What is mcp-beeper-texts CLAUDE.md?

Development instructions for mcp-beeper-texts, a local macOS server that lets AI assistants and automation read Beeper Texts messages, contacts, and chats. MCP is a standard way for tools to provide data to an AI assistant.

It is for setting up the Python project, running its development server, testing and formatting the code, building the package, and understanding its SQLite data.

It gives developers the project layout, database location, setup details, and routine commands needed to work on the server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01165	$0.01165
Opus 5.5	$0.00466	$0.00466

Security

Grade A, and why

mcp-beeper-texts CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Beeper Texts MCP Server (mcp-beeper-texts) - Claude Development Guide

This document provides essential information for developing the mcp-beeper-texts server with assistance from Claude.

1. Project Overview

Name: mcp-beeper-texts
Description: A local-only MCP server for macOS that exposes Beeper Texts data (messages, contacts, chats) for use with AI assistants and automation tools.
Technology Stack: Python, mcp SDK, uv, SQLite.
Transport: stdio (Standard I/O).

2. Developer Environment Setup (macOS)

Locate Beeper Database Path:
- The server needs read/write access to the Beeper application support directory. The default path is: ~/Library/Application Support/BeeperTexts/
- The server will attempt to find this path automatically. Knowing its location is crucial for debugging.

3. Common Commands

Run the server for development (with MCP Inspector):

# This command assumes a console script is configured in pyproject.toml
uv run mcp dev mcp-beeper-texts

Run tests:
```
uv run pytest
```

Lint and format code:

uv run ruff check . --fix
uv run ruff format .

Build the package for PyPI:
```
uv run python -m build
```

4. Core Files & Architecture

The project follows a standard src layout for packaging and distribution.

src/mcp_beeper_texts/: The main Python package directory. All installable source code lives here.
- server.py: The core of the application. It defines the FastMCP server, registers all the tools (e.g., list_chats, send_message), and contains the main entry point.
- db.py Contains utility functions for connecting to the Beeper SQLite databases.
- queries.py Holds SQL query strings and data access logic.
- models.py Defines Pydantic models for API responses (e.g., Chat, Message, Contact).
tests/ contains unit and integration tests.
pyproject.toml: Defines project metadata, dependencies, scripts, and build configuration for PyPI.
README.md: Public-facing documentation for the package.
docs/beeper-texts-schema.md: Detailed description of the Beeper Texts database architecture.
docs/mcp-full-docs.md: The most comprehensive MCP documentation with all APIs, best practices, and examples.
docs/mcp-sdk-readme.md: README from the MCP Python SDK.
