Connect SEO Score API to Windsurf (Devin Desktop)

Windsurf's editor is now Devin Desktop. Add SEO Score API to ~/.config/devin/mcp_config.json with "url": "https://seoscoreapi.com/mcp", "transport": "http" and your key in an Authorization header, or leave the header out and click Authenticate to sign in.

Once it is connected, Windsurf / Devin Desktop 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.
Open the MCP settings. In the Agents window, click Customize in the sidebar and select the MCPs tab. Under Install MCPs for, choose This computer and open its config file.
Add the server. Paste the JSON below into ~/.config/devin/mcp_config.json (Windows: %APPDATA%\devin\mcp_config.json) and refresh.
Allow the tools. Devin Local asks before it calls an MCP tool the first time; approve SEO Score API.
Ask. Try one of the prompts below.

The config

~/.config/devin/mcp_config.json

{
  "mcpServers": {
    "seoscoreapi": {
      "url": "https://seoscoreapi.com/mcp",
      "transport": "http",
      "headers": {
        "Authorization": "Bearer ssa_your_key_here"
      }
    }
  }
}

Or sign in instead of a key

{
  "mcpServers": {
    "seoscoreapi": {
      "url": "https://seoscoreapi.com/mcp",
      "transport": "http"
    }
  }
}

Keep the key in your user file, not in a project's .devin/mcp_config.json, which is meant for version control. For a per-project key use .devin/mcp_config.local.json (gitignored).

Devin Local supports OAuth for Streamable HTTP servers. Without a header the server shows Needs authentication: click Authenticate and sign in to seoscoreapi.com. In the Devin CLI the same is devin mcp login seoscoreapi.

Still on an older Windsurf build? Its MCP settings live in a different file; check your version's MCP docs and use the same URL and header.

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

The server shows Needs authentication

Either click Authenticate and sign in, or add the Authorization header with your key and refresh.

Signed in before, now it fails

Run devin mcp logout seoscoreapi, then devin mcp login seoscoreapi (or click Authenticate again).

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

Is Windsurf the same as Devin Desktop?

Windsurf's editor is now Devin Desktop, and Windsurf's documentation redirects to Devin's. Its agent, Devin Local, runs MCP servers.

Does it support remote servers?

Yes. Devin Local supports stdio, Streamable HTTP and SSE servers, with OAuth for each. SEO Score API is a Streamable HTTP server.

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"
      }
    }
  }
}
