Compatible with every major AI agent and IDE
What is the SemVer Version Manager MCP Server?
LLMs hallucinate software versions. They constantly fail to evaluate complex semantic version boundaries (like `>=1.4.0
Built-in capabilities (2)
Checks if a specific version satisfies a SemVer range (e.g. ^1.4.2)
Pass both versions and receive the comparison result (greater, lesser, equal). Essential for dependency resolution. Sorts a JSON array of version strings correctly following semantic versioning rules
Why Mastra AI?
Mastra's agent abstraction provides a clean separation between LLM logic and SemVer Version Manager tool infrastructure. Connect 2 tools through Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution. deployable to any Node.js host in one command.

Every tool call from Mastra AI to the SemVer Version Manager MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Why use this instead of letting the LLM read the version?
LLMs do not understand numerical boundaries logically.
Does it support pre-release tags?
Yes, it perfectly evaluates -alpha, -beta, and -rc tags according to SemVer rules.
Can it sort an array of versions?
Yes, passing an array guarantees a flawless descending or ascending output.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
