Anlyon alternative
1 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.

Changes things 1Claude Code: ask
request_bookingBooks the quoted ride.Reads text others writeCan send data outNo findings
Why it is in this group
- The name "request_booking" says "request": a word for a change.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a destination (input.phone): what the tool writes goes there.
Description, as the server wrote it Books the quoted ride. Call ONLY after the customer has seen the quoted total and deposit and has explicitly approved it and accepted the Terms (https://www.jetcabams.nl/terms.html). Send exactly the same ride fields as the get_quote call plus its unchanged quoteToken and the customer's real contact details. Fixed rides: the customer first gets an email with a Confirm link (valid 24 hours); after the click the driver confirms by email, payment in the car. Tours and custom rides: returns checkoutUrl for the 25% Mollie prepayment, which the customer must open and pay. Repeating the identical call does not create a second booking.

Why it is in this group
- The name "get_quote" says "get": a word for reading.
What it can reach
- private-dataThe description's first sentence says "email": it reads mail.
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- untrusted-inputThe description's first sentence says "email": it reads inbound email, which other people can write.
Description, as the server wrote it Exact price and rule check for one ride (no booking, no email, no payment). Returns the total, any online deposit and a quoteToken valid for 15 minutes. Per type: fixed needs routeId, direction and address; custom needs pickup and dropoff; tour needs tourIds and pickup. Fixed fares only apply inside each route's zone: error address_zone means quote a custom ride instead. Does not check driver availability.

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.
2 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.
- Reads private data1
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write2
- 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.
{
"permissions": {
"deny": [
"mcp__booking__request_booking"
]
}
}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

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__booking__list_services",
"mcp__booking__get_quote"
],
"ask": [
"mcp__booking__request_booking"
],
"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 booking. Review it before you use it.
Capability tags behind 2 rules
- mcp__booking__get_quote private-data, untrusted-input
- mcp__booking__request_booking untrusted-input, outbound
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
