mcp-server-useful-tools
Provides an MCP server offering “Weather MCP” and “Stock” tools via a local SSE endpoint (example: http://127.0.0.1:8080/sse). Weather and stock examples are shown in the README output format (city/conditions; real-time stock quote details).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
README provides no evidence of TLS enforcement or authentication. Since the endpoint is shown as HTTP localhost SSE, TLS/auth may be absent or unspecified; treat as not safe for untrusted networks by default. Dependency hygiene cannot be verified from the provided content; only general stack versions are listed.
⚡ Reliability
Best When
You want a local, developer-friendly MCP/SSE demo tool server for weather and stock lookups and you control the runtime environment.
Avoid When
You require enterprise security controls, formal API contracts (OpenAPI), or documented reliability/error-retry semantics.
Use Cases
- • Agent tool use for weather lookup (e.g., by city) via MCP/SSE
- • Agent tool use for stock quote retrieval (e.g., by ticker/company name)
- • Demoing MCP tool integration with Spring Boot/Spring AI clients
- • Lightweight local “tool server” integration for conversational assistants
Not For
- • Production-grade financial or meteorological data pipelines without verifying data sources, licensing, accuracy, and uptime
- • Use cases requiring strong authentication/authorization controls
- • Use cases needing documented structured error codes, pagination, or guaranteed idempotent operations
- • Teams needing OpenAPI/SDK-based interfaces instead of MCP/SSE
Interface
Authentication
No authentication details are provided in the README. The SSE endpoint is shown as a localhost URL, suggesting it may run without auth in development, but this is not explicitly documented.
Pricing
No pricing information provided; appears to be a self-hosted open-source style MCP server.
Agent Metadata
Known Gotchas
- ⚠ README does not document the MCP protocol details (tool names, input/output schemas) beyond example Q/A text; an agent may need to inspect source code for the exact MCP tool contract.
- ⚠ SSE endpoint is shown but there is no documentation of how MCP is wired over SSE (events, request IDs, timeouts).
- ⚠ No documented authentication/authorization or network exposure guidance; localhost-only in README may not reflect production behavior.
- ⚠ No documented error formats/codes or retry/backoff behavior; agents may experience ambiguous failures and need defensive parsing.
