## Give this to your agent

```text
Use my connected Agentik MCP server for this job: literature review.

Write a short literature review. First ask me for the research question, the field and the years to cover.

Find the most cited and the newest works with openalex/search-works. Check DOIs, journals and recent articles with crossref/search-works. Find research described in other words with exa/search. Get background on the key concepts with wikipedia/page-summary.

Finish with a structured review (what is established, what is debated, what is new), a reference list with DOIs, and the open questions.

Before running anything, inspect each tool with inspect_tool, ask me for any input you don’t have instead of inventing it, and tell me the total price. Wait for my go. At the end, tell me what Agentik charged.
