It can present local statistics, upload them to Splitrail Cloud for cross-machine aggregation, and expose statistics through an MCP server. ### Project history Piebald AI created the public repository in 2025 and published v1.0.0 in August of that year. The project subsequently broadened its analyzers across Claude Code, Codex CLI, Gemini CLI and Qwen Code, Cline-derived tools, GitHub Copilot, OpenCode, Pi Agent, and related coding-agent environments. ### Adoption history Splitrail is distributed as release binaries and through Homebrew. Its optional cloud companion adds private account storage, cross-machine aggregation, and leaderboard features without replacing the local CLI workflow. ### How it is used Running `splitrail` reviews discovered coding-agent usage. `splitrail mcp` starts an MCP server with tools for daily statistics, model usage, costs, file operations, and comparisons; cloud upload is configured with an API token and upload preferences in `~/.splitrail.toml`. ### Why package nerds care Splitrail reflects the emergence of a new CLI observability niche around AI-assisted development: one local binary normalizes usage records from otherwise separate agent ecosystems and can expose the aggregate through MCP. ### Timeline - 2025: Official repository created. - 2025: v1.0.0 published. - 2026: Splitrail documented broad multi-agent support, cloud aggregation, and an MCP server. ### Related projects - Splitrail Cloud is the optional hosted companion for synchronization and aggregation. - Piebald is the agentic developer product from the same team. ### Sources - - - - source_facts.package-manager.brew ## Security Notes No matching local secret-handling manifest was found for splitrail.
