Dead
Every channel of this server has been unreachable for long enough to be marked dead. Its trust score is pinned to 0 and does not recover automatically: even once the server responds again it stays dead until it is manually reinstated.
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. How we score → Why this is hard to score →

Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the Casper Tools MCP server?
Casper Tools is a hosted endpoint at https://determines-product-administration-farmer.trycloudflare.com/, 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.

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 →

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.
