Write the summary of a call again from a template, with extra instructions you give.

Fathom MCP tools: https://cotlet.dev/docs/mcp/fathom-video.md

MCP tool: `fathom_video_write → regenerate_summary`

Access: write. Confirm: waits for the user's OK before it runs.

Selects a summary template on the call page, adds your instructions with the gear icon and clicks Regenerate Summary. The new text replaces the summary shown on the call, including for people the call is shared with. Set apply_to_future to true to also click Apply to Future Summaries, which keeps the instructions for that template. Summary customization needs a Premium or Team plan. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `call_id` | string | yes | Call ID from list_calls: the number in the call address, fathom.video/calls/{call_id}. |
| `template` | string | no | Name of a summary type as listed on the call page. Default: the one selected now. |
| `instructions` | string | no | Extra guidance for the AI, for example a tone or a section to add. |
| `apply_to_future` | boolean | no | true to keep the instructions for future summaries of this template. Default: false. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
