Server-wide configuration.

Fields

api_token: String

Static Bearer token for API authentication (NOTEDTHAT_API_TOKEN).

kbs: BTreeMap<String, KbSlug>

Declared knowledge bases, as a sorted map of slug string → KbSlug.

tenant_slug: TenantSlug

Tenant slug — hardcoded to "default" per Metis directive.

listen_addr: SocketAddr

Socket address the HTTP server binds to (NOTEDTHAT_LISTEN_ADDR; default 0.0.0.0:8080).

storage: StorageConfig

The selected storage backend and its configuration (NOTEDTHAT_STORAGE_BACKEND; default s3).

events: EventsConfig

The selected object change event log and its configuration (NOTEDTHAT_EVENTS_BACKEND; default none).

log_format: LogFormat

Log output format (NOTEDTHAT_LOG_FORMAT; pretty or json).

qdrant: ServerQdrantConfig

Qdrant client configuration.

embedder: EmbedderConfig

Embedder configuration.

webdav_username: String

WebDAV Basic authentication username (NOTEDTHAT_WEBDAV_USERNAME; required).

webdav_password: String

WebDAV Basic authentication password (NOTEDTHAT_WEBDAV_PASSWORD; required).

mcp_http_allowed_origins: Vec<String>

Allowed origins for MCP HTTP CORS (NOTEDTHAT_MCP_HTTP_ALLOWED_ORIGINS; empty → ["null"]).

mcp_http_allowed_hosts: Vec<String>

Allowed hosts for MCP HTTP Host header validation (NOTEDTHAT_MCP_HTTP_ALLOWED_HOSTS; empty → ["127.0.0.1", "localhost", "::1"]).

mcp_anonymous: McpAnonymous

Whether /mcp admits anonymous callers (NOTEDTHAT_MCP_ANONYMOUS; default auto).

max_patchable_size: u64

Maximum patchable object size in bytes (NOTEDTHAT_MAX_PATCHABLE_SIZE; default 100 MiB).

mcp_max_read_bytes: u64

Most bytes one MCP object read may fetch (NOTEDTHAT_MCP_MAX_READ_BYTES; default 16 MiB, the API body cap). Larger objects are read in slices.

mcp_max_sessions: usize

Most MCP sessions this process holds at once (NOTEDTHAT_MCP_MAX_SESSIONS; default 256). An initialize past the bound is refused 503 with Retry-After: 5 (D38).

ready_probe_interval_ms: u64

How often /readyz’s poller probes the storage backend and Qdrant, in milliseconds; also each probe’s deadline (NOTEDTHAT_READY_PROBE_INTERVAL_MS; default 5000).

metrics_listen_addr: Option<SocketAddr>

Where the Prometheus exposition is served, or None while metrics are off (NOTEDTHAT_METRICS_ENABLED, NOTEDTHAT_METRICS_LISTEN_ADDR; D69).

One field rather than a flag beside an address, so “enabled, and here” and “off” are the only two states anything downstream can see. The pair of settings is reconciled once, in Self::from_cli; an address supplied while the feature is off refuses startup rather than arriving here as a value nobody reads.

staging: StagingConfig

Shared private staging directory for uploads and index snapshots (NOTEDTHAT_UPLOAD_TMP_DIR).

oidc: Option<OidcSettings>

Identity-provider settings (NOTEDTHAT_OIDC_*); None when no issuer is set.

Implementations

impl Config

pub fn from_env() -> Result<Self, Error>

Parse configuration from the environment alone.

Equivalent to Config::from_cli over an empty argv, which is what a container that passes no arguments gets.

Errors

As Config::from_cli, plus Err(Error::Config { .. }) if a variable holds a value the parser cannot accept at all.

pub fn from_cli(cli: ServerCli) -> Result<Self, Error>

Validate the settings this run supplied, from either source.

Errors

Returns Err(Error::Config { .. }) if any required setting is missing, if any value is invalid (empty token, bad slug, duplicate slug, etc.), or if any [REMOVED_LISTENER_ENV_VARS] entry was supplied.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
