Is the Writesonic MCP server free?

Yes. Activepieces is open source and free to start, and the MCP server is included on every plan, from the free cloud tier to any self-hosted deployment.

How do I connect Writesonic to Claude or Cursor?

Connect Writesonic in Activepieces, enable the server under Settings → MCP Server, then paste your server URL into your client config. It authenticates over OAuth on first use.

What can my agent do in Writesonic?

It can call 11 tools, including Blog Ideas, Blog Intros, Blog Outlines, and chain them with steps in other apps inside the same run.

Is it safe to let an agent call Writesonic?

Connections use OAuth2 with limited scopes and are stored under 256-bit encryption, with no API to read them back, so an agent gets scoped access rather than your keys.

Writesonic MCP, answered.

No. That is the point of it. One Activepieces server exposes Writesonic alongside every other piece you connect, so your client keeps a single connection.
