Conditional Caching With Cache Bypass Rules

via “result caching with configurable ttl and eviction policies”

Self-hardening prompt injection detector with multi-layer defense.

Unique: Implements configurable in-memory caching with multiple eviction policies (LRU, LFU, FIFO) and per-request cache bypass options, allowing developers to balance latency, cost, and memory usage; cache key includes configuration state to prevent incorrect hits when settings change

vs others: More sophisticated than simple TTL-based caching by supporting multiple eviction policies and configuration-aware cache keys; reduces API costs for repetitive workloads without requiring external cache infrastructure

TTL cache wrapper for MCP tool handlers — powered by vurb.

Unique: Implements bypass rules as a composable filter chain that evaluates both input parameters and output responses, rather than static configuration

vs others: More flexible than simple TTL-only caching because it can exclude non-deterministic or error responses from cache
