API keys

Manage hg_live_ and hg_test_ keys for Hangar MCP endpoints.

Key types

hg_live_

Production keys. Rate limits and credit costs apply. Use in server-side code only — never in client bundles or public repos.

hg_test_

Sandbox keys. Requests hit the Hangar MCP sandbox environment. No credits consumed.

Creating a key

Go to Settings → API Keys → New Key. Choose a name, select the key type, and set the scopes you need. The plaintext key is shown only once at creation — copy it immediately.

scopes
# Available scopes:
# tools:read     — call Hangar MCP tools
# tools:write    — publish new MCP tool endpoints
# usage:read     — read usage logs and credit ledger
# admin          — manage keys and org settings (use sparingly)

Securing your keys

  • Never commit hg_live_ keys to version control
  • Never embed live keys in client-side JavaScript
  • Store in environment variables and read at runtime
  • Use hg_test_ keys during local development
  • Rotate keys immediately if you suspect a leak — Hangarvibe auto-redacts known key formats from agent context
