lurk_info
Get subreddit metadata (subscribers, active users, description)
An 800-comment Reddit thread costs ~120K tokens as raw JSON. Lurk delivers the same thread β full depth, every expanded reply β in a fraction of that.
Most Reddit tools fetch top-level comments and stop. The useful stuff is buried 4-5 replies deep. Lurk expands every collapsed branch, resolves every +N more replies placeholder, and reconstructs the full comment tree. Then compresses it into compact tab-delimited notation before it reaches your model.

How Token Savings Work
The Go binary preprocesses everything before tokens reach your model:
Fetch β Hits Reddit's JSON endpoints, recursively expands every collapsed more placeholder
Extract β Strips the 50+ unused fields per comment (gildings, awards, flair, metadata) down to 5-6 that matter
Compress β Formats into compact tab-delimited notation: d0 180 Recent-Success-1520 If you can host Kimi 2.5...
The result (benchmarked across 12 threads, 452 comments, 6 subreddits):

94% fewer tokens than JSON. 44% fewer than Markdown. Savings scale with thread depth β shallow quips save ~10-25% vs markdown, deep technical threads save 50-64%.
Smart Comment Limiting
Threads with 200+ comments get a preview first instead of dumping everything:

#post r/ClaudeAI u/poster 422pts 93% 805cmt 2026-01-28
Finally We have the best agentic AI at home
#comments 461

...
#warning 805 total comments, showing 461. Use limit=N for top N by score, or limit=0 for all (~31K tokens).
Claude sees the warning and decides whether to fetch everything or grab the top 50 by score. No surprise 31K-token dumps.
What You Get

Lurk works without any authentication. But if you want 6x the rate limit (60 req/min instead of 10):
bash
lurk auth
This opens Reddit's app creation page, walks you through the 5-minute setup, tests your credentials, and saves them. One-time process. Lurk handles token refresh automatically.
bash
lurk auth --status # Check if credentials are configured
lurk auth --clear # Remove saved credentials
You can also set credentials via environment variables in your MCP config:
u/Recent-Success-1520 (180 pts)
If you can host Kimi 2.5 1T+ model at home then it tells
me you have a really big home
u/No_Conversation9561 (82 pts)
not in my home
u/rookan (60 pts)
yeah, my 16GB VRAM card can easily handle it /s
