Perplexity

Cascade chains ClinicalTrials.gov searches

Windsurf doesn't force you to run searches manually. This MCP setup lets Windsurf chain multiple steps together, starting with `search_clinical_trials` to find relevant studies based on your prompt. It looks at the results, decides which trial IDs are worth pursuing, and fetches the specifics without waiting for your next command. You get a complete list of matching trials without writing a single script. The agent handles the pagination and filtering behind the scenes, leaving you with clean, structured medical data.

Locate active enrollments instantly with this MCP Server

Finding open studies requires checking real-time recruitment statuses. The `find_recruiting_trials` tool targets studies that are currently accepting patients for specific medical conditions. Cascade runs this check and compiles a clean markdown table of open sites. You save hours of digging through web registries. Your agent grabs the exact locations and contact info, letting you build recruitment lists or patient resources in seconds.

Deep dive into trial protocols

When you need the exact science, the `get_trial_details` tool pulls down the full protocol. Cascade reads the NCT identifier, runs the query, and parses the eligibility criteria, secondary outcomes, and sponsor details. Skip copying and pasting long PDFs. Complex medical jargon gets translated into plain developer notes right inside your workspace.
