Score38
How is this score calculated?
Weighted across six dimensions, scored 0-100.
Provenance (25): listed in an official or curated registry.
Installability (25): a runnable install command beats a declared transport, which beats a source checkout.
Maintenance (20): recency of the last push; archived entries score zero here.
Adoption (20): repository stars on a log curve.
Documentation (10) and description quality (10): parsed manifest or SKILL.md frontmatter, and a real description rather than a placeholder.
Dimensions a source cannot supply — registries publish no stars or license — are excluded from the entry's own average instead of counted as zero, so entries stay comparable across sources.
Security signals subtract up to 20. Scores are recomputed on every daily ingest.
Hands-on MCP (Model Context Protocol) server built with FastMCP — a simulated IoT sensor fleet demonstrating tools, resources, prompts, elicitation, and sampling in a layered, testable architecture.
A Rust-based MCP server that exposes local machine capabilities — file I/O, shell execution, system stats, and macOS notification triage — to AI clients over stdin/stdout. Features namespaced tool APIs, path traversal guards, strict command validation, symlink protection, and integration tests. Built with Tokio, Serde, and rusqlite.
Model Context Protocol (MCP) integration for beebjit enabling structured context exchange between the BBC Micro emulator beebjit and AI tools. Also a Python harness for direct CI/CD integration or other testing pipelines.
Two-component system bridging Kali Linux penetration testing tools with AI agents via MCP. Flask API server executes 10+ security tools (Nmap, SQLMap, Metasploit, etc.) while MCP client provides seamless AI integration for automated security workflows.
A comprehensive Claude Code skill for building production-ready MCP servers using FastMCP. Includes reference guides, runnable examples, and a complete implementation with OAuth, testing, and best practices.
A curated collection of Spring Boot projects demonstrating AI and LLM integrations, including examples of AI-powered applications, multi-provider LLM setups, and best practices for Spring AI, modular design, and integration testing.
WebMCP Inspector discovers both declarative (HTML form-based) and imperative (JavaScript API) tools exposed via the WebMCP specification. It lets you view schemas, edit attributes, execute tools, and test with Chrome's on-device Gemini Nano model, all through a live sandboxed browser session powered by Webfuse.
