quarkus-mcp-server-basic-tool
Provides a “basic” MCP server tool implementation for agents (run via a Java/Quarkus-style artifact) and demonstrates running it through an MCP client (mcp-cli) using an OpenAI provider.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Based on provided content only: README instructs setting OPENAI_API_KEY in an environment variable but also includes a seemingly hard-coded key-like string in documentation (high risk if replicated/committed). No server-side auth, authorization scopes, TLS requirements, or secret logging protections are described.
⚡ Reliability
Best When
You want a minimal starting point to understand MCP server wiring and tool execution from an external MCP client using Java.
Avoid When
You need strong security controls, documented error/rate-limit behavior, or enterprise reliability/SLA guarantees out of the box.
Use Cases
- • Agent-based task execution via MCP by exposing a small set of server tools
- • Local/dev testing of MCP server integration using Java tooling
- • Building custom agent tool backends in Java and wiring them to an MCP client/provider
Not For
- • Production-grade MCP deployments without additional hardening, monitoring, and documented contracts
- • Use as a secure proxy for sensitive data if auth and secret handling are not implemented in the server/tooling itself
Interface
Authentication
The README configures the client-side provider authentication via OPENAI_API_KEY. It does not describe any server-side auth/authz for the MCP server itself.
Pricing
README indicates usage of an OpenAI provider through mcp-cli, implying consumption-based model pricing, but no pricing details are provided for this package itself.
Agent Metadata
Known Gotchas
- ⚠ README provides a sample env var containing what appears to be a real-looking API key string; ensure you never commit or expose secrets and use proper secret management in practice.
- ⚠ No MCP tool contract details (tool names, input/output schemas, error formats) are shown in the provided content, so agent integration may require inspecting code/release artifacts.
- ⚠ No documented guidance on retries, timeouts, or idempotency semantics for MCP tool calls is provided.
