> Cancels a request that is waiting for signatures. Input schema, a tools/call example and an example result.

Source: https://cotlet.dev/docs/mcp/yousign/cancel_signature_request

Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Cancels a request that is waiting for signatures.

Yousign MCP tools: https://cotlet.dev/docs/mcp/yousign.md

MCP tool: `yousign_write → cancel_signature_request`

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

Works on a request in Approval or In progress. Participants are notified and can no longer open the signature page, and a cancelled request cannot be reactivated. The documents stay downloadable and the request can be duplicated. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `signature_request_id` | string | yes | Signature request ID from list_signature_requests or create_signature_request. |
| `reason` | string | yes | The reason, chosen from the list Yousign offers under Cancel request. |
| `message` | string | no | Optional custom message shown to the signers. |

## 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.
