PinThePiece

PinThePiece MCP Server provides a structured, reliable note management backend built around a hierarchical storage system with atomic operations, versioning, automatic backups, and robust search capabilities. It is designed to help you store, organize, and retrieve notes efficiently while ensuring data safety and concurrent access handling.

How to use

You connect to the PinThePiece MCP server through an MCP client. Once connected, you can add new notes, update existing ones, summarize all notes, and browse notes using their hierarchical organization and metadata. The system automatically creates backups before modifications, validates data integrity, and exposes a stable URI scheme for note access. Use the client to trigger the available prompts and tools to generate summaries and manage your note collection.

How to install

Prerequisites you need before installing the PinThePiece MCP Server:

• Python installed (recommended) or the environment suitable for running the MCP runtime
• A compatible MCP runtime client (MCP protocol client) available in your environment

Install and run the MCP server using the provided runtime commands for development or published configurations.

Development and runtime configurations

"mcpServers": {
  "pinthepiece": {
    "command": "uv",
    "args": [
      "--directory",

Notes on storage, backups, and data safety

Notes are stored under a hierarchical directory structure to support organization and scalability. The storage layout includes data, backups, and an index, with logs captured for auditing and troubleshooting. All writes are atomic to protect against corruption, and automatic backups are created before modifications. Versioning, checksums, and metadata help ensure data integrity and future compatibility. Concurrency is handled with file locking and transactional-style operations with rollback support.

Prompts

The server provides a single prompt: summarize-notes. You can optionally pass a style argument to control the level of detail (brief or detailed). The prompt combines all current notes into a single summary according to your style preference.

Tools

add-note: Adds a new note to the server. Requires name and content as strings. Optional tags and description. Updates server state and notifies clients of resource changes. Performs atomic file operations with backup creation.

Configuration

Storage Location By default, notes are stored in ~/.pinthepiece/notes/ and logs are stored in ~/.pinthepiece/logs/.

Logging Includes detailed operation logs with log rotation and the option for both file and console outputs. Log levels are configurable.

Security and reliability notes

The server emphasizes data safety with atomic file operations, automatic backups, versioned data formats, integrity checks, and explicit rollback capabilities to recover from interrupted operations.
