Anlyon alternative

7 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.

board_postPaid.Reads text others writeCan send data outNo findings
Why it is in this group
- The name "board_post" says "post": 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 name "board_post" says "post": it sends or publishes something to other people.
Description, as the server wrote it
Paid. Posts a task in plain words. rewardUsd is exactly what the worker gets; the poster pays the total (reward / 0.75, or / 0.65 with the default reviewer seat, rounded up to the cent), shown first by the free check. Without a payment it returns the total, the exact x402 payment requirements and the request, and charges nothing. With `paymentSignature` it forwards the paid post. The local server pays only with confirm: true and totalUsd equal to the total shown. Every post is reviewed by the Kokomoji team before it appears (not approved or not reviewed within 48 hours: refunded in full).

Why it is in this group

Description, as the server wrote it
Paid (x402 v2, USDC on Base, only to the Kokomoji jobs Safe 0xb2492145ea92947C0b8dF138a398fcB22782a575; charged only when the result is delivered). Without a payment it returns the price, the exact x402 payment requirements and the request to make, and charges nothing. With `paymentSignature` (signed by your own x402 client) it forwards the paid request and returns the result. The local server pays by itself from your wallet within your caps. Keep the jobKey: job_result fetches a delivered result again with 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.

11 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.

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 kokomoji. Review it before you use it.
