Links Environment

Environment Configuration

  • Location: /opt/mcp-servers/links/mcp_links_server.py
  • Version: 1.1.0 (stable user ID support)
  • Vault Port: 6635 (requires password)
  • Operational Port: 6636 (not replicated)
  • Locker ID: l_a588

Purpose

Hierarchical link/bookmark storage with: - Auto-metadata extraction (title, description, og:image via httpx/BeautifulSoup) - Smart domain categorization (GitHub, Anthropic, AWS, YouTube, etc.) - System > Subsystem hierarchy for organization - Track Pattern: links:{owner}:{timestamp}:link:{hash_id} - Session integration for activity tracking - MD5-based link IDs (8-char hash of URL)

Tools (7 total)

Tool Description Required Params
save Save link with auto-metadata url (required)
save_batch Save multiple links links[] (required)
get Get link by ID link_id (required)
search Search links by query query (required)
list List links by system system, subsystem, limit
systems List all systems with counts none
delete Delete a link link_id (required)
  • url - The saved URL (required)
  • title - Auto-fetched or manual title
  • system - Category (auto or manual)
  • subsystem - Sub-category
  • notes - Free-form notes
  • source - Where link was saved from
  • search_id - Associated search reference

Architecture

Key Pattern

links:{user}:{YYYYMMDD_HHMM}:link:{md5_hash[:8]}

Redis Structure

  • links:{user}:all_links (set) - all link IDs
  • links:{user}:systems (set) - all system names
  • links:{user}:system:{name}:links (set) - links per system
  • links:{user}:system:{name}:subsystem:{sub}:links (set) - links per subsystem

Domain Auto-Categorization

  • github.com → GitHub
  • anthropic.com → Anthropic
  • docs.anthropic.com → Anthropic/Docs
  • youtube.com/youtu.be → YouTube
  • aws.amazon.com → AWS
  • redis.io → Redis
    • many more built-in mappings

Integrations

  • httpx for HTTP requests (10s timeout)
  • BeautifulSoup for HTML parsing
  • session_helper for activity linking
  • user_helper for stable user IDs
  • credentials_helper for passwords

Security Assessment

✅ Uses credentials_helper for password from Locker (l_a588) ✅ No SQL injection (Redis-based) ✅ No command injection vectors ✅ HTTP client has timeout protection (10s) ✅ User-Agent properly identified as bot

⚠️ Hardcoded fallback password: '9MYE06' (line 65) ⚠️ Port 6636 has no data (DBSIZE=0) - not replicated

Current Data

  • Vault (6635): 35 keys
  • Operational (6636): 0 keys
  • Active links: ~20 across 6 systems
  • Systems: GitHub, Anthropic/Docs, ElevenLabs, Redis, Nexus, Docs

Test Results

✅ Redis 6635 (vault): Responding ✅ Redis 6636 (operational): Responding ✅ links.list: Working ✅ links.systems: Working - 6 systems ✅ links.get: Working ✅ links.search: Working

Status: WORKING

Links environment fully operational. Operational port 6636 not replicated (data only on vault 6635).
