Anlyon alternative
2 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.

search_chronodrawerSearch ChronoDrawer, a month-by-month database (1960-2026) of what happened and what was released around the world: events, Japanese laws, openings, sports, music, films, TV, anime…Reads private dataNo findings
Why it is in this group
- The name "search_chronodrawer" says "search": a word for reading.
What it can reach
- private-dataThe description's first sentence says "search" and "database": it reads databases.
Description, as the server wrote it Search ChronoDrawer, a month-by-month database (1960-2026) of what happened and what was released around the world: events, Japanese laws, openings, sports, music, films, TV, anime, games, manga, books, magazines, prizes, cars, mobile phones. Matches titles, English titles and people (artists, directors, authors). Japanese and English queries both work; person_match is true when one of the item's people is exactly the query. Returns dates (YYYY-MM-DD, or YYYY-MM when only the month is known), countries, date type and a source URL.
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 untrusted-input or outbound.
- Reads private data2
- 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.
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.

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__chronodrawer__search_chronodrawer",
"mcp__chronodrawer__get_month",
"mcp__chronodrawer__on_this_day",
"mcp__chronodrawer__get_entity"
],
"ask": [
"mcp__chronodrawer__person_timeline",
"mcp__chronodrawer__report_correction"
],
"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 chronodrawer. Review it before you use it.
