When to use

Use when one connection should cover most SEO research tasks. Use a focused server instead when the client limits how many tools it loads.

Connect

Claude Code

claude mcp add --transport http crakseo-seo https://crakseo.com/mcp/seo

Use crakseo-seo as the server name and https://crakseo.com/mcp/seo as the URL. Run /mcp in Claude Code to authenticate. For OAuth, scoped API keys and a free test, follow Connect and test. Other clients: ChatGPT, Cursor, Codex, VS Code, Cline, Gemini CLI, Grok and Muse. A remote connection does not require a marketplace listing. Registry names are distribution identifiers, not a claim of directory approval.

Verify without spending

Errors

Code	Meaning	What to do
`insufficient_credits`	The API credits wallet can’t cover the call’s maximum price.	Add credits at https://crakseo.com/app/indexing/credits, then retry the same call. The failed call isn’t charged.
`forbidden`	The connection doesn’t have the scope this tool needs, for example `seo-data:read` or `console:write`.	Reconnect and grant the scope named in the message, or use an API key that has it.
`not_connected`	Google Search Console or Bing Webmaster Tools isn’t connected, or no connected property covers the URL.	Open the connect link in the message and sign in with the account that owns the property.
`invalid_input`	A parameter is missing or out of range.	Read the message, which names the field, fix the argument and retry.
`confirmation_required`	A paid indexing submission doesn’t have the account owner’s approval for this exact quote.	`submit_indexing_urls` returns `status: "needs_confirmation"` with a `confirmationUrl`. Send the owner there to approve, then retry with the same `quoteId` and `idempotencyKey`. The agent can’t approve spend.
`wallet_frozen`	API credit spending is suspended on this account after a refund or dispute.	Contact support@crakseo.com.
`budget_exceeded`	The account’s daily API credit spending limit, or the service’s daily data budget, is used up.	Retry tomorrow.
`disabled`	SEO data calls aren’t switched on for this deployment yet.	Use the free Search Console and URL indexing tools meanwhile. `get_api_credit_balance` reports `dataCallsEnabled`.
`supplier_unavailable`	The data supplier couldn’t be reached or is rate limiting.	Retry later. Failed data calls are free.
`supplier_unknown`	The data supplier didn’t answer in time or sent an unreadable response.	Retry later. Failed data calls are free.
`supplier_error`	The data supplier refused the request or returned no data.	Check the arguments (for example the location name) and retry. Failed data calls are free.
