Indexing MCP

POST /api/indexing/mcp exposes only the indexing tools. GET and DELETE return 405. The server reports the name crakseo-indexing (earlier versions said bblg-indexing); it is a display name only, and your client identifies the server by its own config key. For new setups, the URL Indexing MCP at /mcp/url-indexing offers the same account tools plus free IndexNow and Bing submission.

Tool	Scope	Purpose
`get_indexing_account`	`indexing:read`	Prepaid credits, readiness and limits
`quote_indexing_submission`	`indexing:submit`	Preview up to 100 URLs and create an expiring quote
`submit_indexing_urls`	`indexing:submit`	Submit a saved quote once, with its `quoteId` and `idempotencyKey`
`get_indexing_job`	`indexing:read`	One job and up to 100 URL records
`list_indexing_jobs`	`indexing:read`	Workspace jobs, cursor-paginated

Authentication

OAuth 2.0 with PKCE: discovery metadata is published under /.well-known/oauth-authorization-server/api/indexing/oauth and /.well-known/oauth-protected-resource/api/indexing/mcp.
Or a manual bearer key created in Settings > API keys > Indexing-only keys (/app/settings/keys).
indexing:submit implies indexing:read but never approves spend on its own.
Requests are limited to 2 per second and 30 per minute per connection.
Clients set up with a frontpagelabs.co URL keep working without signing in again: the discovery metadata, OAuth issuer and tokens stay on the host the client uses. A manual key works on either host. An OAuth client that switches its URL to crakseo.com signs in once more.

The same five tools are also available on the main /api/mcp endpoint for keys with indexing scopes.

Example client configuration

{
  "mcpServers": {
    "crakseo-indexing": {
      "url": "https://crakseo.com/api/indexing/mcp",
      "headers": { "Authorization": "Bearer ${CRAKSEO_INDEXING_KEY}" }
    }
  }
}

Keep the key in the client’s secret store; never commit a real token.
