Model Context Protocol server for semantic passage re-ranking and cross-encoder relevance scoring across complex RAG contexts.

The fastest inference engine for Qwen3.8-27B on the NVIDIA RTX 5090: up to 500 tokens/s for one agent and up to 2,000 tokens/s for many, contexts up to 1M tokens, and a launcher that shows what every setting costs. Windows and Linux.

Arkon: Enterprise AI Knowledge Hub & MCP Server. Self-hosted knowledge base for teams to manage RAG contexts, access policies, and AI skills. Connect Claude and other LLMs via Model Context Protocol (MCP) for automated, secure organizational knowledge integration.

claude-red is a curated library of offensive security skills designed for the Claude skills system. Each skill is a structured SKILL.md file that primes Claude with expert-level methodology for a specific attack surface — from SQLi to shellcode, EDR evasion to exploit development.

Context window optimization for AI coding agents. Sandboxes tool output (98% reduction), persists session memory, and enforces routing across 17 platforms via MCP + hooks.

Build your own network of agents from Claude Code, Codex and Pi: persistent teams with roles, shared context and owned work.

Persistent Context Across Sessions for Every Agent – Captures everything your agent does during sessions, compresses it with AI, and injects relevant context back into future sessions. Works with Claude Code, OpenClaw, Codex, Gemini, Hermes, Copilot, OpenCode + More

The definitive reference and prompt library for mastering Claude Code: context management, subagent workflows, and terminal automation.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Never stop coding. Free MIT AI gateway: one endpoint, 375 providers (150+ free), 1,400+ models Kimi, Claude, GPT, Gemini, GLM, DeepSeek, MiniMax. Works with Claude Code, Codex, Cursor, OpenCode, Cline & Copilot. Quota-aware auto-fallback, RTK+Caveman compression saves 15-95% tokens, MCP/A2A, Desktop/PWA. Built by 900+ contributors

Model Context Protocol (MCP) server providing AI agents with live LinkedIn integration: search jobs, scrape target company profiles, extract job requirements, and fetch personalized job recommendations.

Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.

Official Brave Search Model Context Protocol server enabling AI assistants to perform web, local, and news searches with privacy preservation.

Persistent Context Across Sessions for Every Agent – Captures everything your agent does during sessions, compresses it with AI, and injects relevant context back into future sessions. Works with Claude Code, OpenClaw, Codex, Gemini, Hermes, Copilot, OpenCode + More

Free, local plugin that keeps tool output out of your coding agent's context window. Sandbox and SQLite FTS5 search, 99% fewer bytes in context. Works with Claude Code, Codex, Pi, OpenCode, Gemini CLI, Copilot CLI and 4 more agents. Zero telemetry.

Upstash Context7 MCP Server providing ultra-fast vector search, semantic context retrieval, and Redis caching for AI models and Cursor IDE.

High-performance solution in Rust for long-term memory for agent coding CLIs and to facilitate seamless handoff and context preservation between different agent vendors.

Official Model Context Protocol server for Chroma, exposing semantic embeddings search, vector collection management, and document querying.

The first open-source harness builder for AI coding. Make AI coding deterministic, repeatable, and resilient to context drift.

Model Context Protocol server providing vector similarity search and payload filtering across Qdrant vector databases.

Model Context Protocol server retrieving stack traces, error issues, and debug breadcrumbs from Sentry for automated bug fixing.

Model Context Protocol server for searching, reading, and extracting content from Google Drive documents and spreadsheets.

Model Context Protocol reference server providing secure, read-only and analytical schema exploration and SQL query execution against PostgreSQL databases.
