Tiny utility for converting time durations between human-readable strings and milliseconds. Converts '2 days', '1h', '10m', '30s', '100ms' to millisecond values and vice versa. Zero dependencies, tiny (< 1KB). Used everywhere JWT expiration ('7d' → 604800000), cache TTL configuration, setTimeout/setInterval helpers, and any code that needs human-readable time duration strings. Maintained by Vercel.

Context Optimizer MCP server providing AI agents with tools to optimize and compress their context window — summarizing long documents, chunking content for efficient retrieval, ranking context by relevance, removing redundant information, and managing token budgets. Helps agents work efficiently within LLM context limits by intelligently compressing and prioritizing what information enters the context.

MCP server for Kong — the leading open-source API gateway and API management platform. Enables AI agents to manage Kong services, routes, plugins, consumers, and API policies. Agents can configure rate limiting, authentication, load balancing, and traffic management across Kong-managed APIs.

Personal MCP server by Lucas Montano (Brazilian tech YouTuber/developer with large following). A showcase and educational MCP server demonstrating MCP server implementation patterns — includes tools for fetching YouTube channel data, displaying developer profile information, and serving as a reference implementation for developers learning to build MCP servers.

OSINT Tools MCP server enabling AI security agents to perform open-source intelligence gathering — querying Shodan for exposed services, VirusTotal for threat indicators, WHOIS lookups, DNS reconnaissance, and integrating multiple OSINT data sources into agent-driven threat research and security assessment workflows.

Extremely fast Python linter and formatter written in Rust. Ruff replaces Flake8, isort, pyupgrade, pydocstyle, and many other Python linting tools with a single, blazing-fast binary. 10-100x faster than equivalent Python linters. Ruff implements 800+ lint rules and includes an auto-formatter compatible with Black. The modern standard for Python code quality tooling.

Cross-platform ANSI color codes for Python terminal output — makes ANSI escape codes work on Windows and provides simple color constants. colorama features: colorama.init() for Windows ANSI support, Fore.RED/GREEN/BLUE/etc for text colors, Back.RED/GREEN/BLUE/etc for background colors, Style.BRIGHT/DIM/RESET_ALL for formatting, autoreset=True to auto-reset after each print, strip=True to remove ANSI on non-TTY, convert=True for Windows translation, and cross-platform compatibility. Works transparently alongside other libraries that output ANSI codes (rich, loguru).

Fast data validation and settings management library using Python type annotations — defines data models as classes, validates on instantiation, serializes to/from JSON. pydantic v2 features: BaseModel with field type hints, Field() for constraints/defaults/aliases, model.model_validate() for dict input, model.model_dump() for serialization, model_json_schema() for JSON Schema, @field_validator and @model_validator decorators, discriminated unions, generics, computed_field, ConfigDict for model config, BaseSettings for env var loading, Annotated types, strict mode, and Rust-backed core for 5-50x v1 speedup.

Extremely fast Python linter and formatter — Rust-based tool that replaces flake8, pylint, isort, pyupgrade, and black in a single tool. ruff features: 800+ built-in lint rules (flake8, pylint, pycodestyle, pydocstyle, pyflakes, isort equivalents), --fix for auto-fixing many violations, format sub-command (black-compatible formatter), select/ignore for rule configuration, per-file-ignores, extend-select for enabling rule categories, ruff check --watch for continuous linting, Python 3.8-3.13 support, pyproject.toml configuration, line-length, target-version, and VS Code extension. 10-100x faster than flake8+isort+black.

Python package for creating beautiful command-line interfaces using decorators. Created by Armin Ronacher (Flask). Define CLI commands with @click.command(), arguments with @click.argument(), and options with @click.option(). Supports command groups, nested subcommands, auto-generated help text, shell completion, and rich prompt/confirmation utilities. The standard CLI framework for Python web tool authors.

Google's core Java libraries — utilities that fill gaps in the Java standard library. Key components: Immutable collections (ImmutableList, ImmutableMap, ImmutableSet — truly immutable, not unmodifiable views), Multimap/Multiset/Table (missing JDK collection types), LoadingCache (in-memory cache with expiry and loading function), Optional (predates Java 8's Optional, still widely used), Preconditions (argument validation), Strings utilities, EventBus (pub/sub within JVM process), RateLimiter (token bucket rate limiting), and functional idioms (Function, Predicate before Java 8 lambdas were standard). Caffeine Cache largely supersedes Guava Cache for new projects.
