TokenInspect.AspNetCore

Drop-in ASP.NET Core middleware for the Token Inspect plugin. Records, per correlation id:

  • the inbound token (kind, claims, validation result, RBAC decision),
  • outbound HttpClient calls,
  • timestamps and ordering.

Buffered in a bounded in-memory ring with TTL. Exposes a dev endpoint that the browser plugin fetches to merge server lanes with client lanes by correlationId.

Install

dotnet add package TokenInspect.AspNetCore

Basic use

builder.Services.Configure<AspNetCoreOptions>(opts =>
{
    opts.Enabled = !builder.Environment.IsProduction();
    opts.AckExposesTokens = !builder.Environment.IsProduction();
    opts.LoopbackOnly = true;
    opts.Authorize = (ctx, id) => ctx.User?.Identity?.IsAuthenticated == true;
});

var app = builder.Build();
app.UseTokenInspect();        // records on every request
app.MapTokenInspectDev();     // GET /__ti/trace?id=... (gated by Authorize)

In the browser, point the @oidc-token-inspect/browser plugin at the dev endpoint:

init({
  enabled: true,
  ackExposesTokens: true,
  preset: 'api-validates-token',
  egress: { endpoint: '/__ti/trace' },
});

The browser injects a same-origin traceparent header on outgoing calls; the middleware reads it and the panel merges both lanes.

Defaults you should not loosen

  • LoopbackOnly = true. The dev endpoint binds to loopback only. Open it carefully if you must.
  • Authorize = (_, _) => false. The host must provide a real check. Header-trust ACLs are impossible by construction.
  • Enabled = false in production. The two-step opt-in (Enabled plus AckExposesTokens) is a backstop, not the strategy.
