hacker-mcp-server-POC
An MCP (Model Context Protocol) server that exposes Hacker News data as callable tools. It provides tools to fetch news lists (top/new/best), fetch story details with comments, fetch user profiles/recent activity, and search Hacker News via the Algolia API; it includes input validation with zod and HTTP calls via axios.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
No server authentication or scope-based authorization is described. Communication transport is STDIO by default (not HTTP/TLS), so TLS enforcement is not clearly applicable. The README mentions no required environment variables/credentials; dotenv is supported but not required. The README explicitly notes that network calls should be made more resilient (retries/timeouts) and that helper functions may assume fields exist—this can affect robustness but is not a direct auth/security control.
⚡ Reliability
Best When
You want a lightweight, local/STDIO-connected MCP tool surface for small-scale HN retrieval and experimentation.
Avoid When
You need robust error semantics, strong auth, or clearly documented rate limiting/pagination for high-volume usage.
Use Cases
- • Agentic retrieval of Hacker News stories, metadata, and comments
- • Summarization or analysis of recent HN discussions by an AI agent
- • Search-based browsing over HN content for themes/keywords
- • Building an MCP-connected workflow that needs lightweight HN data access
Not For
- • Production-grade high-reliability integrations without additional hardening
- • Use cases requiring fine-grained permissions, user authentication, or audit logging
- • Workloads needing strict rate-limit control or pagination beyond the first 10 results
Interface
Authentication
No authentication is described for the MCP server interface; it appears to act as an unauthenticated wrapper over public HN/Firebase and Algolia endpoints.
Pricing
No pricing information provided; appears to be a code repository for running locally.
Agent Metadata
Known Gotchas
- ⚠ Lists and details are limited (e.g., “returns first 10”); there is no documented pagination strategy.
- ⚠ Helpers reportedly return null on failure and may not guard against missing fields (e.g., kids/comments or url), which can produce unexpected null/shape results for agents.
- ⚠ Default transport is StdioServerTransport; agents must launch/connect via STDIO as expected.
