social-trends-mcp-server
A Python MCP server that exposes tools for retrieving and aggregating trending topics from public Reddit and Hacker News sources (plus Hacker News search), intended for AI agents to query current social/tech trends.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Upstream APIs are described as public/no-auth, which reduces secret handling needs. However, the MCP server’s own authentication/authorization controls are not documented; if deployed without network-level protections, any caller could potentially invoke tools. TLS requirements and safe logging practices are not stated in the provided content. Dependency hygiene cannot be verified from the provided metadata alone.
⚡ Reliability
Best When
When an AI agent needs lightweight, read-only discovery of trending content from public sources, and occasional freshness/rate-limit constraints are acceptable.
Avoid When
Avoid for mission-critical decisioning where you require strong guarantees around uptime, response consistency, and robust error/idempotency behavior that are not documented.
Use Cases
- • Answer questions about what is currently trending on Hacker News
- • Retrieve hot posts from a specific subreddit
- • Search for whether a topic is being discussed on HN and/or Reddit
- • Provide an aggregated “trending topics” view combining HN and Reddit
- • Generate a quick tech “pulse” using top items from HN and selected subreddits
Not For
- • Use cases requiring authenticated/private data from Reddit or Hacker News
- • Compliance-sensitive applications that need guaranteed data retention controls or audit trails
- • High-throughput production analytics without careful rate-limit handling
Interface
Authentication
README indicates no authentication is required for the upstream public APIs used (Reddit/HN/HN search). The MCP server itself has no documented auth controls.
Pricing
No pricing information provided; likely free/self-hosted open-source library plus indirect cost from upstream API usage (rate limits) and your hosting.
Agent Metadata
Known Gotchas
- ⚠ Upstream public APIs may impose rate limits and change response formats; without documented retry/backoff, agents may experience failures under load
- ⚠ Search and trending endpoints can be freshness- and availability-dependent (HN/Reddit may throttle or intermittently fail)
- ⚠ No documented MCP server auth or usage constraints—agents may call tools freely in environments where you would otherwise restrict tool access
