SEO MCP servers: what each one does and how to connect it

Ahrefs says its MCP "lets AI agents securely access the Ahrefs API and enrich their answers with real Ahrefs data" and that the hosted server is for "users with a Lite plan or higher" (Ahrefs docs).

• Tools: organised in groups you can choose with a tools= URL parameter, including site-explorer-overview, site-explorer-reports, keywords-explorer, serp-overview, rank-tracker, site-audit, brand-radar-simple, brand-radar-entities, web analytics groups and gsc (Search Console data) (Ahrefs: tool categories). If your client caps the tool count, tools=essentials loads a curated set.
• Auth: you approve a consent screen, which creates a dedicated key tagged with MCP scope; you can also generate an MCP key by hand. Ahrefs' help center notes "API keys and MCP keys are not interchangeable" (Ahrefs Help).
• Pricing: Lite is listed at $129/month with "API and MCP access" (Ahrefs pricing). The help center lists 200,000 API units a month and 100 rows per request on Lite, and says "One API call costs a minimum of 50 units".
• Limits: "Using the external MCP endpoint via custom scripts, bridges, or standalone HTTP/JSON-RPC clients is unsupported and not permitted."
• Install (Claude Code): claude mcp add ahrefs https://api.ahrefs.com/mcp/mcp -t http, then run /mcp and authenticate.

SE Ranking's server at https://api.seranking.com/mcp exposes four of its APIs: the Data API (keyword research, backlinks, domain analysis, SERP data), the Project API (rank tracking, audits, competitors), the Local Marketing API and the SE Visible API for AI visibility projects (SE Ranking).

• Auth: "OAuth 2.1 with dynamic client registration", or an API key in an X-Api-Key header. SE Ranking notes that "Restricted or read-only API keys aren't available yet", so a key has the same access as your account.
• Plan: "The data available to you depends on your subscription. Not every API endpoint is available through MCP." Your account needs API access.
• Pricing: the Core plan lists at $129/month ($103.20 a month billed annually) with 25K API credits and MCP, as of October 2026 (SE Ranking pricing).
• Install (Claude Code): claude mcp add --transport http se-ranking https://api.seranking.com/mcp, then /mcp to sign in.

Semrush says its server "provides AI agents with secure access to Semrush's public APIs": all SEO API endpoints, the Trends API (depending on your Trends subscription) and the read-only Projects API methods, so it can't create projects or change settings (Semrush developer docs).

• Auth: "OAuth is the default MCP server authentication approach"; agents without OAuth can send Authorization: Apikey YOUR_API_KEY.
• Plan: for SEO data, Semrush One Starter, Semrush One Pro+, SEO Classic Pro or SEO Classic Guru, which "include 50,000 API units"; Business and Advanced plans need an API units package. Trends API plans include MCP.
• Pricing: the pricing page lists "MCP access" on Starter, shown at $165.17 a month billed annually, as of October 2026 (Semrush pricing).
• Limits: "Requests made through Semrush MCP use the same API units as direct API requests."
• Install (Claude Code): claude mcp add semrush https://mcp.semrush.com/v2/mcp -t http, then authenticate from /mcp.

Otterly.AI's server is at https://data.otterly.ai/mcp and covers "four tool categories: Workspaces & engines, Brand reports, GEO audits, and Write tools", with write tools needing write permission (Otterly.AI Help). GEO means generative engine optimization: making your content visible in answers written by generative AI.

• Auth: it "authenticates entirely via OAuth 2.0, you do not need to pass an API key".
• Pricing: the pricing page lists "MCP access" on Standard ($189/month, 2,000 MCP requests a month) and Premium ($489/month, 5,000 requests), and none on Lite, as of October 2026 (Otterly.AI pricing).
• Clients: Claude.ai, Claude Code, Claude Desktop, ChatGPT, Cursor and n8n are named.

Peec AI's server at https://api.peec.ai/mcp lets an agent check brand visibility "across ChatGPT, Perplexity, Gemini, Google AI Overviews, Google AI Mode, Claude, Microsoft Copilot, and Grok", compare competitors and inspect cited sources (Peec AI docs).

• Tools: its tools reference lists 51 read tools and 48 write tools, and says "Tool calls are rate limited to 1,000 calls per minute per user" (Peec AI: tools reference).
• Auth: OAuth 2.0 or a personal access token for clients without OAuth.
• Pricing: the pricing page lists MCP among plan features but doesn't show prices or which plan includes it, as of October 2026 (Peec AI pricing).
• Install (Claude Code): claude mcp add peec-ai --transport http https://api.peec.ai/mcp.

Profound describes its server as "our hosted server for integrating with AI tools that support MCP", at https://mcp.tryprofound.com/mcp, and lists it as "Available on: the Enterprise plan" (Profound docs).

• Tools: capability areas include visibility, sentiment, citations, shopping, agent analytics, prompts and projects.
• Auth: an OAuth flow, or an API key for a long-lived credential (Profound: connect).
• Install (Claude Code): claude mcp add --transport http profound https://mcp.tryprofound.com/mcp.

mcp-gsc is a free, open-source Python server with 20 tools for properties, search analytics, URL inspection (up to 10 URLs per batch) and sitemaps. It signs in with your own Google account (OAuth) or a service account, and keeps add_site, delete_site and delete_sitemap disabled by default. Install: uvx mcp-search-console.

QuerySail is a hosted, read-only server at https://mcp.querysail.com/gsc/mcp with five tools: list_properties, get_performance, compare_performance, inspect_urls and list_sitemaps. You sign in with OAuth 2.1 and connect Google once; it costs $8 a month after a 7-day trial (QuerySail pricing).

FreshlyCited checks whether Google has indexed each URL ("Seen by Google" or "Invisible"), pushes only the ones it hasn't seen (smart push: "Already seen — not pushed"), re-checks on day 1, 3 and 7, and for sites you verify with an IndexNow key also sends the change through IndexNow (an open "this page changed" notice that Bing and other participating engines accept; Google doesn't use it), shown as "Sent to Bing".

• Tools: check_index, submit_index_job (up to 10,000 URLs per job, with smart push), IndexNow site tools and share_job_report. See the full MCP tool reference.
• Auth: OAuth 2.1 or an API key at https://freshlycited.com/mcp.
• Pricing: MCP access is on Agency Pro ($199/month) and Agency Scale ($599/month). Index credits are used only if a link is indexed; if it's still not indexed after the day-7 re-check, the credit comes back automatically. A standard check costs 1 check credit. The free tier (10 free links to try, then 100 free checks a month, no card) doesn't include MCP.
• Limits: index checks are Google only, and FreshlyCited doesn't read Search Console or keyword data.
• Install (Claude Code): claude mcp add --transport http freshlycited https://freshlycited.com/mcp. Guides: Claude Code setup and connect FreshlyCited in Cursor.

IndexLinks (indexlinks.app) sends new and updated pages "to Bing, Yandex, Naver, Seznam and Yep through IndexNow, Google through Search Console, and Baidu", and reports crawler visits per page.

• Tools: check_site, list_websites, add_website, get_website_setup, verify_website, install_key_file, link_search_console, set_baidu_token, get_search_rankings, submit_pages, list_pages, get_page_status and request_feature (IndexLinks AI connector).

For more on the protocol, read how IndexNow works.

Rapid Indexer (rapid-indexer.com) says its server lets an assistant "submit URLs to Googlebot, check whether pages are indexed, read task results and launch traffic campaigns" (Rapid Indexer MCP).
