Framesail
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.

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.

Public HTAG discovery for MCP tools, API endpoints, OpenAPI ops, and agents.
typeship
Generate a typed SDK, CLI, and MCP server from any OpenAPI or GraphQL spec, and keep them current.
Setup checklist
- Start from an OpenAPI spec or a well-documented REST surface you already operate.
- Scope tools narrowly — expose high-value actions, not every CRUD endpoint.
- Use read-only credentials while testing agent behavior.
- Read MCP Builders Chapter 1 for a producer walkthrough.
How to choose
- Generic OpenAPI-to-MCP bridges ship fast but need careful tool naming for agents.
- Vendor-first-party MCP servers usually have better tool descriptions than auto-generated wrappers.
- Pair with OAuth-aware servers when APIs require user-scoped tokens.
