Pare Lint tools (7, 4 write)
write = sends, deletes, buys or postsRead from the package source without running it. The installed server may list more.
biome-checkwrite actionRuns Biome check (lint + format) and returns structured diagnostics (file, line, rule, severity, message). Use instead of running `biome check` in the terminal.
biome-formatFormats files with Biome (format --write) and returns a structured list of changed files. Use instead of running `biome format --write` in the terminal.
format-checkChecks if files are formatted and returns a structured list of files needing formatting. Use instead of running `prettier --check` in the terminal.
lintwrite actionRuns ESLint and returns structured diagnostics (file, line, rule, severity, message). Use instead of running `eslint` in the terminal.
oxlintwrite actionRuns Oxlint and returns structured diagnostics (file, line, rule, severity, message). Use instead of running `oxlint` in the terminal.
prettier-formatFormats files with Prettier (--write) and returns a structured list of changed files. Use instead of running `prettier --write` in the terminal.
stylelintwrite actionRuns Stylelint and returns structured diagnostics (file, line, rule, severity, message). Use instead of running `stylelint` in the terminal.

Pare
Reliable, structured CLI output for AI agents — no more parsing fragile terminal text.
Pare provides MCP servers that wrap common developer tools (git, npm, docker, test runners, etc.) and return clean, schema-validated JSON instead of raw terminal text. Agents get typed data they can act on directly, without brittle string parsing.
The Problem
Parsing CLI output is fragile. Raw terminal text includes ANSI escape codes, decorative headers, progress bars, locale-specific formatting, and platform differences that break agent workflows in subtle ways. An agent that works fine with git status on macOS may fail on Windows because the output format changed. A test runner's summary line might shift between versions, silently breaking a regex.
Pare eliminates this entire class of errors by returning schema-validated JSON with consistent field names, regardless of platform, tool version, or locale. As a bonus, structured output is significantly smaller — agents use fewer tokens per tool call:
Token estimates use ~4 chars/token. The biggest savings appear on verbose commands (builds, installs, tests). For simpler tools like eslint or tsc, the main advantage is reliable structured data — agents can use typed JSON directly rather than parsing strings.
How It Works
Each Pare tool returns two outputs:
- content — human-readable text, for MCP clients that display it
- structuredContent — typed, schema-validated JSON, ready for agents to process
This uses MCP's structuredContent and outputSchema features to provide type-safe, validated data that agents can rely on without custom parsing.
Example: git status
