# Follow source

> Follow a source and add it to a Feed, creating the Feed if you name a new one. Input schema, a tools/call example and an example result.

Source: https://cotlet.dev/docs/mcp/feedly/follow_source

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)

Follow a source and add it to a Feed, creating the Feed if you name a new one.

Feedly MCP tools: https://cotlet.dev/docs/mcp/feedly.md

MCP tool: `feedly_write → follow_source`

Access: write.

Follows a source, as Follow does in Follow Sources, and adds it to a Feed. Pass feed_id for an existing Feed, or new_feed_name to create one in the same step. Following changes your account only and reaches no one, so follow_source runs without asking first; unfollow_source undoes it.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `source` | string | yes | source_id from search_sources, or a website or feed URL. |
| `feed_id` | string | no | Existing Feed to add it to. Use this or new_feed_name. |
| `new_feed_name` | string | no | Create a Feed with this name and add the source to it. |

## 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.
