Rlg MCP

Near-lock-free structured logging for Rust, plus an ecosystem of companion crates: CLI tooling, MCP server, OTLP exporter, tower middleware, WebAssembly bindings, PII redaction, test utilities, and aggregation reports. Its 3 documented tools cluster into tail, filter, summarize.

People who work with logging, observability and otlp and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as container (OCI image) - can be sandboxed away from your filesystem

license Apache-2.0 - declared in the repository

registry namespace io.github.sebastienrousseau is GitHub-verified and matches the repo owner

The 3 tools it gives your agent

Extracted from the project's README - what rlg-mcp lets an agent do.

tail_log: - path, optional n (default 100) → last n parseable records, rendered in Logfmt.
filter_log: - path, optional min_level / component / format → records matching every supplied filter, in the chosen LogFormat.
summarize_errors: - path → JSON map of component → error_count for ERROR-and-above records.
