About TestLink MCP Server
Connect your TestLink self-hosted environment to any AI agent and bring your classic test management structure seamlessly into your modern AI workflow via natural language.
LangChain's ecosystem of 500+ components combines seamlessly with TestLink through native MCP adapters. Connect 10 tools via the Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures — with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Project & Plan Scoping — Retrieve all test projects, query their active states, and list all comprehensive test plans linked to them
- Suite Navigation — Browse the hierarchical folder tree of Test Suites mapping your organizational test coverage
- Test Cases Verification — Dive deep into individual test cases to read manual steps, expected results, priorities, and preconditions without navigating the legacy UI
- Build Tracking — Inspect active software builds allocated within any specific test plan to confirm QA target versions
- Environment Sanity — Check the agent’s connection and user mapping via the native whoami interrogation
The TestLink MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
