serpstat-mcp-server-java
A Java MCP (Model Context Protocol) server that wraps the Serpstat Public API to provide SEO analysis tools (domain info, keywords, competitors, backlinks, related keywords, and API usage stats) to MCP clients such as Claude Desktop. It is configured via an API token provided as an environment variable and runs as a local proxy/listening MCP server process.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Uses HTTPS for HTTP requests (as stated) and takes the Serpstat token via environment variable. README claims the token is not fully logged and that timeouts are configured. However, scope granularity is not discussed, and dependency/security hygiene (SBOM, CVE status) is not provided in the supplied content.
⚡ Reliability
Best When
You want to integrate Serpstat SEO capabilities into an MCP-capable AI assistant running locally, and you can supply a Serpstat API token via environment variables.
Avoid When
You need strong, explicit documentation for rate limits, pagination, and retry/idempotency behavior for each MCP method; or you cannot manage running an external local process (JAR) securely on your machine.
Use Cases
- • Generate SEO/domain visibility reports for one or more domains using Serpstat data
- • Keyword research and related keyword expansion for content planning
- • Competitive analysis for keywords (top competing domains and SEO metrics)
- • Backlink overview for domains/subdomains
- • Retrieve Serpstat project identifiers and check API credit usage for cost-aware workflows
- • Drive SEO strategy generation inside an MCP-enabled assistant (e.g., Claude Desktop)
Not For
- • Production-grade, fully managed SaaS deployments where you need hosted scaling and SLAs from the package maintainer
- • Use cases requiring a REST/GraphQL/SDK developer experience (this package is primarily an MCP server runtime)
- • Workflows that need documented pagination/cursor semantics or formal idempotency guarantees per tool
Interface
Authentication
Authentication is token-based via environment variables; the README does not describe fine-grained OAuth scopes.
Pricing
Costs are tied to Serpstat API credits/credit limits; the package exposes api_stats to help monitor remaining credits.
Agent Metadata
Known Gotchas
- ⚠ Alpha status (v0.0.2) suggests potential breaking behavior or incomplete tool coverage.
- ⚠ Certain tools have minimum credit charges even when results are empty (keyword_competitors and get_related_keywords mention minimum charge of 1 credit per request).
- ⚠ Rate limit and retry/backoff behavior is not documented in the README; agents may need conservative request pacing to avoid credit exhaustion or throttling.
