OpusClip Pro MCP connector vs the Sume hosted MCP: what differs
OpusClip lists a Video Editing API, Scheduler API and MCP connector on Pro. Sume has a hosted MCP with trim and inspect tools. What each gives an agent.
OpusClip's pricing page lists a Video Editing API, a Scheduler API and an MCP connector on its Pro and Business plans, so an agent on Pro can drive its clipping. Sume's hosted MCP at https://mcp.sume.com/mcp exposes lower-level tools such as video_inspect and video_trim, with no clip-picking of its own. If you want an agent to choose viral moments for you, OpusClip is the closer fit; if you want to cut where your own logic says, Sume is.
What OpusClip lists
The page shows Free at $0, Starter at $15 a month, Pro at $29 a month and Business on request. It lists the Video Editing API, Scheduler API, MCP connector and Zapier on Pro and Business (Pro Zapier limited to 300 credits a month) and CMS integration on Business only. Media expires after 3 days on Free and 29 days on Starter, and Pro has 100GB of storage.
| Capability | OpusClip (per its page) | Sume (per its docs) |
|---|---|---|
| MCP | MCP connector on Pro and Business | Hosted MCP at https://mcp.sume.com/mcp |
| Cutting tool | Video Editing API | video_trim, one range per job, $0.02 |
| Look at a clip | Not stated on the page | video_inspect with optional frames and transcript |
| Posting | Scheduler API | Not offered as a tool in the docs I read |
| Entry price | Pro $29 per month | Prepaid USD balance |
How an agent would use Sume's tools
The docs describe a flow: video_inspect to read the clip, video_trim with a start and either end or duration, then jobs_wait and jobs_result for the output. Writes need an idempotency_key, and under OAuth the mcp:write scope. The trimmed output is a new artifact, never the source.
Steps: connect and cut
- Add the hosted MCP URL to your client and sign in with OAuth or an API key.
- Import the source clip so it lives on media.sume.com.
- Ask the agent to inspect it, pick start and end times from the transcript, and call video_trim.
- Read the result artifact and caption it with a standalone caption job if wanted.
What Sume does not do
Sume does not auto-select highlights, score virality or schedule posts. Those are the parts OpusClip markets. The agent doing the choosing is your model, reading the transcript and frames from video_inspect.
What the agent needs to be safe
Whatever tool you hand an agent, set limits. On Sume, writes need an idempotency_key so a retried call does not create a second job, and the hosted MCP uses OAuth scopes such as mcp:write. A trim costs $0.02, so a runaway loop is cheap but not free; cap the number of calls in your prompt. Ask the vendor how OpusClip's connector authenticates and what a mistaken call costs before you wire it to an unattended agent.
Storage and expiry
OpusClip's page says media expires after 3 days on Free and 29 days on Starter, with 100GB fixed storage on Pro. Sume produces artifacts on media.sume.com and imports are the entry point for your own files. I did not find a retention figure for artifacts in the pages I read, so copy outputs you need to keep to your own storage as soon as a job completes.
Verdict
OpusClip suits an agent that wants ready-made clips. Sume suits an agent that needs primitives it can chain. Check OpusClip's own docs for what its connector calls, since the pricing page only names it.
