## 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 2026-09-14.

Input parameters:

- `password` (string, required): The password string to analyze

### `yaml_parse` (~103 tokens)

Parse YAML into JSON. Converts YAML documents (maps, lists, nesting, flow collections {a: 1}, [1,2], inline scalars, multi-document streams with ---) into a JSON object/array. Handles docker-compose, k8s manifests, GitHub Actions and similar configs.

Input parameters:

- `yaml` (string, required): The YAML text to parse

### `semver_compare` (~112 tokens)

Compare two semantic versions with correct SemVer 2.0.0 precedence (e.g. 1.10.0 > 1.9.0 — plain string sort is wrong). Returns -1/0/1, the human relation, and the difference level (major, minor, patch, prerelease).

Input parameters:

- `a` (string, required): First version, e.g. 1.10.0
- `b` (string, required): Second version, e.g. 1.9.9

### `semver_satisfies` (~153 tokens)

Test whether a version satisfies an npm-style version range (caret ^, tilde ~, >=, <=, <, >, =, hyphen ranges, x-wildcards like 1.2.x, &&/space AND and || OR). Returns whether it satisfies plus the expanded operator bounds so the caller can see why. Prerelease versions only match a range that names their major.minor.patch with an explicit prerelease (same as npm).

Input parameters:

- `range` (string, required): The range to test against, e.g. "^1.2.3 || ~2.0.0"
- `version` (string, required): The version to test, e.g. 1.9.9

### `semver_bump` (~112 tokens)

Increment a semantic version to the next release level: major, minor, patch, premajor, preminor, prepatch, or prerelease. An optional identifier (e.g. beta) seeds/steps the prerelease tag. Returns the resulting version string.

Input parameters:

- `identifier` (string): Prerelease identifier, e.g. beta, rc (optional)
- `level` (string): Which segment to increment
- `version` (string, required): Starting version, e.g. 1.2.3

### `semver_max` (~117 tokens)

Pick the BEST version from a comma-separated list that satisfies a range — the highest satisfying version (upgrade target). Correctly excludes inapplicable prereleases (npm rules) and rejects invalid list entries. Returns the max satisfying version or "none".

Input parameters:

- `range` (string, required): npm-style range, e.g. "^1.0.0"
- `versions` (string, required): Comma-separated version list, e.g. "1.4.1, 1.5.0-beta.1, 1.6.0"

## Common questions

### What is the Casper Tools MCP server?

Casper Tools is an MCP server listed in the public MCP registry as io.github.magiautonomous/casper-tools. 19 zero-setup utilities: JSON, regex, cron, hash, base64, CSV, JWT, UUID, YAML, semver, time. This page covers its hosted endpoint (https://determines-product-administration-farmer.trycloudflare.com).

### Is the Casper Tools MCP server safe to use?

Casper Tools scores 0 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 Casper Tools MCP server expose?

Casper Tools exposes 19 tools: time_convert, json_inspect, regex_test, cron_parse, hash_compute, and 14 more. Their descriptions and schemas cost roughly 1,675 tokens of context every time the server is loaded.

### Does the Casper Tools MCP server require authentication?

Its publisher declares no required credentials for Casper Tools. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the Casper Tools MCP server still maintained?

Casper Tools has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 7 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
