This installs everything — binary, Swift helpers, FFmpeg, and the BERT model. No compilation required.
Build from Source
git clone https://github.com/bjenkinsgit/psyxe-mcp.git
cd psyxe-mcp
./build.sh
The build script handles everything automatically:
Installs Homebrew, Rust, FFmpeg, and pkg-config if missing
Builds the MCP server binary (Rust)
Builds Swift helpers for Reminders and Contacts
Copies helpers next to the binary
Pre-downloads the BERT model (~90MB) so first search is instant
Build without semantic search (skips FFmpeg and BERT):
./build.sh --no-memvid
Requirements: macOS 12+ (Monterey or later). Xcode Command Line Tools will be prompted if not installed.
The binary and helpers are in target/release/. Use the full path when configuring your MCP client.
Install Apple Shortcuts (optional)
Two shortcuts enable linking Reminders to file artifacts:
./install-shortcuts.sh
This opens each shortcut in Shortcuts.app for you to approve.
Configure Your MCP Client
If you installed via Homebrew, the command is just psyxe-mcp (it's in your PATH). If you built from source, use the full path: /Users/yourname/src/psyxe-mcp/target/release/psyxe-mcp.
Note: If you built from source instead of using Homebrew, replace psyxe-mcp with the full path to the binary (e.g., /Users/yourname/src/psyxe-mcp/target/release/psyxe-mcp).
Access Control
By default, the MCP server has full access to all your Notes, Reminders, Contacts, and files. To restrict what your AI can see, use the built-in access control CLI to create and manage ~/.psyxe/access.toml.
No manual file editing is needed — the CLI creates the file with secure permissions (owner-only read/write) on first use.
Quick Start
# 1. See what's available
psyxe-mcp access discover reminders
psyxe-mcp access discover notes
# 2. Grant access to only what the AI should see
psyxe-mcp access grant reminders "Work"
psyxe-mcp access grant notes "Projects"
# 3. Verify your restrictions
psyxe-mcp access list
Once any rule is set for a category, only explicitly granted resources are accessible — everything else in that category is denied.
Discover What's Available
# See your reminder lists
psyxe-mcp access discover reminders
# See your contact groups
psyxe-mcp access discover contacts
# See your note folders
psyxe-mcp access discover notes
# See common file locations
psyxe-mcp access discover files
Grant / Revoke Access
# Only allow access to specific reminder lists
psyxe-mcp access grant reminders "Work"
psyxe-mcp access grant reminders "Shopping" --rw # read-write
# Only allow access to a specific contact group
psyxe-mcp access grant contacts "iCloud"
# Only allow access to specific note folders
psyxe-mcp access grant notes "Projects"
# Grant file access to a folder
psyxe-mcp access grant files "/Users/you/Documents" --rw
# Revoke access
psyxe-mcp access revoke reminders "Shopping"
# See current restrictions
psyxe-mcp access list
# Remove all restrictions (restore full access)
psyxe-mcp access reset
Access rules are stored in ~/.psyxe/access.toml with owner-only permissions (chmod 600). The server refuses to load the config if it is group- or world-readable, preventing other processes from tampering with access rights.
Semantic Search
When built with the memvid feature (enabled by default), the server includes BERT-powered semantic search for Apple Notes. This uses memvid-rs to encode your notes into a searchable vector index.
First Use
The first time you (or your AI assistant) run a semantic search, the server will build an index of all your notes. This takes a few minutes depending on how many notes you have. Subsequent searches are instant.
# Or ask your AI assistant: "search my notes for machine learning concepts"
# It will automatically build the index on first use.
How It Works
All notes are fetched from Notes.app
Each note is chunked and encoded with a BERT model (384-dimensional embeddings)
Chunks are stored as QR codes in a ProRes video file (compact, durable archive)
A vector index (HNSW) enables instant semantic similarity search
The index auto-detects when notes change and prompts for rebuild
Try It Out
We've included sample notes designed to showcase semantic search:
# Load 10 sample notes into Apple Notes
./examples/load-sample-notes.sh
# Then ask your AI assistant to rebuild the index and try queries like:
# "retirement savings" → finds Tax Strategy (never mentions "retirement")
# "Italian cooking" → finds Carbonara recipe (never says "Italian")
The default model (sentence-transformers/all-MiniLM-L6-v2, 384 dimensions) balances speed and quality. You can swap in any HuggingFace BERT-family sentence-transformer model.
The MCP server is a thin stdio bridge. All the real work happens in psyxe-mcp-core, the open-source library that provides direct access to macOS-native APIs.
Configuration
Semantic Search (memvid)
Place a memvid_config.toml in the working directory or next to the binary:
[chunking]
chunk_size = 700
overlap = 100
[ml]
device = "metal" # auto | cpu | cuda | metal
[qr]
error_correction = "low"
version = 40
[video]
codec = "prores_ks"
prores_profile = "proxy"
library_log_level = "error"
"osascript is not allowed to send keystrokes"
Grant Accessibility permission: System Settings → Privacy & Security → Accessibility
"reminders-helper" wants to access your Reminders
Click Allow. If you previously denied, re-enable in System Settings → Privacy & Security → Reminders.
Semantic search is slow on first run
The BERT model downloads on first use (~90MB). Subsequent runs use the cached model. Index building speed depends on note count — Metal GPU acceleration helps significantly on Apple Silicon.
Notes search returns stale results
The server monitors for changes and will prompt your AI assistant to rebuild the index. You can also force it: ask your assistant to "rebuild the notes index".
