Configuration

CC-Relay is configured via YAML or TOML files. This guide covers all configuration options.

Configuration File Location

Default locations (checked in order):

./config.yaml or ./config.toml (current directory)
~/.config/cc-relay/config.yaml or ~/.config/cc-relay/config.toml
Path specified via --config flag

The format is automatically detected from the file extension (.yaml, .yml, or .toml).

Generate a default config with:

cc-relay config init

Environment Variable Expansion

CC-Relay supports environment variable expansion using ${VAR_NAME} syntax in both YAML and TOML formats:

providers:
- name: "anthropic"
  type: "anthropic"
  keys:
    - key: "${ANTHROPIC_API_KEY}"  # Expanded at load time

[[providers]]
name = "anthropic"
type = "anthropic"

[[providers.keys]]
key = "${ANTHROPIC_API_KEY}"  # Expanded at load time

Server Configuration

Listen Address

The listen field specifies where the proxy listens for incoming requests:

server:
listen: "127.0.0.1:8787"  # Local only (recommended)
# listen: "0.0.0.0:8787"  # All interfaces (use with caution)

[server]
listen = "127.0.0.1:8787"  # Local only (recommended)
# listen = "0.0.0.0:8787"  # All interfaces (use with caution)

Authentication

CC-Relay supports multiple authentication methods:

API Key Authentication

Require clients to provide a specific API key:

server:
auth:
  api_key: "${PROXY_API_KEY}"

[server.auth]
api_key = "${PROXY_API_KEY}"

Clients must include the header: x-api-key: <your-proxy-key>

Claude Code Subscription Passthrough

Allow Claude Code subscription users to connect:

server:
auth:
  allow_subscription: true

[server.auth]
allow_subscription = true

This accepts Authorization: Bearer tokens from Claude Code.

Combined Authentication

Allow both API key and subscription authentication:

server:
auth:
  api_key: "${PROXY_API_KEY}"
  allow_subscription: true

[server.auth]
api_key = "${PROXY_API_KEY}"
allow_subscription = true

No Authentication

To disable authentication (not recommended for production):

server:
auth: {}
# Or simply omit the auth section

# Simply omit the [server.auth] section
# or define an empty section:
[server.auth]

HTTP/2 Support

Enable HTTP/2 for better performance with concurrent requests:

server:
enable_http2: true

[server]
enable_http2 = true

Transparent Authentication

cc-relay automatically detects how to handle authentication based on what the client sends:

How It Works

Client Sends	cc-relay Behavior	Use Case
`Authorization: Bearer <token>`	Forward unchanged	Claude Code subscription users
`x-api-key: <key>`	Forward unchanged	Direct API key users
No auth headers	Use configured provider keys	Enterprise/team deployments

Claude Code Subscription Users

If you have a Claude Code subscription (Max/Team/Enterprise plan), you can use cc-relay as a transparent proxy:

# Set cc-relay as your API endpoint
export ANTHROPIC_BASE_URL="http://localhost:8787"

# Your subscription token flows through unchanged
# ANTHROPIC_AUTH_TOKEN is already set by Claude Code
claude

No API key required - cc-relay forwards your subscription token to Anthropic.

Enterprise/Team Deployments

For centralized API key management, don’t provide client auth - cc-relay uses configured keys:

# config.yaml
providers:
- name: anthropic
  type: anthropic
  base_url: https://api.anthropic.com
  enabled: true
  keys:
    - key: ${ANTHROPIC_API_KEY}
      rpm_limit: 50

# config.toml
[[providers]]
name = "anthropic"
type = "anthropic"
base_url = "https://api.anthropic.com"
enabled = true

[[providers.keys]]
key = "${ANTHROPIC_API_KEY}"
rpm_limit = 50

# Client has no auth - uses configured keys
export ANTHROPIC_BASE_URL="http://localhost:8787"
unset ANTHROPIC_AUTH_TOKEN
unset ANTHROPIC_API_KEY
claude

Mixed Mode

You can run both modes simultaneously:

Subscription users: Their auth flows through (no key pool overhead)
Team users: Use configured keys with rate limit pooling

Rate limiting and key pooling only apply when using configured keys, not client-provided auth.

Key Points

Auto-detection: No configuration needed - behavior determined by client headers
Subscription passthrough: Authorization: Bearer forwarded unchanged
Fallback keys: Used only when client has no auth
Key pool efficiency: Only tracks usage of YOUR keys, not client subscriptions

Provider Configuration

Provider Types

CC-Relay currently supports two provider types:

Type	Description	Default Base URL

      rpm_limit: 60
      tpm_limit: 100000

[[providers]]
name = "anthropic"
type = "anthropic"
enabled = true

[[providers.keys]]
key = "${ANTHROPIC_API_KEY_1}"
rpm_limit = 60
tpm_limit = 100000

[[providers.keys]]
key = "${ANTHROPIC_API_KEY_2}"
rpm_limit = 60
tpm_limit = 100000

[[providers.keys]]
key = "${ANTHROPIC_API_KEY_3}"
rpm_limit = 60
tpm_limit = 100000

Custom Base URL

Override the default API endpoint:

providers:
- name: "anthropic-custom"
  type: "anthropic"
  base_url: "https://custom-endpoint.example.com"

[[providers]]
name = "anthropic-custom"
type = "anthropic"
base_url = "https://custom-endpoint.example.com"

Logging Configuration

Log Levels

Level	Description
`debug`	Verbose output for development
`info`	Normal operation messages
`warn`	Warning messages
`error`	Error messages only

Log Format

logging:
format: "text"   # Human-readable (default)
# format: "json" # Machine-readable, for log aggregation

[logging]
format = "text"   # Human-readable (default)
# format = "json" # Machine-readable, for log aggregation

Debug Options

Fine-grained control over debug logging:

logging:
level: "debug"
debug_options:
  log_request_body: true      # Log request bodies (redacted)
  log_response_headers: true  # Log response headers
  log_tls_metrics: true       # Log TLS connection info
  max_body_log_size: 1000     # Max bytes to log from bodies

[logging]
level = "debug"

[logging.debug_options]
log_request_body = true      # Log request bodies (redacted)
log_response_headers = true  # Log response headers
log_tls_metrics = true       # Log TLS connection info
max_body_log_size = 1000     # Max bytes to log from bodies

Cache Configuration

CC-Relay provides a unified caching layer with multiple backend options for different deployment scenarios.

Cache Modes

Mode	Backend	Use Case
`single`	Ristretto	Single-instance deployments, high performance
`ha`	Olric	Multi-instance deployments, shared state
`disabled`	Noop	No caching, passthrough

Single Mode (Ristretto)

Ristretto is a high-performance, concurrent in-memory cache. This is the default mode for single-instance deployments.

cache:
mode: single
ristretto:
  num_counters: 1000000  # 10x expected max items
  max_cost: 104857600    # 100 MB
  buffer_items: 64       # Admission buffer size

[cache]
mode = "single"

[cache.ristretto]
num_counters = 1000000  # 10x expected max items
max_cost = 104857600    # 100 MB
buffer_items = 64       # Admission buffer size

Field	Type	Default	Description
`num_counters`	int64	1,000,000	Number of 4-bit access counters. Recommended: 10x expected max items.
`max_cost`	int64	104,857,600 (100 MB)	Maximum memory in bytes the cache can hold.
`buffer_items`	int64	64	Number of keys per Get buffer. Controls admission buffer size.

HA Mode (Olric) - Embedded

For multi-instance deployments requiring shared cache state, use embedded Olric mode where each cc-relay instance runs an Olric node.

cache:
mode: ha
olric:
  embedded: true
  bind_addr: "0.0.0.0:3320"
  dmap_name: "cc-relay"
  environment: lan
  peers:
    - "other-node:3322"  # Memberlist port = bind_addr + 2
  replica_count: 2
  read_quorum: 1
  write_quorum: 1
  member_count_quorum: 2
  leave_timeout: 5s

[cache]
mode = "ha"

[cache.olric]
embedded = true
bind_addr = "0.0.0.0:3320"
dmap_name = "cc-relay"
environment = "lan"
peers = ["other-node:3322"]  # Memberlist port = bind_addr + 2
replica_count = 2
read_quorum = 1
write_quorum = 1
member_count_quorum = 2
leave_timeout = "5s"

Field	Type	Default	Description
`embedded`	bool	false	Run embedded Olric node (true) vs. connect to external cluster (false).
`bind_addr`	string	required	Address for Olric client connections (e.g., “0.0.0.0:3320”).
`dmap_name`	string	“cc-relay”	Name of the distributed map. All nodes must use the same name.
`environment`	string	“local”	Memberlist preset: “local”, “lan”, or “wan”.
`peers`	[]string	-	Memberlist addresses for peer discovery. Uses port bind_addr + 2.
`replica_count`	int	1	Number of copies per key. 1 = no replication.
`read_quorum`	int	1	Minimum successful reads for response.
`write_quorum`	int	1	Minimum successful writes for response.
`member_count_quorum`	int32	1	Minimum cluster members required to operate.
`leave_timeout`	duration	5s	Time to broadcast leave message before shutdown.

Important: Olric uses two ports - the bind_addr port for client connections and bind_addr + 2 for memberlist gossip. Ensure both ports are open in your firewall.

HA Mode (Olric) - Client Mode

Connect to an external Olric cluster instead of running embedded nodes:

cache:
mode: ha
olric:
  embedded: false
  addresses:
    - "olric-node-1:3320"
    - "olric-node-2:3320"
  dmap_name: "cc-relay"

[cache]
mode = "ha"

[cache.olric]
embedded = false
addresses = ["olric-node-1:3320", "olric-node-2:3320"]
dmap_name = "cc-relay"

Field	Type	Description
`embedded`	bool	Set to `false` for client mode.
`addresses`	[]string	External Olric cluster addresses.
`dmap_name`	string	Distributed map name (must match cluster configuration).

Disabled Mode

Disable caching entirely for debugging or when caching is handled elsewhere:

cache:
mode: disabled

[cache]
mode = "disabled"

For detailed cache configuration including cache key conventions, cache busting strategies, HA clustering guides, and troubleshooting, see the Cache System documentation.

Routing Configuration

CC-Relay supports multiple routing strategies for distributing requests across providers.

# ==========================================================================
# Routing Configuration
# ==========================================================================
routing:
# Strategy: round_robin, weighted_round_robin, shuffle, failover (default)
strategy: failover

# Timeout for failover attempts in milliseconds (default: 5000)
failover_timeout: 5000

# Enable debug headers (X-CC-Relay-Strategy, X-CC-Relay-Provider)
debug: false

# ==========================================================================
# Routing Configuration
# ==========================================================================
[routing]
# Strategy: round_robin, weighted_round_robin, shuffle, failover (default)
strategy = "failover"

# Timeout for failover attempts in milliseconds (default: 5000)
failover_timeout = 5000

# Enable debug headers (X-CC-Relay-Strategy, X-CC-Relay-Provider)
debug = false

Routing Strategies

Strategy	Description
`failover`	Try providers in priority order, fallback on failure (default)
`round_robin`	Sequential rotation through providers
`weighted_round_robin`	Distribute proportionally by weight
`shuffle`	Fair random distribution

Provider Weight and Priority

Weight and priority are configured in the provider’s first key:

providers:
- name: "anthropic"
  type: "anthropic"
  keys:
    - key: "${ANTHROPIC_API_KEY}"
      weight: 3      # For weighted-round-robin (higher = more traffic)
      priority: 2    # For failover (higher = tried first)

[[providers]]
name = "anthropic"
type = "anthropic"

[[providers.keys]]
key = "${ANTHROPIC_API_KEY}"
weight = 3      # For weighted-round-robin (higher = more traffic)
priority = 2    # For failover (higher = tried first)

For detailed routing configuration including strategy explanations, debug headers, and failover triggers, see the Routing documentation.

Validating Configuration

Validate your configuration file:

cc-relay config validate

Tip: Always validate configuration changes before deploying. Hot-reload will reject invalid configurations, but validation catches errors before they reach production.

Hot Reloading

CC-Relay automatically detects and applies configuration changes without requiring a restart. This enables zero-downtime configuration updates.

How It Works

CC-Relay uses fsnotify to monitor the config file for changes:

File watching: The parent directory is monitored to properly detect atomic writes (temp file + rename pattern used by most editors)
Debouncing: Multiple rapid file events are coalesced with a 100ms debounce delay to handle editor save behavior
Atomic swap: New configuration is loaded and swapped atomically using Go’s sync/atomic.Pointer
In-flight preservation: Requests in progress continue with the old configuration; new requests use the updated configuration

Events That Trigger Reload

Event	Triggers Reload
File write	Yes
File create (atomic rename)	Yes
File chmod	No (ignored)
Other file in directory	No (ignored)

Logging

When hot-reload occurs, you’ll see log messages:

INF config file reloaded path=/path/to/config.yaml
INF config hot-reloaded successfully

If the new configuration is invalid:

ERR failed to reload config path=/path/to/config.yaml error="validation error"

Invalid configurations are rejected and the proxy continues with the previous valid configuration.

Limitations

Listen address: Changing server.listen requires a restart
gRPC address: Changing grpc.listen requires a restart

Configuration options that can be hot-reloaded:

Logging level and format
Routing strategy, failover timeout, weights, and priorities
Provider enable/disable, base URL, and model mapping
Keypool strategy, key weights, and per-key limits
Max concurrent requests and max body size
Health check intervals and circuit breaker thresholds

Hot-reload guarantees

New requests use the latest configuration after reload completes.
In-flight requests continue with the previous configuration.
Reload applies atomically to routing/provider/keypool state.
Invalid configs are rejected and the previous config remains active.
