A production-ready knowledge graph system for software engineering that connects design patterns, refactoring techniques, and software laws through semantic relationships. Built for AI agents first — integrate software engineering expertise directly into Claude Code, Cursor, and other MCP-compatible tools.

passive-aggression MCP — wraps StupidAPIs (keyless — no credential needed)

Enables AI tools to create and edit Font Proof documents for type designers, supporting PDF font proofs and live-reload from Glyphs.app.

MCP server for satellite TLE tracking data

Provides complete access to Model Context Protocol documentation through an MCP server, allowing LLMs to query specific sections like 'Tools', 'Resources', and 'Authorization' to retrieve comprehensive protocol specifications.

Python and R client libraries built from OpenAPI JSON spec from Data Catalog API

An MCP server that recreates Microsoft Comic Chat (1996) to generate comic strips from conversation summaries, using original character art and deterministic layout, with no LLM calls.

Enables AI assistants to read a user's personal AI-written news briefing and adjust its sources, topics, and settings through natural language, including tuning topic preferences, requesting deep dives, and managing subscriptions.

The Chronulus MCP Server enables Claude to interact with Chronulus AI's forecasting and prediction agents, allowing users to analyze time series data and generate forecasts through natural language. Developed by Chronulus AI, this implementation is built using Python and integrates with the Chronulus API to provide specialized time series forecasting capabilities. The server can be deployed using pip, Docker, or uvx, and requires a Chronulus API key for authentication. It's particularly useful for users who need to perform time series analysis, generate predictions, and visualize forecasting data directly within their Claude conversations.

A minimal FastAPI-based MCP server that provides a tool for calculating Body Mass Index (BMI) using SSE for discovery. It serves as a template for developers to build and deploy lightweight MCP services on platforms like Render.

Systemctl MCP Server provides a bridge between Claude and systemd services, allowing direct management of system services through the conversation interface. The implementation exposes tools for checking service status, starting, stopping, and restarting systemd services via a FastMCP server that communicates using Server-Sent Events (SSE). Built by Karim Lalani, it leverages pystemd to interact with the systemd daemon and includes both server and client components for flexible deployment. This tool is particularly valuable for system administrators who need to monitor and control system services without leaving their AI assistant conversation or switching to a terminal.

This ComfyUI MCP server integrates the ComfyUI stable diffusion interface with AI assistants. It provides a streamlined API for generating images using ComfyUI's node-based workflow, abstracting away the complexities of the underlying system. The server enables AI to construct image generation pipelines, adjust parameters, and retrieve results programmatically. By connecting AI systems with ComfyUI's powerful image generation capabilities, this implementation allows for dynamic creation of visual content based on textual descriptions or other inputs. It is particularly useful for applications requiring on-demand image generation, such as content creation tools, design assistants, or any AI system that needs to produce custom visuals.

Provides basic and advanced mathematical operations including addition, subtraction, multiplication, division, power, square root, and factorial calculations through an SSE-based MCP interface.

Provides cryptocurrency pricing information using the CoinGecko API, enabling users to fetch current prices of any cryptocurrency in their chosen currency.

Provides tools for evaluating and benchmarking AI explanation methods through a standard interface that can be used with AI assistants and MCP-compatible applications.

Enables prompt evaluation and refactoring via MCP protocol, allowing clients like OpenWebUI, Claude Desktop, and Cursor to access the Eliezer prompt engineer's 5-dimension scoring, ambiguity detection, and XML prompt generation.

Enables users to manage short links via cliqo.link, including creating, listing, viewing, and revoking links, as well as checking credit balances.

Stateless reducer that turns a feature description into a 9-file PRD. 17 MCP tools · multi-judge verification with weighted-average + Bayesian consensus · deterministic Hard Output Rules · research-evidence-backed strategy selection · 248 tests · part of the ai-architect ecosystem.

MCP server for cocktail recipes — search drinks, get ingredients and mixing instructions

Enables interaction with a CockroachDB instance, providing database schema resources, SQL query execution, and query analysis prompts.
