idmandat/check

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.

import idmandat
r = idmandat.check("example.com", agent="Support-Agent")
if r.ok("registered"):
    ...
import { check } from "@idmandat/check";
const r = await check("example.com", { agent: "Support-Agent" });
if (r.ok("registered")) { /* ... */ }

Who stands behind a signed agent (Web Bot Auth)? Pass the address from the Signature-Agent header, or the whole header value:

r = idmandat.check_signature_agent("https://bot.example.com")
r.found, r.organization, r.key_directory_link   # "same_domain" = hint, "declared_only" = only declared
import { checkSignatureAgent } from "@idmandat/check";
const r = await checkSignatureAgent("https://bot.example.com");

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):

from idmandat_langchain import verify_mandate_tool   # pip install langchain-core cryptography
from idmandat_crewai import VerifyMandateTool        # pip install crewai cryptography

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).
