seodata.dev MCP server

Keyword search volume, CPC, competition and similar keywords for AI assistants, in 50+ countries. A remote MCP server: nothing to install, and it works without an account.

https://mcp.seodata.dev/mcp

• Transport: Streamable HTTP
• Auth: optional. OAuth 2.1 (PKCE, dynamic client registration, client ID metadata documents) or an API key as Authorization: Bearer sd_live_…
• Registry: dev.seodata/keywords
• Docs: seodata.dev/mcp

This repository holds the connection configs and registry metadata. The server itself is hosted by seodata.dev; there is no code to run.

Connect

Claude (claude.ai and Desktop). Settings → Connectors → Add custom connector. Name it seodata.dev and paste the URL. Claude opens the sign-in page the first time it needs more than the anonymous limit.

Claude Code

claude mcp add --transport http seodata https://mcp.seodata.dev/mcp

Then run /mcp inside Claude Code to sign in, or add --header "Authorization: Bearer sd_live_…" to use an API key.

ChatGPT. Settings → Apps → Advanced → turn on developer mode. Create an app with the URL and OAuth as the authentication method.
