SISTRIX SEO Toolbox

What SISTRIX SEO Toolbox MCP server does

SISTRIX SEO Toolbox MCP server connects MCP clients to selected SISTRIX SEO data. Its tools cover domain overviews, visibility history, keyword counts, competitor discovery, keyword opportunities, domain structure, rankings, keyword metrics, backlink data, AI visibility, SISTRIX projects, and Amazon information. A separate credits tool reports the remaining API balance, while a lists tool exposes available country indices, SERP features, and AI models.

The server also provides four MCP prompts for repeatable workflows: an SEO health check, keyword research, competitor comparison, and an AI visibility report. These prompts combine multiple tool calls and return structured analysis, such as trends, competitors, opportunities, cited sources, and suggested actions.

How it works

The application runs as a local Rust executable and communicates with an MCP client over stdio. Clients can pass the SISTRIX API key and a default country through environment variables. Domain-oriented tools accept a target such as a domain, host, path, or URL, together with a scope, country, and row limit.

SISTRIX charges most API operations according to returned rows or a documented flat cost. Tool descriptions include cost information, and the implementation applies row limits and a response budget to keep requests bounded. The sistrix_credits operation is available for checking the current balance before using credit-consuming reports.

When a curated tool does not cover a documented SISTRIX method, sistrix_api provides access to other API methods, including examples from the AI, marketplace, and project namespaces. Requests use the API key in the POST body rather than in the URL. The server also retries selected rate-limit, server, and network failures with backoff, and maps documented SISTRIX error codes to explanatory hints.

Setup and configuration

Install the binary with Cargo, build it from the Git repository, or use the published Docker image. A SISTRIX API key is required; the README directs users to the SISTRIX account API page to create one. API access is available from the SISTRIX Plus package onward and uses a weekly credit budget.

The primary environment variables are:

• SISTRIX_API_KEY: the SISTRIX credential.
• SISTRIX_COUNTRY: the default country index, such as de.

A country supplied through SISTRIX_COUNTRY becomes the default for tool calls unless a request specifies another country. The executable also supports an API-key command-line option and a connection check command.

Tools and capabilities

SISTRIX SEO Toolbox MCP server includes these capability groups:

• Domain status, visibility trends, keyword counts, competitors, structure, and rankings.
• Keyword volume, cost-per-click, intent, SERP features, and related research.
• Backlink profile and link-text data.
• AI brand visibility, cited sources, tracked prompts, and competitor comparisons.
• Amazon rankings, price history, and review history by ASIN.
• SISTRIX project data, including optimizer rankings, on-page crawl results, and tracked SERPs.
• A general API tool for documented methods outside the curated set.

The documented clients include Claude Desktop, Cursor, Windsurf, VS Code with GitHub Copilot, Claude Code, and other MCP clients that support stdio. The README gives client configuration examples using the sistrix-mcp executable.

Limitations and notes

Using the server requires both a SISTRIX API key and access to a SISTRIX package that includes API access. API calls consume a weekly credit allowance, although the credits and lists operations are marked free in the tool table. Costs vary by method, returned row count, or flat request pricing, so larger reports can consume more credits.

The server is designed around the SISTRIX API and does not provide independent SEO crawling or search-engine data. Results depend on the country index, target scope, and data available from SISTRIX. The general API tool increases coverage but requires the caller to know the relevant documented SISTRIX method and its parameters.
