### The 36 tools it exposed

Every name below came back from this server's own tools/list response on the date above. So did each description, parameter list and label like "read-only": they are the server describing itself. We did not call any of them.

- check_agent (read-only, reaches outside services): Check whether an AI agent is registered in the Concordium Agent Registry (CIS-8004), Active (not revoked), and Verified by Concordium (its Agent Card hash matches the on-chain metadata_hash). Accepts a badge (CIS-2 token address, e.g. Mf22soLh1NuZYFgBK8iSs, or CAIP-19 form) or a Concordium owner account address. Free tier: returns the verdict; the full record is available from the paid x402 endpoint. [AgentGate via YourAITools MCP Hub] Free tier: same as AgentGate's own MCP server (call without payment and without tier). Paid: check $0.005 per call, with a credits key (Authorization: Bearer ya [shortened]
  - Parameters: id (required), network, tier
- read_url (read-only, reaches outside services): Fetches one public web page and returns its main content as clean Markdown (navigation, scripts, ads and boilerplate removed; links made absolute) plus title and metadata. Use it whenever your agent needs to read, quote or summarize a page. Respects robots.txt, refuses private/internal hosts and non-default ports, follows redirects, and handles HTML, plain text and Markdown (no JavaScript rendering). Free: 30 calls/day per IP with the full Markdown (max 10/min; failed reads are not counted); after that the tool returns an error with the x402 pay URL ($0.002 USDC on Base, Polygon, Arbitrum One [shortened]
  - Parameters: url (required), maxChars, tier
- scan_text (read-only, reaches outside services): Scans untrusted text for prompt injection before your agent reads or acts on it: web page text, emails, documents, tool results or another agent's message. Flags instruction overrides, jailbreak personas, system-prompt extraction, fake delimiters, exfiltration URLs, tool hijacking, hidden Unicode and encoded payloads (deterministic rules). Use scan_url when you only have a link (it also checks hidden HTML) and scan_tools for MCP tool definitions. Text up to 100000 characters.

Free: 30 calls/day per IP shared by scan_text, scan_url and scan_tools, with full results (max 10/min; invalid input is not counted).

Free: 30 calls/day per IP shared by scan_text, scan_url and scan_tools, with full results (max 10/min; invalid input is not counted).
