Frequently asked questions
Are there additional charges for querying Semrush from my agent?
The Semrush API inherently consumes 'API Units' based on the weight of each request line (Keyword ranks, Domain analytics). You are completely bound to your established Semrush Business subscription rules. Vurb/MCP itself doesn't impose surcharges.
Can I filter SEO performance based on different global markets or languages?
Yes. Most core functions such as domain_overview and keyword_overview optionally accept a targeted string code array for Regional Databases (such as 'uk', 'fr', 'de', 'es', or strictly 'us'). Just specify it organically in your LLM chatting window.
Can it check a website's technical health natively?
Yes, through the specific site_audit directive. The AI agent will ingest the aggregated technical score corresponding directly to your preconfigured Semrush Project IDs, returning high-level data regarding crawled warnings and crawler fatal errors.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
