mcp-fast-time-server-go
Minimal Go service that returns/streams the current UTC time via multiple transports: stdio, HTTP JSON-RPC, and an HTTP SSE endpoint (optionally bearer-token protected for SSE).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
TLS enforcement is not described (unknown whether HTTP is plain or HTTPS-enabled). SSE supports a bearer token via -auth-token, but there is no evidence of fine-grained scopes or authentication coverage across transports. No information is provided about logging/secret handling, dependency vulnerabilities, or secure headers; only basic token gating for SSE is documented.
⚡ Reliability
Best When
You need a tiny, local, transport-flexible service for experimentation, testing, or demonstrations of HTTP JSON-RPC/SSE/stdio flows.
Avoid When
You need strong auth for all endpoints, clear rate-limit policies, or production operational guarantees; documentation does not cover these details.
Use Cases
- • Developer tooling and demos needing a simple time source
- • Load testing or benchmarking of transport paths (HTTP/JSON-RPC, SSE, stdio)
- • Integration testing for systems expecting a time endpoint
- • Building blocks for demos of agent↔service communication over stdio or HTTP
Not For
- • Production-grade time services that need robust security, auditing, or strict reliability guarantees
- • Environments requiring documented OpenAPI contracts, client SDKs, or strong operational/SLA commitments
- • Use cases needing paginated/complex APIs, retries/idempotency semantics, or rich error taxonomy
Interface
Authentication
Authentication is only described for SSE (Authorization: Bearer <token>). No auth details are provided for the HTTP JSON-RPC or stdio transports in the README.
Pricing
Self-hosted open-source project (Apache-2.0); no usage pricing described.
Agent Metadata
Known Gotchas
- ⚠ No MCP server is indicated; agents must use stdio/HTTP/SSE transports instead.
- ⚠ SSE is described with optional bearer auth only; HTTP JSON-RPC auth behavior is not documented.
- ⚠ Rate limiting and error-code contracts are not documented in the README.
