Configuration¶

Every setting is an environment variable, read once at boot. The only required one is the secret key; everything else has a default that is safe on localhost.

Required¶


`PRODPEEK_SECRET_KEY`	Encrypts stored credentials, signs the session cookie. `prodpeek gen-key`. The process refuses to start without it.

Paths¶

	Default
`PRODPEEK_DATA_DIR`	`data`	Instance state, audit log, proofs, caches
`PRODPEEK_DB`	`$DATA/prodpeek.db`
`PRODPEEK_AUDIT_LOG`	`$DATA/audit.jsonl`
`PRODPEEK_PROFILES_DIR`	unset	An overlay on the bundled catalog. Loads as `local`, may only narrow
`PRODPEEK_CATALOG_DIR`	unset	Replaces the bundled catalog. Development and testing only

The policies ship inside the image; there is nothing to mount.

Network¶

	Default
`PRODPEEK_HOST`	`127.0.0.1`	`0.0.0.0` in the container
`PRODPEEK_PORT`	`8787`

Before it leaves localhost¶

	Default
`PRODPEEK_SESSION_HTTPS_ONLY`	`false`	Marks the session cookie Secure. Turn on once TLS is in front
`PRODPEEK_LOGIN_MAX_ATTEMPTS`	`10`	Failed sign-ins per window per address. `0` disables
`PRODPEEK_LOGIN_WINDOW`	`300`	Seconds

Warning

PRODPEEK_SESSION_HTTPS_ONLY=true with no TLS actually in front means nobody can sign in. That is the correct failure.

Proving and monitoring¶

	Default
`PRODPEEK_PROVE_INTERVAL`	`3600`	Seconds between proof runs. `0` disables the schedule
`PRODPEEK_MONITOR_TICK`	`5`	Scheduler tick. `0` disables monitoring

The feed and the kill switch¶

All optional. With none of it set, Prodpeek makes no outbound connection and enforces exactly what it always did — deny-by-default is local.

	Default
`PRODPEEK_CONTROL_URL`	unset	The control plane. Unset means no egress, ever
`PRODPEEK_CHECKIN_INTERVAL`	`300`
`PRODPEEK_FEED_KEYS`	unset	`key_id:base64` pairs whose feeds this instance believes
`PRODPEEK_FEED_FILE`	unset	A signed feed on disk, for air-gapped instances
`PRODPEEK_ON_REVOKED`	`block`	Revocation is the only state that blocks by default
`PRODPEEK_ON_STALE`	`warn`
`PRODPEEK_ON_DRIFT`	`warn`	`block` makes a drifted service unavailable
`PRODPEEK_ON_MODIFIED`	`warn`

Licence¶

	Default
`PRODPEEK_LICENSE_ENFORCE`	`false`	With it on, an instance past its trial refuses `/mcp`
`PRODPEEK_LICENSE_KEY`	unset

The gate is scoped to /mcp. Console, API, monitoring, incidents and prove keep working regardless.

Adapters¶

	Default
`PRODPEEK_SSH_KNOWN_HOSTS`	`$DATA/known_hosts`	Where host keys are pinned
`PRODPEEK_SSH_POOL_TTL`	`300`	How long an authenticated connection is reused
`PRODPEEK_GIT_CACHE_DIR`	`$DATA/git`	Bare mirrors
`PRODPEEK_GIT_FETCH_TTL`	`300`	How long a mirror is reused before refetching

The built-in adapters run in-process by default. Setting PRODPEEK_{SSH,PG,GIT,PROM}_ADAPTER_URL puts one back behind HTTP — same adapter, same menu, reached over a network instead.

AI¶

Not an environment variable. The provider key is set in the console, under Settings → AI, and PUT /api/v1/settings refuses it with secret_not_accepted.

That is deliberate: an agent holding an admin key should not be a courier for your provider key either. Provider, model and base URL are ordinary settings; the key is encrypted at rest and never shown again.

With none configured, Prodpeek makes zero outbound AI calls and loses no functionality.

Extra request headers¶

Not an environment variable — they are per service, set on the add-service form or through the API, and encrypted at rest like the credential.

For upstreams that need more than a token: Grafana Cloud's hosted MCP wants X-Grafana-URL to say which stack a call is for.

Refused, always: Authorization and Proxy-Authorization (the credential owns those), Host (it redirects a stored credential at a different server), and the hop-by-hop headers Connection, Transfer-Encoding, Upgrade, Content-Length, TE and Trailer. A value containing a newline is refused as header injection.

Logging¶

	Default
`PRODPEEK_LOG_LEVEL`	`info`	`warning` shows only refusals and errors
`PRODPEEK_ACCESS_LOG`	`false`	uvicorn's raw request lines. The decision log is the useful signal

One readable line per decision:
