Leo Pexels

Pexels wallpapers as a Leo provider package, over MCP.

Leo's wallpaper generator doesn't do this itself — it resolves a provider and asks that. This server is one, reachable as a package the hub installs at runtime rather than one it has to be rebuilt for.

What it answers

The wallpaper role in leo_mcp::providers:

search_photos({ queries, orientation })
  -> { photos: [{ source_id, download_url, description, photographer }] }

Results come back as JSON in a text content block, which is the convention the hub's bridge reads.

Configuration

Handed to this process by Leo as environment variables under their settings keys, verbatim and lower-case — only the keys the descriptor declares in entitlements.settings_read and the owner consented to, never the whole settings table.

env	where it comes from
pexels_api_key	Settings → Packages → Pexels

With nothing configured the tool returns isError naming the setting. That is deliberate: an empty answer would reach Leo as a real result.

Running it

npm install
node index.js   # speaks MCP over stdio
npm test        # checks the response mapping, no network needed

Why plain JavaScript

This ships as a git tarball pinned to a commit SHA, and npm does not reliably run build steps for a tarball URL. A TypeScript source tree would install and then fail to start on somebody else's machine, where it is hardest to diagnose.

The registry entry must name a full 40-character commit SHA. A tag reads as equally specific and is not — it can be moved after the entry is reviewed.
