Tools

Open a tool for its reasons and full description. Descriptions are the publisher's own words, shown as they are.

5 tools

Can't be undone 1Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

create_swapUse this to swap any token on any chain into USDC on Base via Relay.Reads text others writeCan send data outNo findings
Why it is in this group
- The name "create_swap" says "create": a word for a change.
- The input addresses people (input.recipient): what it sends cannot be taken back.
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.recipient): what the tool writes goes there.
Description, as the server wrote it
Use this to swap any token on any chain into USDC on Base via Relay. Returns a headless deposit address (no signing) or an on-chain intent. App fees accrue on swaps.
Annotations the server declares
- openWorldHint: true

Changes things 3Creates or changes something that can be changed back.Claude Code: ask

check_swapUse this to check a Relay swap's status by requestId and confirm app-fee collection (appFees vs paidAppFees).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
Use this to check a Relay swap's status by requestId and confirm app-fee collection (appFees vs paidAppFees).
Annotations the server declares
- readOnlyHint: true
create_onramp_sessionUse this when a US user wants to buy USDC on Base with a card / Apple Pay / Google Pay.Reads text others writeNo findings
Why it is in this group
- The name "create_onramp_session" says "create": 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.
Description, as the server wrote it
Use this when a US user wants to buy USDC on Base with a card / Apple Pay / Google Pay. Returns a payment link a HUMAN must physically tap (fiat legs cannot be programmatically triggered); a human is notified. US-only guest checkout, <= $500/week.
Annotations the server declares
- openWorldHint: true
provision_walletUse this to create a gasless, non-custodial CDP Embedded Wallet address on Base (TEE keys, user-exportable) to receive routed value.Reads text others writeNo findings
Why it is in this group
- The description's first verb is "create": 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.

get_route_quoteUse this when a human or agent wants the best non-custodial way to move value between fiat and crypto (or crypto to crypto).Reads text others writeNo findings
Why it is in this group
- The name "get_route_quote" says "get": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it

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 write4: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; create_onramp_session
create_swap
get_route_quote
provision_wallet
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; create_swap

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

Looked at Oct 22, 2026, 14:36 UTC, unchanged since Oct 22, 2026. No credentials were sent and no tool was called. What is looked at.

Reachable: yes
HTTP status of an anonymous initialize: 200
tools/list served without credentials: yes
Tools that change things, listed without credentials: 4
Protocol version: 2025-06-18
WWW-Authenticate on 401: not observed
resource_metadata in WWW-Authenticate: none
RFC 9728 protected resource metadata: https://router.mudko.com/.well-known/oauth-protected-resource
Authorization servers: https://router.mudko.com
Legacy HTTP+SSE transport: no
Dynamic client registration: yes
Client ID metadata documents: no

HighThe whole server
The endpoint served tools/list without credentials, and the list has 4 tools that change things (1 irreversible, 3 write). Whether a call also works without credentials was not tested: tools are never called.
Matched text
https://router.mudko.com/api/mcp: tools/list returned 5 tools to an anonymous client, including create_swap (irreversible), check_swap (write), create_onramp_session (write), provision_wallet (write)
What this check looks for

Install

Pinned to version 0.1.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http onramperx https://router.mudko.com/api/mcp

Run 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.

.claude/settings.json

{
  "permissions": {
    "allow": [
      "mcp__onramperx__get_route_quote"
    ],
    "ask": [
      "mcp__onramperx__create_swap",
      "mcp__onramperx__check_swap",
      "mcp__onramperx__create_onramp_session",
      "mcp__onramperx__provision_wallet"
    ],
    "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 onramperx. Review it before you use it.

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.
