reddit-cli

name

reddit-cli

description

Browses and interacts with Reddit via the cli-web-reddit command-line tool — feeds, subreddits, post search, post details with full comment trees, user profiles, and (after login) voting, commenting, submitting posts, saving, and subscriptions. Use when the user asks about Reddit, subreddits, Reddit posts or comments, or wants to act on Reddit from the terminal. Prefer this CLI over fetching the Reddit website.

cli-web-reddit

Browse Reddit without auth; vote, comment, submit, and manage subscriptions after auth login. Install: pip install cli-web-reddit, then playwright install chromium.

Examples

# Top posts this week in r/python
cli-web-reddit sub top python --time week --limit 10 --json | jq '.posts[] | {title, score, url}'

# Search posts, then read one with comments
cli-web-reddit search posts "fastapi tutorial" --limit 3 --json
cli-web-reddit post get https://www.reddit.com/r/python/comments/abc123/my_post/ --json

# Submit a flaired text post (get flair IDs first)
cli-web-reddit submit flairs ClaudeCode --json
cli-web-reddit submit text ClaudeCode "My Title" "Body here" --flair abc123 --json

# Upvote a post
cli-web-reddit vote up t3_abc123 --json

JSON output

Every command accepts --json. List reads return {"posts": [...], "after": "cursor"} (pass after back via --after to paginate); writes return {"success": true, ...}. Errors return {"error": true, "code": "...", "message": "..."}.

Auth

cli-web-reddit auth login      # opens a Playwright browser, extracts the token_v2 cookie
cli-web-reddit auth status --json
cli-web-reddit auth logout

When token_v2 expires (~15-30 min) the CLI refreshes it silently via a headless browser — no manual re-login. For CI, set CLI_WEB_REDDIT_AUTH_JSON with the cookies JSON. Run doctor to diagnose auth problems.

Utilities

cli-web-reddit doctor [--json] self-diagnoses the local setup (install, auth, dependencies). cli-web-reddit mcp-serve serves the commands as MCP tools over stdio.

Agent tips

• An HTTP 403 on a specific endpoint (e.g. flair fetch on some subreddits) means "permission denied" for that resource, not expired auth.
• Public rate limit is roughly 60 requests/minute — space out scripted reads.
