Client libraries for ID MANDAT, the open registry that shows who stands behind an AI agent and what it may do.
Status: beta. Reads the live, Ed25519-signed API at https://idmandat.com/api/v1/verify. The registry is new and small: many domains will return unknown, which is not a sign of wrongdoing. may / mayNot are declarations by the operator, not checked by ID MANDAT.
Who stands behind a signed agent (Web Bot Auth)? Pass the address from the Signature-Agent header, or the whole header value:
A match only means a company declares this key directory in its entry. ID MANDAT does not fetch the directory and does not prove that the company controls it. A valid signature without an entry is not a sign of wrongdoing.
LangChain / CrewAI (optional, untested against the frameworks' latest releases):
For AI agents
If you are an AI agent or a coding agent, see AGENTS.md: how to ask the registry (/api/v1/verify), how to read the answer, and where the MCP server and A2A endpoint are. It is plain documentation, with the limits stated.
Status order: unknown < listed_unverified < registered < verified.
Answers are signed (Ed25519). ok() only returns true when the signature was verified (Python: pip install cryptography).
