🏠 tilde

Your AI agents' home directory

tilde is a privacy-first Model Context Protocol (MCP) server that acts as the universal memory and profile layer for AI Agents.

Configure once. Use everywhere. Your data, your control.

Supports profile management, skills, resume import, and team sync.

The Problem

Every time you switch AI tools, you face the same issues:

• 🔄 Repetition: "I'm a Senior SWE", "I prefer Python", "Don't use ORMs"
• 🧩 Fragmentation: Preferences learned in Cursor aren't available in Claude
• 🔒 Privacy Concerns: Unsure who has access to your personal context

The Solution

tilde acts as a "digital passport" that your AI agents can read:

┌────────────────────────────────────────────────────────────┐
│  Claude Desktop  │   Cursor   │  Windsurf  │  Your Agent   │
└────────┬─────────┴─────┬──────┴─────┬──────┴───────┬───────┘
         │               │            │              │
         └───────────────┴─────┬──────┴──────────────┘
                               │
                    ┌──────────▼──────────┐
                    │   tilde MCP Server  │
                    │   (runs locally)    │
                    └──────────┬──────────┘
                               │
                    ┌──────────▼──────────┐
                    │   ~/.tilde/profile  │
                    │   (your data)       │
                    └─────────────────────┘

Quick Start

Installation

# Install from PyPI
pip install tilde-ai

# Initialize your profile
tilde init

Development Installation

# Clone the repository
git clone https://github.com/topskychen/tilde.git
cd tilde

# Install with uv
uv sync

# Run locally
uv run tilde init

Configure Cursor

Add to .cursor/mcp.json in your project (or ~/.cursor/mcp.json for global access):

{
  "mcpServers": {
    "tilde": {
      "command": "npx",
      "args": ["-y", "tilde-ai"]
    }
  }
}

Once configured, you'll see tilde in your MCP servers with all available tools and resources:

Configure Antigravity

Add to .gemini/antigravity/settings.json in your project:

{
  "mcpServers": {
    "tilde": {
      "command": "npx",
      "args": ["-y", "tilde-ai"]
    }
  }
}

Configure Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

Example Usage

Once configured, your AI agent can access your profile. Try asking:

"What is my name?"

The agent will use the get_profile tool to fetch your identity and respond with your name and role:

Document Ingestion

# Ingest a book and extract insights
tilde ingest "~/Books/DDIA.pdf" --topic data_systems

# Dry run to preview what would be extracted
tilde ingest notes.md --dry-run

# Auto-approve high-confidence updates
tilde ingest paper.pdf --auto-approve 0.8

Resume Import

Bootstrap your profile from an existing resume:

# Import resume (PDF, DOCX, or text)
tilde ingest ~/Documents/resume.pdf --type resume

# Preview what would be extracted
tilde ingest resume.pdf --type resume --dry-run

# Auto-approve high-confidence items
tilde ingest resume.pdf --type resume --auto-approve 0.8

The resume importer extracts:

• Identity: Name, role, years of experience
• Experience: Work history with companies, roles, dates
• Education: Degrees, institutions, graduation years
• Tech Stack: Programming languages, frameworks, tools
• Projects: Personal and open-source projects
• Publications: Papers, patents, articles

Skills Management

Manage Anthropic-format skills with full bundling support:

# Import skills from Anthropic skills directory
tilde skills import /path/to/skills

# Import specific skills by name
tilde skills import /path/to/skills -n mcp-builder -n pdf

# Dry run to preview import
tilde skills import ./skills --dry-run

# Import as private skills
tilde skills import ./skills --visibility private

# List all imported skills
tilde skills list

# Export skills to Anthropic format
tilde skills export ./my-skills

# Export specific skill
tilde skills export ./output -n mcp-builder

# Delete skills
tilde skills delete skill-name
tilde skills delete --all --force

The skill importer bundles:

• SKILL.md: Skill content with YAML frontmatter
• scripts/: Python scripts and utilities
• references/: Documentation files
• templates/: Template files
• assets/: Static assets
• Root files: LICENSE.txt, etc.

All bundled resources are preserved through import → persist → export.

Team Management

# Create a team
tilde team create myteam --name "My Startup" --org "ACME Corp"

# Activate team context (applies to all profile queries)
tilde team activate myteam

# Sync team config from URL or git repo
tilde team sync https://example.com/team.json --activate
tilde team sync git@github.com:myorg/team-config.git --activate

# List and manage teams
tilde team list
tilde team show
tilde team edit
tilde team deactivate

Storage Backends

tilde supports multiple storage backends:

Backend	Use Case	Command
YAML (default)	Human-readable, git-friendly	TILDE_STORAGE=yaml
SQLite	Queryable, memories, faster at scale	TILDE_STORAGE=sqlite
Mem0	Semantic search via embeddings	TILDE_STORAGE=mem0

# Use SQLite backend
export TILDE_STORAGE=sqlite
tilde init

# Query profile fields (SQLite only)
uv run python -c "
from tilde.storage import get_storage
storage = get_storage(backend='sqlite')
print(storage.query('%languages%'))
"

---

Configuration

tilde uses a centralized configuration for LLM and embedding settings. Configuration is stored in ~/.tilde/config.yaml and can be synced across devices.

Configuration Priority

1. Environment variables (highest priority)
2. Config file (~/.tilde/config.yaml)
3. Built-in defaults (lowest priority)

Environment Variables

Variable	Description	Default
GOOGLE_API_KEY	Google/Gemini API key (primary)	Required
OPENAI_API_KEY	OpenAI API key (fallback)	Optional
TILDE_LLM_MODEL	LLM model for document ingestion	gemini-3-flash-preview
TILDE_EMBEDDING_MODEL	Embedding model for semantic search	gemini-embedding-001
TILDE_STORAGE	Storage backend (yaml, sqlite, mem0)	yaml
TILDE_PROFILE	Custom profile path	~/.tilde/profile.yaml

Managing Configuration

# View current configuration
tilde config

# Save settings to config file (for syncing across devices)
tilde config --save

# Modify a setting and save
tilde config --set llm_model=gemini-1.5-pro

# Show config file path
tilde config --path

Note: API keys are NEVER saved to the config file for security. Always set them via environment variables.

Quick Setup

# Minimal setup (just one API key!)
export GOOGLE_API_KEY="your-google-api-key"

# Save your settings for this device
tilde config --save

# Now you can use all features
tilde ingest paper.pdf

Syncing Across Devices

The config file at ~/.tilde/config.yaml is designed to be synced:

1. Via dotfiles repo: Add ~/.tilde/ to your dotfiles
2. Via cloud sync: Dropbox, iCloud, or similar
3. Manually: Copy the file to new devices

Example config file:

llm_model: gemini-3-flash-preview
llm_temperature: 0.7
embedding_model: gemini-embedding-001
embedding_dimensions: 768
storage_backend: yaml

Programmatic Configuration

from tilde.config import get_config, call_llm, get_embedding, save_config

# Check current config
config = get_config()
print(f"Provider: {config.provider}")
print(f"LLM Model: {config.llm_model}")

# Use directly
response = call_llm("Summarize this document...")
embedding = get_embedding("Some text to embed")

Roadmap

• Phase 1: MVP with profile reading
• Phase 2: Agent-proposed updates with approval flow
• Phase 3: Document ingestion (books, PDFs)
• Phase 4: Team sync for B2B use cases
• Phase 5: SQLite and Mem0 storage backends
• Phase 6: Skill Management (Anthropic SKILL.md format)
  • Batch import from directory with tilde skills import
  • Export to directory with tilde skills export
  • Full bundling of scripts, references, templates, assets
  • Deduplication by skill name

Why "tilde"?

In Unix, ~ (tilde) represents your home directory — the place where your personal configuration lives. tilde is the home for your AI identity.

---

Philosophy

1. Your Data, Your Control: Local by default, sync only if you choose
2. Human-in-the-Loop: Agents propose, humans decide
3. Portable & Open: Export anytime, no lock-in, works with any MCP tool
4. Progressive Disclosure: Start simple, add complexity as needed
