page to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.
- `unique` (boolean)

### `shuffle_list` (~100 tokens)

Shuffle a list

Put up to 1000 items in a random order; every order is equally likely. The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

Input parameters:

- `items` (array, required)
- `seed` (string): Optional. 64 hex characters. Give the seed shown on an earlier result page to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.

### `prismtect_number` (~71 tokens)

Prismtect number (human touch only)

A personal two-digit number from the Prismtect glass prism, for a user who asks for a lucky number, a number of their own or a number for today. Only a human touch can draw it, so this tool gives no number: it gives the link your user taps themselves. Pass the link on.

## Common questions

### What is the Fair Random MCP server?

Fair Random is an MCP server listed in the public MCP registry as com.hanaprism/fair-random. Fair, reproducible randomness for agents: dice, coins, integers, list picks, shuffles, with seeds. This page covers its hosted endpoint (https://hanaprism.com/mcp/random).

### Is the Fair Random MCP server safe to use?

Fair Random scores 66 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 Fair Random MCP server expose?

Fair Random exposes 6 tools: roll_dice, flip_coin, random_integer, pick_from_list, shuffle_list, prismtect_number. Their descriptions and schemas cost roughly 636 tokens of context every time the server is loaded.

### Does the Fair Random MCP server require authentication?

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

### Is the Fair Random MCP server still maintained?

Fair Random 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.

### What did VerifyMCP test on the Fair Random MCP server?

VerifyMCP ran 12 checks on Fair Random, covering TLS certificate, Authorization, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about Fair Random: HTTPS. 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.
