An MCP SEO tool is a Model Context Protocol server that exposes keyword, SERP, crawl, or Search Console actions to an AI host over JSON-RPC.

TLDR

  • First-party GSC (31 Jul–28 Aug 2026): mcp seo tool (7 / pos 81), seo tools mcp (8 / 74), seo mcp (5 / 83), chatgpt seo mcp (5 / 85). This extensions hub is the landing URL.
  • MCP is an open protocol. Hosts talk to servers with JSON-RPC 2.0 (specification 2026-07-28).
  • Servers advertise tools, resources, and prompts. SEO vendors wrap their APIs as tools.
  • DataForSEO’s official remote endpoint is https://mcp.dataforseo.com/v3/mcp (DataForSEO MCP).
  • Skills (SKILL.md) are instructions. MCP adapters are live tools. Install both. Do not replace one with the other.

What the protocol exposes

MCP names three roles: host (Claude Desktop, Cursor, Antigravity, ChatGPT), client (inside the host), server (your SEO API wrapper). The 2026-07-28 spec uses JSON-RPC messages. Servers offer tools the model can call with structured arguments.

For SEO that usually means: keyword lookup, live SERP, backlinks, on-page crawl, or Search Console query. The DataForSEO skill pillar is the method for that vendor’s API. This hub is the adapter list.

A server is not a strategy. It returns rows. The skill pack decides what to do with the rows.

The eight adapters on this hub

The cards below this article are the eight SEO Skills AI extension adapters (Ahrefs, Banana, Bing, DataForSEO, Firecrawl, Profound, SE Ranking, Unlighthouse). Install example:

npx @seoskillsai/cli ext add dataforseo

ChatGPT queries such as chatgpt seo mcp still land here or on the ChatGPT hub. Do not fork a ChatGPT-only MCP slug. Custom GPT Actions are OpenAPI, not MCP; the ChatGPT hub covers Actions.

Claude GSC how-to stays on Connect Claude to Google Search Console. That page is Search Analytics. This page is the adapter directory.

Connect a vendor MCP server

DataForSEO documents a remote HTTP server (MCP page):

https://mcp.dataforseo.com/v3/mcp

Cursor example from that vendor page uses "url" plus a Basic Authorization header. Antigravity custom servers edit mcp_config.json via MCP Store → Manage MCP Servers (Antigravity MCP). Do not paste Cursor "url" blocks into a client that expects a different key without reading that client’s docs.

Keep credentials in env vars or the vendor OAuth prompt. Do not commit API passwords in mcp.json.

Listicles titled “SEO MCP servers” stop at retrieval. This product keeps the skill pack as the orchestrator. Harness reads the same SKILL.md shape from disk: Harness skill folders.

FAQ

What is an MCP SEO tool?

A protocol server that lets an AI host call SEO APIs as tools. It is not a ranking plugin and not a skill file.

How do I connect DataForSEO?

Point the client at https://mcp.dataforseo.com/v3/mcp or run npx -y dataforseo-mcp-server with API env vars, per DataForSEO’s own MCP page.

Does ChatGPT use MCP for SEO?

ChatGPT can attach MCP apps in developer/plugin flows. This catalog still uses Custom GPT Actions on /chatgpt for OpenAPI. Same jobs, different wire format.

MCP vs an SEO skill?

Skills tell the agent how to work. MCP gives the agent live data. You want both.

Where are the eight adapters?

On this page, in the grid under the article. There are no per-extension public URLs.
