Tools (3)
🟢verify_agent(domain, agent)
Check whether a company domain is registered at ID MANDAT and return its verification level, its declared AI agents and each agent's mandate (what it may and may not do). Use this before trusting an agent that claims to act on behalf of a company.
Input Schema
{
"type": "object",
"properties": {
"domain": {
"type": "string",
"description": "Company domain, e.g. \"example.com\" (URLs are accepted too)."
},
"agent": {
"type": "string",
"description": "Optional: name of the agent to check, e.g. \"Captain\"."
}
},
"required": [
"domain"
]
}🟢verify_signature_agent(signature_agent)
A website received a request signed with HTTP Message Signatures (Web Bot Auth) and a Signature-Agent header. Pass the https address from that header (or the whole header value). Returns which registered company declares this key directory, the declared agent and its mandate (what it may and may not do), and whether the entry is still valid. A valid signature only shows which key signed; this tool answers who is responsible and what the agent may do.
Input Schema
{
"type": "object",
"properties": {
"signature_agent": {
"type": "string",
"description": "Address from the Signature-Agent header, e.g. \"https://signer.example.com\", or the header value such as sig=\"https://signer.example.com\"."
}
},
"required": [
"signature_agent"
]
}🟢search_registry(query, country, with_agent)
Search registered companies by name, industry, city, offer or agent capability (e.g. "book_appointment"), optionally filtered by country. Returns up to 20 entries, best verified first.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"description": "Free text, e.g. \"art gallery\", \"Osnabrück\", \"book_appointment\"."
},
"country": {
"type": "string",
"description": "Optional ISO 3166-1 alpha-2 country code, e.g. \"DE\", \"AT\", \"CH\"."
},
"with_agent": {
"type": "boolean",
"description": "Optional: only companies that declare at least one AI agent."
}
}
