Black Label Plugins MCP Server

Black Label Plugins

Three business-use plugins for Codex and Claude Code. Browser 1.0.2; Presence 1.0.1; Business Site Audit 1.1.2.

• Black Label Browser: control real Safari and Chrome on macOS through Accessibility and native input. No browser extension, CDP, Apple Events or Automator.
• Black Label Presence: coordinate an owner-authorized presence campaign, inspect real content and media, prevent duplicate submissions, and record observed receipts. The executing agent performs browser actions.
• Business Site Audit: audit your own public website for crawl, indexing, metadata and structured-data issues, with observed source URLs and focused fixes. Its declared, hosted MCP tool needs no account or local runtime.

Install

Browser and Presence require macOS 13 or later, Python 3.9+, Apple's Command Line Tools (xcrun swiftc), Safari or Chrome, and a host supporting local stdio MCP plugins. Business Site Audit uses its public HTTPS MCP server and works wherever the plugin host supports remote MCP. Build the browser helper on the target Mac. The helper is locally ad-hoc signed; this release is source, not a notarized binary.

git clone https://github.com/mthburnsbarber-web/black-label-plugins.git
cd black-label-plugins
python3 black-label-browser/install.py

Grant Black Label Browser Bridge Accessibility and Screen Recording through macOS System Settings when needed. Installation does not change permissions. Text-code lookup also needs the Python host's existing permission to read Messages; the helper's Accessibility grant alone does not provide that access.

For Codex:

codex plugin marketplace add https://github.com/mthburnsbarber-web/black-label-plugins.git
codex plugin add black-label-browser@black-label-public
codex plugin add black-label-presence@black-label-public
codex plugin add business-site-audit@black-label-public

For Claude Code:

claude plugin marketplace add https://github.com/mthburnsbarber-web/black-label-plugins.git
claude plugin install black-label-browser@black-label-public --scope user
claude plugin install black-label-presence@black-label-public --scope user
claude plugin install business-site-audit@black-label-public --scope user

Reload plugins or refresh the host's tool context. These are independently hosted public plugins; installation does not imply OpenAI or Anthropic directory approval.

Use

“Audit my business website and show the evidence behind the first fixes.”

Or, with Browser and Presence installed: “Publish one distinct product update with matching real screenshots on our existing LinkedIn and X accounts, finish the requested profile corrections, and give me the verified links.”

The agent discovers the exact authorized identities from the live browser. It retains corrections, inspects content, executes actions and checks results without repeatedly asking for the same instruction. Draft and audit requests remain non-publishing tasks.

The public registry contains 57 destinations, no personal accounts or credentials: 44 active templates, eight held, three excluded and two conditional. Use an explicit site list for a narrow job. To customize destinations, make a private copy of black-label-presence/platforms.json, change requirements/account candidates/dispositions, and configure BL_PRESENCE_REGISTRY in the Presence MCP environment. Never commit that private copy. Registry coverage is not proof of real authentication or site-specific API support.

The browser supports saved sessions and ordinary password autofill. Email verification is a search route executed by the agent, not an inbox reader. Text-code matching uses recent incoming Messages with service/time/sender filtering. Human checks and device approvals require the real user's action; work resumes afterward. Providers may change their UI or restrict accounts.

Verification

python3 -m unittest discover -s black-label-presence/tests -v
python3 -m unittest discover -s black-label-browser/tests -v
python3 black-label-browser/tests/live_native.py
npm --prefix business-site-audit-mcp test
node business-site-audit-mcp/bin/audit-site.mjs https://example.com/

The native browser command opens localhost fixture tabs in Safari and Chrome, changes foreground focus, and tests text entry, submission/readback, screenshots and native file selection. It creates no social posts. The site audit CLI is a maintainer check; buyers use the declared MCP tool. See VERIFICATION.md for exact observed evidence and limits, and PRIVACY.md for data handling.
