Which integrations are available for this server?

Integrates with Obsidian vaults to provide semantic search, entity extraction, and knowledge graph capabilities for AI coding assistants.

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Cortex remind me about the forgetting curve design" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

🧠 Cortex — Proactive Memory Agent for AI Coding Assistants

Obsidian-backed knowledge graph with semantic search, entity extraction, and cross-session memory. 11 MCP tools. Works with Claude Code, Cursor, Windsurf, and any MCP-compatible editor.

What It Does

You: "How does the memory system handle forgetting?"
Cortex: 💡 This reminds me of your previous work on:
       1. decisions/memory-architecture-choice — Ebbinghaus decay with 14-day half-life
       2. daily/2026-06-19 — You designed the three-tier memory architecture
       3. moc/system-architecture — Full system diagram

Semantic search — Find concepts across languages (EN query → CN content)
Knowledge graph — 928 entities, 106K relationships, auto-extracted from your notes
Proactive context — memory_monitor watches conversation topics, surfaces relevant memories
Gap analysis — Compare your learning goals against actual knowledge coverage
Cross-session — Every session loads your memory index + recent daily logs automatically

Quick Start

# 1. Install
cd Cortex/mcp-server
npm install --ignore-scripts
npx tsc

# 2. Configure (Claude Code)
# Copy the MCP config to your global Claude Code settings:
# ~/.claude/.mcp.json

# 3. Use
# Start a Claude Code session. The MCP server starts automatically.
# Say: "memory_ingest" to index your vault
# Say: "search for architecture decisions" to find memories

MCP Tools

Tool	Description
`memory_search`	Hybrid keyword + vector semantic search
`memory_ingest`	Scan vault, extract entities, build index
`memory_status`	System health report
`memory_entity_extract`	Extract typed entities from text
`memory_graph_query`	Query the knowledge graph (multi-hop)
`memory_auto_link`	Suggest `[[wikilinks]]` between notes
`memory_monitor`	Process conversation, return proactive context
`memory_conflict_resolve`	Detect contradictions with existing memories
`memory_gap_analysis`	Analyze knowledge gaps vs learning goals
`memory_consolidate`	Apply decay, find archive candidates
`memory_session_end`	Generate daily note (portable Stop hook)

Editor Support

Editor	Setup
Claude Code	`~/.claude/.mcp.json` (global) or `.mcp.json` (project)
Cursor	Copy `editors/cursor.mcp.json` → `.cursor/mcp.json`
