Turn any YouTube video, article, PDF, or image into a reusable Claude Code skill — without leaving your editor.
Loreto MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Loreto MCP directly instead of describing what you should do. Turn any YouTube video, article, PDF, or image into a reusable Claude Code skill — without leaving your editor.
Installation goes through your MCP client rather than a global install: point it at loreto-mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Once Loreto MCP is connected, these are the calls the assistant has available:
generate_skills — API keyget_quota — API keylist_skills — Noneget_skill — Noneverify_artifacts — Noneestimate_cost — Nonemarketplace_publish — API keymarketplace_search — Nonemarketplace_get_listing — API keymarketplace_my_metrics — API keymarketplace_my_listings — API keymarketplace_library — API keyYou will need 3 environment variables: LORETO_API_KEY, LORETO_BASE_URL, LORETO_PUBLIC_BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Loreto MCP's toolset — generate_skills, get_quota, list_skills and 11 more — is a fair guide to whether it matches your workflow. It is maintained by kopias; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
