Can I use my regular TestRail password to authenticate?

Technically yes, as TestRail uses HTTP Basic Auth. However, it is highly discouraged for security purposes. The gold standard is to generate a dedicated API Key via your profile interface strictly tied to this connection.

Why isn't the API agent responding despite my credentials being correct?

TestRail requires the instance administrator to explicitly configure system-level API enablement. Ask your workspace admin to go to Administration > Site Settings > API and tick 'Enable API' box.

Can the AI rewrite my test cases explicitly inside your TestRail app?

No. Consistent with security best practices, the TestRail MCP functions only as a powerful read-only query extraction engine. It retrieves metadata, sections, milestones, and reports, protecting your ground-truth data from accidental AI deletion.

About TestRail MCP Server

Bring your overarching TestRail quality assurance orchestration directly to your developer's edge. Query comprehensive test coverage, inspect failing builds, and extract explicit test steps using natural conversation.

Windsurf's Cascade agent chains multiple TestRail tool calls autonomously. query data, analyze results, and generate code in a single agentic session. Paste Vinkius Edge URL, reload, and all 10 tools are immediately available. Real-time tool feedback appears inline, so you see API responses directly in your editor.

What you can do

Project Triage — Extract active test projects, their numeric IDs, and overall suite architecture logic
Suite & Case Isolation — Retrieve precise step-by-step logic, preconditions, and validation targets for any manual test case stored by QA
Run Execution Metrics — Instantly generate summaries around active 'Test Runs', seeing precisely which specific tests passed or failed
Milestone Navigation — Interrogate upcoming QA deadlines and release milestones without ever touching the heavy web browser application
Deep Hierarchical Search — Pull Section lists (folder hierarchies) from within projects to navigate robust test repositories visually in markdown

The TestRail MCP Server exposes 10 tools through the Vinkius. Connect it to Windsurf in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

TestRail + Windsurf FAQ

Common questions about integrating TestRail MCP Server with Windsurf.

How does Windsurf discover MCP tools?

Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.

Can Cascade chain multiple MCP tool calls?

Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.

Does Windsurf support multiple MCP servers?

Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
