Mcp Beeper Texts — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Mcp Beeper Texts (Agent Skill) and scored it 74/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 3 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
A local-only MCP (Model Context Protocol) server tested on macOS that exposes Beeper Texts data (messages, contacts, chats) for use with AI assistants and automation tools. Local-only means the MCP accesses your local Beeper SQLite database only, and does not make or trigger any network requests.
Install from PyPI using pip or uvx:
pip install mcp-beeper-textsOr use uvx for isolated execution:
uvx mcp-beeper-textsAdd the following to your Claude Desktop configuration file (~/Library/Application Support/Claude/claude_desktop_config.json):
{
"mcpServers": {
"beeper": {
"command": "uvx",
"args": ["mcp-beeper-texts"]
}
}
}For other MCP clients, use the command:
uvx mcp-beeper-textsThe server communicates over stdio transport.
Add support for:

uv run pytest tests/ -vUse the MCP Inspector for development and testing:
uv run mcp dev src/mcp_beeper_texts/server.pyFor Claude Desktop testing (or other local MCP clients), use this configuration in ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"Beeper": {
"command": "/opt/homebrew/bin/uv",
"args": [
"run",
"--dev",
"--project",
"/path/to/your/mcp-beeper-texts",
"mcp-beeper-texts"
]
}
}
}Replace /path/to/your/mcp-beeper-texts with the actual path to your local repository.
For faster development with automatic reloading when files change, you can use MCP Reloader:
# Install MCP Reloader (one-time setup)
git clone https://github.com/mizchi/mcp-reloader.git
cd mcp-reloader
npm install
npm run build
# Run with hot-reload (from your project directory)
npx mcp-reloader --command "uv run src/mcp_beeper_texts/server.py"This automatically restarts the server when you modify any Python files, providing a faster development workflow.
The server reads from Beeper's local SQLite databases located at:
~/Library/Application Support/BeeperTexts/
index.db: Beeper UI-optimized message and chat index and metadatalocal-{platform}/megabridge.db: Platform-specific data and contactsThe server only requires read access for most operations, with write access eventually needed for draft management and message sending.
Ensure Beeper Desktop is installed and has been run at least once. The application creates its data directory on first launch.
Make sure Beeper Desktop is properly configured with at least one connected account. The databases are created when platforms are connected.
Ensure the server has read access to ~/Library/Application Support/BeeperTexts/. This should be automatic on macOS.
