Rlg Mcp

Near-lock-free structured logging for Rust: records leave the application thread with a few atomic operations and are formatted and written by a background flusher.

Contents

Getting started

• Install — Cargo for the libraries, cargo install for the CLIs and the MCP server
• Requirements — toolchain floor, platforms
• Quick Start — one structured record, fired and flushed

Install

As a Rust library

[dependencies]
rlg = "0.0.15"

Satellites install the same way, all at the same version:

[dependencies]
rlg-otlp   = "0.0.15"  # ship records to an OpenTelemetry Collector
rlg-tower  = "0.0.15"  # per-request access logs for tower services
rlg-redact = "0.0.15"  # scrub secrets and PII before they are written

[dev-dependencies]
rlg-test   = "0.0.15"  # assert on captured records in tests

Command-line tools

cargo install rlg-cli      # `rlg`: filter and convert log files
cargo install rlg-report   # `rlg-report`: summaries by level, component and message
cargo install rlg-mcp      # `rlg-mcp`: log files as tools for AI agents
