Anlyon alternative
4 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

biggest_gapsThe three upcoming games where CrystlQuant and the market disagree most, biggest gap first, including games where they back different winners.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it The three upcoming games where CrystlQuant and the market disagree most, biggest gap first, including games where they back different winners. Each row links to the game's page; every other disagreement is on crystlquant.com (the link comes with the answer). Quote each number as a forecast of who wins, naming the side and its chance (never 'coin flip', 'toss-up' or '50-50'). These are forecasts of who wins, not tips.

Description, as the server wrote it The games on CrystlQuant's board today and tomorrow, in start order: each matchup, its start time and CrystlQuant's pick, with a link to each game's page. The board carries no chances: for one game's CrystlQuant chance, call find_game with a team name; the market's chance and the gap are on the game's page. Quote each number as a forecast of who wins, naming the side and its chance (never 'coin flip', 'toss-up' or '50-50'). These are forecasts of who wins, not tips.

Description, as the server wrote it Title chances: each league's likeliest champions from CrystlQuant's season forecasts, with the change since the last update and a link to the league's page. A row with no CrystlQuant number yet shows the Blind model's chance and says so. The limit is per league.

Why it is in this group

Description, as the server wrote it CrystlQuant's pick and win chance for one upcoming game (today or tomorrow), found by a team or fighter name, for example 'Chiefs', 'Arsenal' or 'Pereira', with a link to the game's page, where the market's chance and the gap are.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Remote posture

- WarnThe whole server
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.
What this check looks forMatched text
https://crystlquant.com/mcp: tools/list returned 5 tools to an anonymous client, including todays_board (write), biggest_gaps (write), who_wins_it_all (write), rankings (write)
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
Install

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__crystlquant__find_game"
],
"ask": [

"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as crystlquant. Review it before you use it.
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
