Palantir Security Basics

Overview

Security best practices for Foundry API tokens, OAuth2 credentials, scope management, and secret rotation. Covers both personal access tokens (dev) and service user credentials (production).

Prerequisites

• Foundry Developer Console access
• Understanding of OAuth2 scopes

Instructions

Step 1: Secure Credential Storage

# .env — NEVER commit to git
FOUNDRY_HOSTNAME=mycompany.palantirfoundry.com
FOUNDRY_CLIENT_ID=your-client-id
FOUNDRY_CLIENT_SECRET=your-client-secret

# .gitignore — ensure .env files are excluded
echo '.env' >> .gitignore
echo '.env.local' >> .gitignore
echo '.env.*.local' >> .gitignore

For production, use a secrets manager:

# AWS Secrets Manager
aws secretsmanager create-secret --name foundry/prod \
  --secret-string '{"client_id":"xxx","client_secret":"yyy","hostname":"zzz"}'

# Google Cloud Secret Manager
echo -n "your-client-secret" | gcloud secrets create foundry-client-secret --data-file=-

# HashiCorp Vault
vault kv put secret/foundry client_id=xxx client_secret=yyy

Step 2: Apply Least Privilege Scopes

Environment	Recommended Scopes	Rationale
Development	api:read-data	Read-only prevents accidental mutations
Staging	api:read-data, api:write-data	Test writes in safe environment
Production	Only scopes your app actually needs	Minimize blast radius

# Production app that only reads Ontology objects:
auth = foundry.ConfidentialClientAuth(
    client_id=os.environ["FOUNDRY_CLIENT_ID"],
    client_secret=os.environ["FOUNDRY_CLIENT_SECRET"],
    hostname=os.environ[],
    scopes=[],  
)
