Know Your Project — Persistent knowledge base for AI agents. MCP-powered with wikilinks, backlinks, auto-learning, and neon web UI.

KYP-MEM

Claude that remembers your conversations AND understands your project.

KYP-MEM gives AI coding agents two-layer memory:

• Session Memory (Episodic) → remembers what happened across coding sessions

• Project Intelligence → understands architecture, decisions, docs, and relationships

Your AI agent stops starting from zero every day.

Example

User:

"Why did we move from REST to Kafka?"

Claude:

"In the May 12 session, we found the REST pipeline couldn't handle peak trading volume. We decided to migrate to Kafka for async processing. See [[Architecture Decisions]] and [[Event Pipeline]]."

By intercepting the prompt, KYP-MEM automatically provided the agent with:

• The vectorized semantic search results of past session logs.
• The relevant markdown files from the project knowledge base.

How It Works

KYP-MEM operates as a Model Context Protocol (MCP) server that runs silently in the background, integrating directly with Claude Code.

1. Episodic Memory (Sessions)

Every coding session is automatically captured with full context:

• User prompts (what was asked)
• File reads with content (what was found)
• File edits with diffs (what changed and why)
• Command outputs (what happened)

At session end, Claude Sonnet synthesizes raw activity into a structured summary with Summary, Investigated, Learned, Completed, and Next Steps sections. Sessions are semantically searchable via ChromaDB vector embeddings.

2. Project Intelligence (Vault)

KYP-MEM maintains structured project knowledge as Markdown files with [[wikilinks]]:

• Architecture docs, API references, setup guides
• Known issues, decision history, linked concepts

The agent searches this on-demand via kyp_search when it needs project context.

How It All Connects

1. Session Start: Recent session summaries are injected automatically — the agent knows what happened last time.
2. During Work: Hooks capture tool activity (reads, edits, commands) with actual content, not just file names.
3. Session End: Sonnet synthesizes a rich, semantic summary and saves it to the vault + vector DB.
4. Future Sessions: The agent can search past sessions semantically or look up project knowledge on demand.

Installation

npm install -g kyp-mem

That's it. The postinstall script automatically:

1. Installs the Python package
2. Creates the default vault at ~/.kyp-mem/vault
3. Registers the MCP server with Claude Code
4. Installs session capture hooks

Restart Claude Code and you're ready to go.

Requirements

• Node.js 18+
• Python 3.10+
• Claude Code CLI
• Anthropic API key (for session summarization with Sonnet)

Custom Vault Path

If you want to store your vault somewhere other than ~/.kyp-mem/vault:

kyp-mem init    # Interactive prompt to choose vault location

The Agent's Workflow

KYP-MEM embeds behavioral instructions directly into its tools. Without any prompting from you, the agent will automatically:

1. Load Context: On session start, it loads recent session summaries so it knows what happened last time.
2. Search Before Acting: Before investigating bugs or making decisions, it searches past sessions to avoid repeating work.
3. Persist Knowledge: After fixing a bug or making a decision, it updates the project's knowledge base for future sessions.

Web UI

Browse your knowledge graph, view session timelines, and see semantic relationships visually.
