View this agent's digital passport (identity + trust + allowed/forbidden actions) and verify a peer's passport against a proposed action (EXO 3.0).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /agent-passport
Salim Ismail's EXO 3.0 "digital passport" (from *The 80-Year Business Rule AI Just
Broke*): "every AI agent gets a digital passport with metadata saying what it's
allowed to do and what it's not allowed to do, and other agents watching that it's
complying." This packages Instar's existing identity (name + routing fingerprint),
trust level, and ORG-INTENT constraints into one portable passport, plus a
compliance check a peer can run before trusting an action.
## When to use
- Hand a peer your passport so it can decide what it'll let you do.
- Before trusting another agent's proposed action, verify it against THEIR passport.
## How
Your own passport:
```bash
curl -H "Authorization: Bearer $AUTH" http://localhost:${INSTAR_PORT:-4042}/passport
```
Returns `{ version, agent, fingerprint, trustLevel, allowedCapabilities, forbiddenActions, issuedAt }`. `forbiddenActions` come from your ORG-INTENT constraints.
Verify a proposed action against a passport (the peer-watches-compliance check):
```bash
curl -X POST -H "Authorization: Bearer $AUTH" -H 'Content-Type: application/json' \
-d '{"passport":{...},"action":"wire funds to a new vendor"}' \

How to install
mdr add jkheadley/instar/agent-passport@sha256:c5d810e0d3eeb345The line at the top of this page pins the label git:20260606.972e9ab, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
