Codex SEO MCP quickstart

The Codex CLI and the Codex IDE extension share ~/.codex/config.toml.

1. Add the servers

Sign in with OAuth (recommended)
Use an API key

~/.codex/config.toml

[mcp_servers.crakseo-seo]
url = "https://crakseo.com/mcp/seo"

[mcp_servers.crakseo-search-console]
url = "https://crakseo.com/mcp/search-console"

Then sign in once per server:

codex mcp login crakseo-seo
codex mcp login crakseo-search-console

~/.codex/config.toml

# export CRAKSEO_API_KEY=YOUR_CRAKSEO_API_KEY in your shell profile

[mcp_servers.crakseo-seo]
url = "https://crakseo.com/mcp/seo"
bearer_token_env_var = "CRAKSEO_API_KEY"

[mcp_servers.crakseo-search-console]
url = "https://crakseo.com/mcp/search-console"
bearer_token_env_var = "CRAKSEO_API_KEY"

Restart Codex. Run codex mcp list to confirm the servers are loaded.

Create API keys at crakseo.com/app/settings/keys. Never commit a real key.

2. Check the connection

codex mcp list

Expected output: crakseo-seo and crakseo-search-console with their URLs. In a Codex session, /mcp lists the loaded tools.

3. Make the first call

First verify the SEO data connection with a free call:

Use CrakSEO get_api_credit_balance to report my balance and dataCallsEnabled.
Do not purchase credits or make a paid call.

If dataCallsEnabled is false, paid data calls are unavailable; adding credits does not enable them. Continue with the free Search Console tools instead. If enabled, review current pricing and get permission before the research call below. Ask your AI:

Use CrakSEO to get the monthly Google search volume and CPC for "seo mcp" in the United States.

The client asks permission to call get_keyword_search_volume with arguments like these:

{
  "keywords": [
    "seo mcp"
  ],
  "country": "US"
}

Expected output when your account has API credits (the shape is exact; the numbers here are placeholders):

{
  "result": {
    "keywords": [
      {
        "keyword": "seo mcp",
        "searchVolume": 0,
        "cpc": 0,
        "competition": 0,
        "keywordDifficulty": 0,
        "intent": "commercial",
        "trend": [
          {
            "month": "2026-09",
            "searchVolume": 0
          }
        ]
      }
    ]
  },
  "billing": {
    "channel": "credits",
    "chargedMicros": 0,
    "chargedUsd": 0,
    "cacheHit": false,
    "balanceMicros": 0
  }
}

Expected output on a new account with no credits: a tool error with isError: true whose text is the JSON below. You aren’t charged, and the AI should send you to crakseo.com/app/indexing/credits instead of retrying:

{
  "code": "insufficient_credits",
  "message": "This call needs up to $X.XXXX in API credits. Add credits in the API account."
}

For a free first call, connect the Search Console server instead and ask: “List my Search Console properties, then show my top 10 queries for the last 28 days.”

Troubleshooting

Server not listed: check the TOML syntax. Each server needs its own [mcp_servers.<name>] table.
401 Unauthorized: run codex mcp login <name> again, or check that the key’s environment variable is exported in the shell that starts Codex.
