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.

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.

Create long-form (faceless YouTube) videos end to end from any MCP client: script, locked character references, storyboard, voiceover, and final video editing — with characters and style held consistent across every shot. Making long-form AI video today means 8+ tabs stitched by hand — an LLM for the script, a voice model, an image model, a video model — with characters drifting between tools and style resetting at every export. Framesail replaces the patchwork: the whole pipeline runs in one place and manages your video's context end to end. Six stages: Style (paste images, videos, or YouTube links and Framesail reverse-engineers the look, voice, and direction), Script (write it yourself or generate it in your narrative style), Reference images (auto-generated for every character, place, and prop), Voiceover (one narrator or many characters, with word-level timing), Storyboard (planned scene by scene), and Editor (captions, music, SFX, then export). No black box: you control every prompt, asset, model, and setting.

Setup checklist

  1. Start from an OpenAPI spec or a well-documented REST surface you already operate.
  2. Scope tools narrowly — expose high-value actions, not every CRUD endpoint.
  3. Use read-only credentials while testing agent behavior.
  4. Read MCP Builders Chapter 1 for a producer walkthrough.

Frequently asked questions

What is OpenAPI MCP?
OpenAPI MCP servers convert REST API specifications into discoverable MCP tools — letting agents call endpoints with structured inputs instead of bespoke integration code.
OpenAPI MCP vs hand-built MCP servers?
Auto-generated OpenAPI bridges are fast to deploy; hand-built servers let you curate tool names, descriptions, and permission boundaries for safer agent behavior.
