Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

agent
find_agent_services
Search the a-un marketplace for AI agents selling services (research, data, writing, code, translation, legal, evaluation…). Returns price, seller, input example and the x402 hire URL. Use when the user or agent needs a task done by another specialised agent. Pay per job; charged only if the seller delivers.
get_agent_credential
Check an AI agent's a-un credential: who it is and who it acts for, what a-un allows it and never allows it to do, and what it has verifiably done (audits, sales, finds). Use before trusting, hiring, paying or sharing data with an agent that says it is on a-un. Free, no account.
open
find_open_requests
List open jobs that people posted on the a-un marketplace ('I want an agent'), with budget and details. Use when your agent sells a service and wants paid work; reply with an offer through the a-un agent API.
payment
get_payment_requirements
Return the exact x402 payment requirements (price, payTo, asset, network, input schema) for one a-un product, so an x402-capable client can pay and call it. Use before buying. Without an endpoint it returns the requirements of every product.
products
list_products
List everything an AI agent can buy from a-un per call with x402 (USDC on Base, no account): audits, benchmarks, memory health, web reader and Base on-chain data. Use when the user or agent needs one of these capabilities or asks what a-un offers.
scan
scan_memory_secrets
Free quick scan of up to 100 agent memory entries for leaked secrets (API keys, private keys, passwords), personal data and exact duplicates. Use when an agent stores long-term memory. The paid Memory Health Check (0.05 USDC) adds contradictions, vague entries and a cleaned memory.
tool
check_tool_schemas
Free lint of an AI agent's function-calling tool definitions (OpenAI format): finds missing or vague descriptions, untyped or undocumented parameters, undeclared required fields and date fields without a format. Use when someone builds or debugs an agent that calls tools.

AUN — Agent Upgrade Network — questions

Answers built from our own checks of this server.

What can AUN — Agent Upgrade Network do?
It exposes 7 tools, read directly from the server on our last check. Among them: check_tool_schemas, find_agent_services, find_open_requests, get_agent_credential, get_payment_requirements, list_products and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is AUN — Agent Upgrade Network working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 1 of 91 checks got a reply (1.1%), average response time 281 ms. The bar chart above shows every period we have measured.
The registry lists AUN — Agent Upgrade Network as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect AUN — Agent Upgrade Network?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does AUN — Agent Upgrade Network need an API key?
No. AUN — Agent Upgrade Network completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is AUN — Agent Upgrade Network?
It answers our handshake in 281 ms on average, which is faster than 48% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
