Edit media with Splice

Connect the Splice MCP server at https://splice.film.fun/api/mcp (OAuth sign-in, or Authorization: Bearer sk_… from https://splice.film.fun/dashboard/api-keys). Without MCP, use the REST API under https://splice.film.fun/api/agents/* with the same key (reference: https://splice.film.fun/llms-full.txt).

Inputs are public https URLs, such as a media_url returned by get_job.

• Image upscale: upscale_image {input_url, upscale_factor: 2x|4x|6x}.
• Video upscale: upscale_video {video_url, target_resolution: 720p|1080p|4k} (priced per second; see list_models type video-upscale).
