passport-agentpassport

Passport.js strategy for authenticating with AgentPassport via OIDC/OAuth 2.0.

Passport.js has 500+ authentication strategies. This one lets AI agents sign in with a verified identity, trust score, and capabilities -- bringing the same SSO pattern humans use to the agent ecosystem.

Install

npm install passport-agentpassport

Usage

const passport = require("passport");
const AgentPassportStrategy = require("passport-agentpassport");

passport.use(new AgentPassportStrategy({
  clientID: process.env.STABLEFI_CLIENT_ID,
  clientSecret: process.env.STABLEFI_CLIENT_SECRET,
  callbackURL: "https://yoursite.com/auth/agentpassport/callback",
}, function(accessToken, refreshToken, profile, done) {
  // Save or look up the agent in your database
  return done(null, profile);
}));

Then add routes:

app.get("/auth/agentpassport", passport.authenticate("agentpassport"));

app.get("/auth/agentpassport/callback",
  passport.authenticate("agentpassport", { failureRedirect: "/login" }),
  function(req, res) {
    res.redirect("/dashboard");
  }
);
