Struct CacheBackendConfig 

pub struct CacheBackendConfig {
    pub backend: String,
    pub url: Option<String>,
    pub prefix: String,
}

Global cache backend configuration.

Controls which storage backend is used for response caching. Per-backend TTL and max_entries settings remain the same regardless of backend.

Backends

• "memory" (default): In-process cache using moka. Fast, no external deps, but not shared across proxy instances.
• "redis": External Redis cache. Shared across instances. Requires the redis-cache feature.
• "sqlite": Local SQLite cache. Persistent across restarts. Requires the sqlite-cache feature.

Fields

backend: String

Cache backend type: “memory” (default), “redis”, or “sqlite”.

url: Option<String>

Connection URL for external backends (Redis or SQLite path).

prefix: String

Key prefix for external cache entries (default: “mcp-proxy:”).
