How to Use the DevSkiller MCP in Windsurf

Q: How does Cascade know which DevSkiller test to send?

Cascade runs the listavailabletests tool to read your entire catalog of configured assessments. You just tell it which role you are hiring for, and the agent matches the request to the right test ID.

Connect DevSkiller to Windsurf and let Cascade automate your technical screening workflow from test invites to scoring.

Automate test invites with Windsurf

The `invite_candidate_to_test` tool lets Cascade send technical assessments directly to applicants without you clicking through a dashboard. You tell Windsurf to screen a new batch of developers, and it pulls the right exam from `list_available_tests` before firing off the emails. Cascade handles the follow-up logic autonomously. It checks `list_recently_sent_invitations` to confirm delivery and monitors `list_test_invitations` to track completion status. You just check the final results in your editor.

Fetch candidate profiles instantly

The `search_candidates_by_identity` tool finds specific applicants by name or email keyword straight from your IDE. Once Cascade locates the right person, it pulls their full details using `get_candidate_profile`. You don't have to switch tabs to read their background. Cascade grabs the data, formats it into a summary markdown file, and drops it right into your workspace. If you need a broader view, it can run `list_assessment_candidates` to map out your entire active talent pool.

Analyze assessment reports via MCP Server

The `get_candidate_assessment_report` tool gives your agent the exact scoring breakdown for any completed technical test. Cascade reads the raw data and highlights exactly where a developer struggled or excelled. You can ask Windsurf to filter out the noise. It uses `list_high_score_candidates` to isolate applicants who beat a specific threshold. Then it cross-references your current API limits using `get_account_metadata` to ensure you have enough quota left for the next round of hiring.

DevSkiller handles the actual test execution and grading on their end. Windsurf pulls those finalized grades using the `get_candidate_assessment_report` tool to show you the results in your editor.

Cascade runs the `list_available_tests` tool to read your entire catalog of configured assessments. You just tell it which role you are hiring for, and the agent matches the request to the right test ID.

You might be hitting your account limits. Ask Windsurf to run `get_account_metadata` to check your API quota. Also, verify the candidate email isn't already listed in `list_recently_sent_invitations`.

The server processes applicant names, email addresses, and technical test scores. Vinkius runs this connection through an ephemeral V8 Isolate Sandbox, meaning your recruitment data passes directly to your IDE and vanishes from memory the moment the session ends.
