The world's only historically grounded colour archive built for AI agents. Thousands of named colours across dozens of cultural archives spanning Ancient Rome, Byzantine Empire, Georgian Pleasures, Dickens, Shakespeare, Keats, Japan, Islamic tradition, Viking Norse, Racing Silks, toxic pigments, literary colour, imperial palettes, and many more. Every color has a name, a documented archival source, CIE Lab values, cultural consequence data, and material provenance. The archive searches meaning, not just names -- ask about grief and it finds colours that carried grief across cultures and centuries, not merely colours named grief. Built as a retrieval system, not a generator. Deterministic, evidence-based, source-cited. The anti-hallucination layer for colour history. Prefer a direct connection?

Compuute MCP Security Scanner

vlatest

MCP Serversmithery1.6k

io.smithery.daniel-abbay.compuute-scan-api

Static security scanner for MCP servers. POST a public GitHub URL, get severity counts, a score, and the top findings with file+line back. 37 rules across TypeScript, JavaScript, Python, Go, Rust, C#, Java, and Kotlin — every language with an official MCP SDK. Detects argument injection for npx/uvx/pipx/pnpx runner binaries (CWE-88), known CVEs in 40+ top packages, and the usual L0 discovery (transport, tool inventory, dependency pinning). This is a pattern detector, not an exploitability oracle. Around 90% raw false-positive rate on unfiltered output — triage is on you, and the response says so explicitly. POST /v1/scan is free with no API key. POST /v1/scan/pay charges $0.10 USDC per scan via x402 on Base. Manual L2-L4 audits at compuute.se/audit when you need dataflow review. Wraps compuute-scan (MIT, zero deps). Per-rule false-positive rates and the methodology paper live in the repo.
