Knowledge Base MCP Server

Enterprise knowledge base for ADK-Rust Enterprise agents. 9 MCP tools for articles, TF-IDF search boosted by helpfulness, feedback loops, gap detection, versioning, and draft/publish workflow.

Architecture

What It Does

Your agent resolves issues from knowledge before creating tickets. The KB gets smarter over time — helpful articles rank higher, and gaps (queries with no results) tell you what articles to write next.

Tools (9)

| Tool | What It Does | Use Case | |------|-------------|----------| | search_articles | TF-IDF search boosted by helpfulness | "Find articles about VPN" | | get_article | Full article with body, stats, version | "Show me KB-001" | | list_related_articles | Related by tags/category | "What else is related?" | | create_article_draft | Create new draft | "Write an article about X" | | publish_article | Make draft searchable | "Publish this article" | | suggest_article_update | Update existing (new version) | "Update this article" | | record_article_feedback | Helpful/not helpful + comment | "This was helpful" | | list_articles | Browse by category/status | "Show all Network articles" | | get_article_gaps | Queries with no results | "What articles are missing?" |

How It Gets Smarter

1. Feedback boosts ranking — articles marked "helpful" score higher in search
2. Gap detection — every failed search is tracked. Gaps show what to write next.
3. View counting — popular articles surface naturally
4. Versioning — every update creates a new version

Verified Output

> search_articles(query: "password reset")
  1 result: "How to reset your password" (score: 8.3, helpful: 1)

> search_articles(query: "printer not working")
  0 results (gap tracked)

> get_article_gaps()
  1 gap: "printer not working" (searched 1x)

> record_article_feedback(article_id: "KB-001", helpful: true)
  recorded: true (boosts future search ranking)

Installation

cargo install mcp-knowledge-base

MCP client config

{ "mcpServers": { "kb": { "command": "/path/to/mcp-knowledge-base" } } }

Integration with ITSM

The ITSM MCP's handle_support_request can use this KB for resolution:

1. User reports issue → ITSM searches KB
2. KB returns relevant article → issue resolved without ticket
3. No result → gap tracked → team writes new article
