go-passage-of-time-mcp-server
Provides an MCP server (Go) that lets an LLM do basic “passage of time”/time-related operations, inspired by a similar Python MCP server. Can run as an stdio MCP server by default, or as an HTTP streamable server when given a port.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security posture is hard to assess from the provided materials. No auth described; HTTP mode could be sensitive without TLS/auth guidance. README does not mention logging/secret handling, scopes, or transport security.
⚡ Reliability
Best When
You want a simple, local/agent-integrated MCP time utility that runs in stdio mode or a basic HTTP mode for tooling.
Avoid When
You need well-documented APIs, robust operational guarantees (SLA, retry semantics), or strong authentication/authorization controls.
Use Cases
- • LLM tools that need current time, time arithmetic, or reasoning about elapsed/passage-of-time concepts
- • Building lightweight temporal utilities in an MCP-enabled agent workflow
- • Integrating time-related actions into agents without implementing time logic in every client
Not For
- • High-security, authenticated multi-tenant deployments (auth behavior is not described)
- • Production systems requiring strict rate limiting guarantees or published SLAs
- • Use cases requiring complex scheduling, time zones, or persistent storage semantics beyond “basic time operations”
Interface
Authentication
README does not describe any authentication/authorization mechanism for either stdio MCP or HTTP mode.
Pricing
No pricing information in provided README/repo metadata.
Agent Metadata
Known Gotchas
- ⚠ Time-related tools often need clarity about time zones/clock source; this README does not document such behavior.
- ⚠ If running over HTTP, agent integrations may need to know the expected streaming/protocol details; README only mentions `-port` at a high level.
- ⚠ No documented error codes, retry guidance, or idempotency guarantees were found in the provided materials.
