Semrush for AI agents

Semrush is an SEO and marketing toolkit for keyword research, competitor analysis, backlink audits, and ad campaign data, used widely by marketing teams. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

04 · AUTH AND DATA

How Semrush connects.

Users add their Semrush api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Semrush connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Semrush and Arc0, answered.

Q01

Can I use Semrush with Claude, ChatGPT or Cursor?

Yes. Connect Semrush to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Semrush actions you allow.

Q02

How do users connect Semrush?

Users add their Semrush api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Semrush actions can my agent take?

37 in total: 0 read, 37 write and 0 destructive, such as “get anchor texts”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Semrush?

Yes. Allow read actions and deny writes in the Semrush policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Semrush too?

Yes. The same Semrush connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
