15 #prompt-engineering MCP Servers & Clients

MCP Gateway

IBM

An AI Gateway, registry, and proxy that sits in front of any MCP, A2A, or REST/gRPC APIs, exposing a unified endpoint with centralized discovery, guardrails and management. Optimizes Agent & Tool calling, and supports plugins.

ctx: The missing link between your codebase and your LLM. Context as Code (CaC) tool with MCP server inside.

context-hub

CTX: a tool that solves the context management gap when working with LLMs like ChatGPT or Claude. It helps developers organize and automatically collect information from their codebase into structured documents that can be easily shared with AI assistants.

Prompt Decorators

synaptiai

A standardized framework for enhancing how LLMs process and respond to prompts through composable decorators, featuring an official open standard specification and Python reference implementation. Claude Code plugin and MCP server integration.

seonglae

Global Notion workspace-accessible MCP server for all Notion pages within the workspace

Prompt Enhancer MCP - Optimize, Analyze & Convert AI Prompts

yedanyagamiai-cmd

49 AI tools across 9 MCP servers. Enterprise AGI Runtime (1,054 tests). Free tier. ☕ buymeacoffee.com/yesinyagami

Pqs Prompt Quality Score

OnChainAIIntel

The world's first named AI prompt quality score. Score any LLM prompt before it hits any model — returns grade (A-F), score out of 40, percentile, and dimension breakdown across 8 quality dimensions.

LLM persona consistency engine — enforce JSON personality and style constraints across interactions. Prevents persona drift with 160,000 deductively-derived behavioral rules.

🐢 Lazy Terminal

Heterohabilis

An LLM-based smart terminal for lazy guys :P

Documentation and assembly review for @nhtio/adk.

Gelbooru Mcp

citronlegacy

A Python MCP server that wraps the Gelbooru API. Connect it to any MCP-compatible client (Claude Desktop, Cursor, etc.) to search posts, look up tags, and generate Stable Diffusion prompts from real character appearance data — all directly from your AI assistant.

Prompt Gen Mcp

prompt-gen-mcp

Transform simple questions into comprehensive, context-aware prompts

AI-powered prompt refinement tool with adaptive questioning and multi-provider support. Provides 5 MCP tools (refine_prompt, tweak_prompt, list_models, list_providers, validate_environment) for intelligent prompt engineering. Supports Google Gemini, Anthropic Claude, OpenAI, Groq

Promptibus Mcp

promptibus

Model intelligence for AI agents — syntax, parameters, pricing, and routing for 67+ generative AI models (Midjourney, Flux, Suno, Runway, DALL-E, Stable Diffusion). 7 tools that let any MCP client recommend, compare, optimize, and price AI model calls.

🤖 Large Language Models (LLMs)

RahulSaini02

This repo is dedicated to learning and working with large language models (LLMs), prompt engineering, and modern GenAI tools such as LangChain, RAG, and vector databases.
