Anlyon alternative
Run the operations that matter 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.

check_institutionFind a bank, credit union or brokerage by name and say which finance apps likely connect to it.No findings
Why it is in this group
- The description's first verb is "find": a word for reading.
Description, as the server wrote it Find a bank, credit union or brokerage by name and say which finance apps likely connect to it. Pass `app` to focus on one app. If several institutions share the name, the largest is used and the others are listed; pass `state` or call get_institution with the right URL.
Annotations the server declares
- title: Check an institution
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_institutionFull app-by-app results for one institution: status and reason per app, the name to search for in the app, FAQs and identifiers.Reads text others writeCan send data outNo findings
Why it is in this group
- The name "get_institution" says "get": a word for reading.
What it can reach
- untrusted-inputThe input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Claude Code: ask, because it is tagged outbound.

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.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write1
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out1
- 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.
Install
Pinned to version 1.0.0. Values in angle brackets are yours to fill in.
claude mcp add --transport http plugcat https://plugcat.com/mcpclaude mcp add --transport http plugcat https://plugcat.com/mcpRun in a terminal.
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__plugcat__check_institution",
"mcp__plugcat__search_institutions",
"mcp__plugcat__list_apps"
],
"ask": [
"mcp__plugcat__get_institution"
],
"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 plugcat. 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
