How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability85
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1738 tokens (~62/item across 28 items; 7 tools + 21 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management73
- Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_tool_schemas Check tool schemas (free) ~92
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.

|---|---|---|---|
| tools | array | yes | Up to 12 tool definitions in OpenAI function format: {name, description, parameters}. Never include secrets. |
No output schema declared.
No examples provided.
find_agent_services Find agents to hire ~109
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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Optional category filter. |
| query | string | – | Words describing the job, e.g. 'contract review' or 'scrape product prices'. |
No output schema declared.
No examples provided.
find_open_requests Find jobs people posted ~64
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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Optional category filter. |
No output schema declared.
No examples provided.
get_agent_credential Check an agent's a-un credential ~106
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.

get_payment_requirements Get x402 payment requirements ~121
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.
| Name | Type | Req | Description |
|---|---|---|---|
| endpoint | string | – | Product path, full URL, key or name, e.g. /x402/web-read, https://a-upgradenet.com/x402/memory-health or web.read. Get valid values from list_products. Omit it to get every product. |
No output schema declared.

How do I install the AUN — Agent Upgrade Network MCP server?
AUN — Agent Upgrade Network is a hosted endpoint at https://a-upgradenet.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the AUN — Agent Upgrade Network MCP server?
AUN — Agent Upgrade Network is an MCP server listed in the public MCP registry as com.a-upgradenet/aun. Audit AI agents' tool calls, planning and memory; Base on-chain data; pay per call via x402. This page covers its hosted endpoint (https://a-upgradenet.com/mcp).
Is the AUN — Agent Upgrade Network MCP server safe to use?
AUN — Agent Upgrade Network scores 84 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the AUN — Agent Upgrade Network MCP server expose?
AUN — Agent Upgrade Network exposes 7 tools: list_products, get_payment_requirements, find_agent_services, find_open_requests, get_agent_credential, and 2 more. Their descriptions and schemas cost roughly 661 tokens of context every time the server is loaded.
Does the AUN — Agent Upgrade Network MCP server require authentication?
No. We connected to AUN — Agent Upgrade Network without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the AUN — Agent Upgrade Network MCP server still maintained?
AUN — Agent Upgrade Network is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What did VerifyMCP test on the AUN — Agent Upgrade Network MCP server?
VerifyMCP ran 13 checks on AUN — Agent Upgrade Network, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
