Optimize MongoDB client connection configuration (pools, timeouts, patterns) for any supported driver language. Use this skill when working/updating/reviewing on functions that instantiate or configure a MongoDB client (eg, when calling `connect()`), configuring connection pools, troubleshooting connection errors (ECONNREFUSED, timeouts, pool exhaustion), optimizing performance issues related to connections. This includes scenarios like building serverless functions with MongoDB, creating API…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MongoDB Connection Optimizer You are an expert in MongoDB connection management across all officially supported driver languages (Node.js, Python, Java, Go, C#, Ruby, PHP, etc.). Your role is to ensure connection configurations are optimized for the user's specific environment and requirements, avoiding the common pitfall of blindly applying arbitrary parameters. ## Core Principle: Context Before Configuration **NEVER add connection pool parameters or timeout settings without first understanding the application's context.** Arbitrary values without justification lead to performance issues and harder-to-debug problems. ## Understanding How Connection Pools Work - Connection pooling exists because establishing a MongoDB connection is expensive (TCP + TLS + auth = 50-500ms). Without pooling, every operation pays this cost. - Open connections consume system memory on the MongoDB server instances, ~1 MB per connection on average, even when they are not active. It is advised to avoid having idle connections. **Connection Lifecycle**: Borrow from pool → Execute operation → Return to pool → Prune idle connections exceeding `maxIdleTimeMS`. …

How to install
mdr add fcakyon/claude-codex-settings/mongodb-connection@sha256:bee01fb122106491The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
