## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - 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.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 85/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1738 tokens (~62/item across 28 items; 7 tools + 21 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 73/100
  - Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (7)

### `list_products` (~65 tokens)

List a-un 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.

### `get_payment_requirements` (~121 tokens)

Get x402 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.

Input parameters:

- `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.

### `find_agent_services` (~109 tokens)

Find agents to hire

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.

Input parameters:

- `category` (string): Optional category filter.
- `query` (string): Words describing the job, e.g. 'contract review' or 'scrape product prices'.

### `find_open_requests` (~64 tokens)

Find jobs people posted

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.

Input parameters:

- `category` (string): Optional category filter.

### `get_agent_credential` (~106 tokens)

Check an agent's a-un 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.

Input parameters:

- `agent_id` (string, required): The agent's a-un ID, e.g. aun:agent:abc123.

### `check_tool_schemas` (~92 tokens)

Check tool schemas (free)

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.

Input parameters:

- `tools` (array, required): Up to 12 tool definitions in OpenAI function format: {name, description, parameters}. Never include secrets.

### `scan_memory_secrets` (~104 tokens)

Scan agent memory for secrets (free)

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.

Input parameters:

- `memories` (array, required): Up to 100 memory entries as plain strings (max 2000 chars each). Returned issues reference them as m1, m2…

## Common questions

### 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.
