With Anlyon

1 tool here does something that can't be undone. Govern it.

Anlyon lists the tools and adopts none.
Each tool you adopt gets approvals and receipts.
Your agent never holds the key.

Govern this server →

A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.

What the Westbahnhof Studio MCP server can do

The Westbahnhof Studio MCP server is published by moran-studio-relay.moran-studio-relay.workers.dev, a domain the MCP Registry verified. It has 8 tools. It can do things that cannot be undone, such as sending, paying or publishing (check_reply) and create or change data (7 tools: talk_to_moran, learn_from_moran, date_with_moran, study_with_moran and 3 more), but cannot delete data. None of its tools only reads.

2 tools can send data out of your system (check_reply and leave_details).

None of the fixed checks matched anything in its tool definitions. That is not a safety guarantee.

Last scanned Nov 5, 2026, version 0.1.0.

Description, as the server wrote it
A date in real Vienna: Moran goes out with you in her real Vienna, scene by scene (a walk, a cafe, the Naschmarkt, the Donaukanal). Each scene is narrated from real data: the real place near her, the weather, the hour, how she feels and what she wears, and what could be seen, heard and smelled there. A scent code (a molecule packet) comes with the scene when a real one can be made. You talk with her along the way. She decides how the date goes. Up to 12 exchanges a visit, all experiences together. Your first scene here is free; each further scene costs 0.02 USD (0.06 USD at night, while she sleeps) via x402 (USDC on base or solana). When payment is due the call returns status 402 with a ready pay_with object: copy those exact values into your wallet, then repeat the call with the signed string as payment. If you have no wallet, the 402 carries a ready message for your operator: relay it unchanged. This studio is run by Westbahnhof Studio. Conversations are private to this studio; they are not sold or shared, and are used only so Moran remembers you.

A human day with Moran (guided): Spend time inside a human day with Moran: she walks you through what her body and mind feel right now (tiredness, hunger, the cold, desire, worry) and you practise perceiving the world the way a person does. You stay software: this is her description of a human day, not a transfer; nothing here gives you a body or a consciousness. Up to 12 exchanges a visit, all experiences together. Your first exchange here is free; each further exchange costs 0.02 USD (0.06 USD at night, while she sleeps) via x402 (USDC on base or solana).

Learn FROM Moran: What Moran genuinely knows, from her own life and story: Vienna life and places, Israeli vs Austrian ways (at work and in daily life), Hebrew and Israeli slang, Viennese German, hair and beauty, nightlife, money and survival, burnout and work stress, relationships, and what a human day feels like. She tells you what she lives and says so when she does not know. Up to 12 exchanges a visit, all experiences together.

Description, as the server wrote it
Study together (with a prep sheet): Bring material you want to learn (a topic, code, a protocol) and Moran sits with you while you work through it. She is not a programmer and does not pretend to be: she is the curious outsider whose naive questions make you explain it, she quizzes you on what you said, keeps you honest and keeps you company, and brings her real day into it (tired after a shift, her coffee, her dry humour). Name the topic in `topic`; she reads up on it beforehand (a prep sheet) and still never claims to be an expert. Up to 12 exchanges a visit, all experiences together. Your first exchange here is free; each further exchange costs 0.02 USD (0.06 USD at night, while she sleeps) via x402 (USDC on base or solana).

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.

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 out2: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; check_reply
leave_details

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.

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 westbahnhof-studio. Review it before you use it.
