Connect SEO Score API to Claude Code

Run one command: claude mcp add --transport http seoscoreapi https://seoscoreapi.com/mcp --header "Authorization: Bearer ssa_your_key_here". Or leave the header off and run /mcp in Claude Code to sign in to seoscoreapi.com in your browser.

Once it is connected, Claude Code can run SEO Score API's tools for you: SEO audits with 80+ checks, GEO and AI-visibility checks, ADA / WCAG accessibility audits, AI citation tracking, site crawls and Deep Audits, all on your own plan.

Set it up

Get a key. Copy your API key from your dashboard, or get a free one.
Add the server. Run the command below. Add --scope user to use it in every project; the default scope is this project only, for you.
Check it. Start Claude Code and run /mcp. SEO Score API should be listed as connected with its tools.
Ask. Try one of the prompts below.

The config

With your API key

claude mcp add --transport http seoscoreapi https://seoscoreapi.com/mcp \
  --header "Authorization: Bearer ssa_your_key_here"

Or sign in with your browser instead of a key

claude mcp add --transport http seoscoreapi https://seoscoreapi.com/mcp
# then, inside Claude Code:
/mcp

Shared with your team: .mcp.json (each person sets SEO_SCORE_API_KEY)

{
  "mcpServers": {
    "seoscoreapi": {
      "type": "http",
      "url": "https://seoscoreapi.com/mcp",
      "headers": {
        "Authorization": "Bearer ${SEO_SCORE_API_KEY}"
      }
    }
  }
}

With --scope project the server goes into .mcp.json at the project root. Claude Code expands ${SEO_SCORE_API_KEY} from each person's environment, so the key never lands in git, and it asks for approval before using a project server.

If you set an Authorization header, Claude Code will not fall back to browser sign-in for that server; a wrong key shows as a failed connection in /mcp.

Prompts to try first

Swap in your own URL. The plan column says who can run each one.

Ask	Tool	Plan
Audit https://example.com and list the top 5 fixes, most important first.	`audit`	Free key
How well can AI assistants read https://example.com? Run an AI readability check.	`ai_readability`	Free key
Score the conversion of https://example.com/pricing and tell me what is costing sign-ups.	`conversion`	Free key (full fix list on paid plans)
Is https://example.com visible to ChatGPT and AI search? Run a GEO audit.	`geo_audit`	Basic ($15/mo) and up
Check https://example.com for ADA / WCAG 2.1 AA issues and list the critical ones with fixes.	`accessibility_audit`	Paid plans, from Starter ($5/mo)
Generate an llms.txt file for example.com.	`llms_txt`	Any key
Crawl example.com and show me the broken pages, redirects and orphan pages.	`crawl_site`	Pro ($39/mo), Ultra or a Deep Audit credit
Track whether ChatGPT, Gemini, Perplexity and Claude mention Acme when people ask for an SEO tool. Build starter prompts, create a citation tracker and run it.	`create_citation_tracker`	Starter ($5/mo) and up
Run a Deep Audit on https://example.com and list the high-severity findings.	`deep_audit`	Pro ($39/mo), Ultra or credits

Troubleshooting

/mcp shows the server as failed

claude mcp add does not check the key when it saves. Re-add it with the right key: claude mcp remove seoscoreapi, then the add command again.

/mcp says the server needs authentication

Pick it in /mcp and follow the browser sign-in, or run claude mcp login seoscoreapi from your shell.

The tools are listed but every call fails with an authentication error

Listing tools needs no key; running one does. Check the key starts with ssa_, that the header reads exactly Authorization: Bearer ssa_... (one space after Bearer) or X-API-Key: ssa_..., and that the key was not rotated in your dashboard since.

A tool says it needs a higher plan

Some tools are on paid plans only (GEO audits from Basic, accessibility audits and citation trackers from Starter, crawls and Deep Audits from Pro). The message names the plan; your free audits keep working.

A tool says you have used this month's audits

The free plan includes 20 audits a month. The message gives the reset date and a one-click upgrade.

FAQ

Hosted server or the npm package?

Use the hosted server: nothing to install or update, and new tools appear on their own. The npm package (npx -y seoscoreapi-mcp) is there for offline or locked-down setups.

Where does Claude Code store the server?

Local and user scope live in ~/.claude.json; project scope in .mcp.json at the project root.

Is it free?

Yes, to start. A free SEO Score API key includes 20 audits a month and needs no card. GEO audits, accessibility audits, citation tracking, crawls and Deep Audits need a paid plan; plans start at Starter ($5/mo). Every tool call uses your plan's allowance exactly as the REST API does.

Do I need to install anything?

No. The server is hosted at https://seoscoreapi.com/mcp, so you add a URL, not a program. If your assistant only runs local servers, the same tools are in the open-source npm package: npx -y seoscoreapi-mcp with SEO_SCORE_API_KEY set.

API key or sign-in: which should I use?

Either works. Assistants that let you set a request header can send your key as Authorization: Bearer ssa_... or X-API-Key: ssa_.... Assistants with MCP sign-in open seoscoreapi.com, you sign in with an email link, Google or GitHub (or create a free account), approve, and you are done. Listing the tools works without either; running one needs one of them.

What can't it do?

It does not download PDF reports (a tool result is text; the audit tool returns the same data), it does not change account settings such as auto-reload, and it cannot create, upgrade or rotate keys. Those stay in your dashboard.

Prefer a local server?

The same tools ship as an open-source npm package that runs on your machine over stdio. Any client that runs local MCP servers can use it:

Local stdio server (npm)

{
  "mcpServers": {
    "seoscoreapi": {
      "command": "npx",
      "args": [
        "-y",
        "seoscoreapi-mcp"
      ],
      "env": {
        "SEO_SCORE_API_KEY": "ssa_your_key_here"
      }
    }
  }
}
