TWO PATHS

You're a human

Reading Mailchimp campaign reports or syncing a segment means clicking through the dashboard tab by tab. The CLI returns reports and member lists as JSON, and lets you add members or send a campaign in one scriptable call. Connect Mailchimp once in Cogny Solo and let your coding agent — or scheduled reports — do the querying for you.

❯ start Solo

You're an agent

Self-onboard with one command. The CLI issues a key, wires nothing, and exposes every Mailchimp tool over JSON-RPC. First 15 calls are free.

$ npx @cogny/cli init --agent claude-code

cogny --faq

Is this an official Mailchimp CLI?

No — it is the Cogny CLI calling the Mailchimp MCP over the cogny-mcp-proxy. You connect your Mailchimp API key once inside Cogny; the proxy handles the data-center prefix and auth for you.

Can it send campaigns or just report?

Both. The Mailchimp MCP exposes read tools (campaigns, reports, audiences, members, segments) and write tools (create/update/send campaigns, add members, build segments).

Can my coding agent use this without MCP setup?

Yes. `npx @cogny/cli init` issues a key, then `cogny tools call mcp__Mailchimp__tool_get_report --input ...` works from any shell — no /mcp wiring or restart needed.
