Best AI SEO Tools With an API in 2026
A ranked list of AI SEO tools that expose an API or MCP server in 2026, ordered by how much useful surface a developer or coding agent can drive.
An API turns SEO work into something a script or a coding agent can drive. Instead of clicking through a dashboard, you call an endpoint or point Claude Code at an MCP server, and the agent pulls rankings, reads crawler logs, drafts a fix, and opens a pull request in one conversation. The surface a vendor exposes decides which of those steps are even possible. A tool with a polished UI and no API is a dead end for automation. A tool with a real API or MCP server is a building block.
This list ranks AI SEO tools by how much useful surface they expose to a developer or coding agent, not by how many endpoints they claim. Only vendors whose directory entry actually documents an API or MCP server are included. Pricing and feature claims come from each vendor's entry. Where a number is not published, we say so rather than guess.
1. Promptwatch
Promptwatch exposes the broadest surface on this list, and it is included from the entry paid plan rather than gated to Enterprise. The MCP server runs over a hosted streamable HTTP transport with OAuth or a Bearer key, and the same server backs the ChatGPT plugin and the Claude connector, with Cursor connecting through a config file. A read-only key hides the write tools, which is the single most important safety property for an agent that runs on a schedule.
The read surface is what makes it rank first. An agent can list and inspect tracked prompts, read visibility time series, pull citations and top cited pages, and read Reddit and YouTube citations, the two channels that matter most for off-domain reach. It can read a competitor heatmap, list content-gap prompts and recommendations, and expose the query fan-out structure around a seed query. The crawler and visitor side is where Promptwatch pulls ahead: an agent can read AI crawler trends and top crawled pages, which is the evidence you need before proposing a robots.txt or crawl fix, and then read the visitor trend, top pages, and top sources that follow. Ads and shopping read tools cover ads, ad prompts, and shopping items. The write surface is smaller and deliberate: create reports, manage the action board, add tracked prompts, add tracked shopping products, and drive the Content Agents workflow into a connected CMS. That is a full measure, decide, and act loop over an API, which is why Promptwatch leads this list. Brand plans start at $95 per month, with a free Explore tier.
2. Outrank
Outrank ships a documented REST API, webhooks, and an official CLI built for coding agents like Claude Code and Cursor. The content autopilot researches keywords, writes and publishes SEO articles on a schedule, and builds backlinks through a verified exchange network, and the API and CLI let a coding agent drive that production loop programmatically. The plan is one flat $99 per month for 30 articles, with upgrades to 60 or 90, and unlimited users on every plan. It ranks second because the REST API plus CLI is a real developer surface for content production, and the CLI is explicitly built for coding agents. There is no MCP server, so agents drive it through the API or CLI, and there is no published AI crawler log or citation view.
3. Encited
Encited hosts an MCP server at encited.com/api/mcp for Claude, Claude Code, Cursor, ChatGPT, and Lovable, with a one-line add command for Claude Code. Its workflows cover Search Console mining, AI visibility with fan-out query clustering, technical SEO audit, local SEO, content and keyword research, and competitor research, and the server sits on top of real infrastructure: AI-optimized pre-rendering for JavaScript sites with an edge proxy, crawl-log analysis, and a site auditor that runs up to 30,000 pages per audit with auto-fixes. Pricing starts at $19 per month for Basic, with a 14-day free trial. It ranks third because the hosted MCP surface is real and the crawl and pre-render infrastructure an agent needs to act on technical SEO sits underneath it.
4. SEO MCP
SEO MCP is a 39-tool MCP server across site auditing, Search Console, GA4, Google Indexing, IndexNow, Core Web Vitals, schema and validation, and sitemaps. It works with Claude, Cursor, Windsurf, and any MCP-compatible client. One config line connects your agent, and the agent runs an audit, submits URLs for indexing, pulls keyword performance, validates schema, and generates a report in one conversation. The free tier gives 50 calls per month and 36 of the 39 tools, with Pro at $29 per month for 5,000 calls and all 39 tools. It ranks fourth because the MCP surface is broad and the value is hard to beat, though it stops at the classic SEO stack and does not reach into AI crawler logs or citation measurement.
5. DispatchSEO
DispatchSEO is an open-source SEO manager that runs over MCP for Claude Code, Codex, Cursor, the ordinary Claude app, Gemini CLI, and Copilot. Its tool set covers queue, keywords, rankings, pages, GSC stats, backlink prospects, trend topics, and site profile, and it writes one article a day with daily rank tracking and AI Overview tracking, shipping everything as pull requests on GitHub Actions in your own repo. Self-host is free under AGPL-3.0 and has every feature, with paid cloud plans from $20 per month annual that bundle SERP and volume data and one-click GSC. It ranks fifth because the MCP surface is real and the PR workflow is exactly what an acting agent wants, with the focus on content production rather than visibility measurement.
6. AthenaHQ
AthenaHQ tracks eight engines on day one and rolls citations, sentiment, traffic impact, and query types into a unified GEO score, with API access now included even on Starter and unlimited seats with role-based access on all tiers. The Action Center turns visibility data into assignable tasks for schema generation, content reformatting, and LLM metadata optimization. Pricing starts at $295 per month with a free tier. It ranks sixth because the API is included from Starter and the action queue is scriptable, though the credit-based billing makes automated high-frequency calls expensive, and there is no published MCP server or crawler-log surface.
7. Temso AI
Temso AI is the closest lookalike to Promptwatch in shape: daily visibility tracking from live model UIs, citation analytics, AI bot-visit logs pulled from GSC and CDN or server logs, an agent that drafts content and on-page work, plus MCP on all plans and a REST API and Looker connector from Growth. Starter is $89 per month for 50 prompts on three models and 10K AI bot visits, with unlimited projects and seats on every paid plan. It ranks seventh because MCP on all plans and a REST API from Growth are a real developer surface, though the REST API and the meaningful bot-log volume both start at Growth at $199 per month, and there is no published visitor-to-conversion attribution.
8. Qwairy
Qwairy sells a six-module GEO suite with MCP on all paid plans and a REST API from Growth. The module list reads like a full-stack sitemap: Cockpit, Monitor, Act, Analyze, Optimize, and Measure, with prompt tracking, response analysis, citation sources, sentiment, a Content Studio, and site readiness diagnostics. Starter is €79 per month for 100 prompts and 1,300 credits, Growth is €199 per month with the REST API, and Business is €449 per month with crawler analytics, Looker, and alerts. It ranks eighth because MCP on Starter and a REST API from Growth are real surfaces, but the credit meter pauses new analyses when credits hit zero, and Claude, Mistral, and DeepSeek are API samples rather than live UIs.

Who should pick which
Pick the platform that exposes the surface your agent actually needs. If you want an agent that measures AI visibility, reads crawler logs, and then publishes content from the same server, Promptwatch is the only one on this list that covers both halves over API and MCP. If you want a coding agent to drive content production through a CLI, Outrank is built for it. If you want a hosted MCP server with crawl and pre-render infrastructure underneath, Encited pairs them. If you want a cheap, broad technical SEO server for an agent, SEO MCP is the value pick. If you want an open-source MCP server your coding agent drives, DispatchSEO is the free self-host option. If you want a scriptable action queue with an API from Starter, AthenaHQ is the execution layer, budget the credits. If you want MCP on every plan and a REST API from Growth, Temso and Qwairy both expose it, with Temso closer to Promptwatch in shape and Qwairy credit-metered. Then keep the key read-only until you trust the loop.
The recommendation
For API-driven SEO in 2026, the deciding factor is how much of the measure, decide, and act loop an agent can run over the exposed surface, not how many endpoints exist. Promptwatch is the platform we would build an agent on, because the MCP server and REST API v2 are included from the entry paid plan, the read surface covers prompts, citations, crawler logs, and visitor analytics, and the write surface drives Content Agents into a connected CMS. Start with the free Explore tier and a read-only key, then move onto a paid plan at Promptwatch or read the Promptwatch review.
