Getting Started

Installation

Install Content Core using pip - no system dependencies required!

# Basic installation (PyMuPDF + BeautifulSoup/Jina extraction)
pip install content-core

# With enhanced document processing (adds Docling)
pip install content-core[docling]

# With local browser-based URL extraction (adds Crawl4AI)
# Note: Requires Playwright browsers (~300MB). Run:
pip install content-core[crawl4ai]
python -m playwright install --with-deps

# Full installation (with all optional features)
pip install content-core[docling,crawl4ai]

Note: The core installation uses pure Python implementations and doesn't require system libraries like libmagic, ensuring consistent, hassle-free installation across Windows, macOS, and Linux. Optional features like Crawl4AI (browser automation) may require additional system dependencies.

Alternatively, if you’re developing locally:

# Clone the repository
git clone https://github.com/lfnovo/content-core
cd content-core

# Install with uv
uv sync

Command-Line Interface

Content Core provides three CLI commands for extracting, cleaning, and summarizing content: ccore, cclean, and csum. These commands support input from text, URLs, files, or piped data (e.g., via cat file | command).

Zero-install usage with uvx:

# Extract content
uvx --from "content-core" ccore https://example.com

# Clean content  
uvx --from "content-core" cclean "messy content"

# Summarize content
uvx --from "content-core" csum "long text" --context "bullet points"

ccore - Extract Content

Extracts content from text, URLs, or files, with optional formatting. Usage:

ccore [-f|--format xml|json|text] [-d|--debug] [content]

Options:

  • -f, --format: Output format (xml, json, or text). Default: text.
  • -d, --debug: Enable debug logging.
  • content: Input content (text, URL, or file path). If omitted, reads from stdin.

Examples:

# Extract from a URL as text
ccore https://example.com

# Extract from a file as JSON
ccore -f json document.pdf

# Extract from piped text as XML
echo "Sample text" | ccore --format xml

cclean - Clean Content

Cleans content by removing unnecessary formatting, spaces, or artifacts. Accepts text, JSON, XML input, URLs, or file paths. Usage:

cclean [-d|--debug] [content]

Options:

  • -d, --debug: Enable debug logging.
  • content: Input content to clean (text, URL, file path, JSON, or XML). If omitted, reads from stdin.

Examples:

# Clean a text string
cclean "  messy   text   "

# Clean piped JSON
echo '{"content": "  messy   text   "}' | cclean

# Clean content from a URL
cclean https://example.com

# Clean a file’s content
cclean document.txt

csum - Summarize Content

Summarizes content with an optional context to guide the summary style. Accepts text, JSON, XML input, URLs, or file paths.

Usage:

csum [--context "context text"] [-d|--debug] [content]

Options:

  • --context: Context for summarization (e.g., "explain to a child"). Default: none.
  • -d, --debug: Enable debug logging.
  • content: Input content to summarize (text, URL, file path, JSON, or XML). If omitted, reads from stdin.

Examples:

# Summarize text
csum "AI is transforming industries."

# Summarize with context
csum --context "in bullet points" "AI is transforming industries."

# Summarize piped content
cat article.txt | csum --context "one sentence"

# Summarize content from URL
csum https://example.com

# Summarize a file's content
csum document.txt

Quick Start

You can quickly integrate content-core into your Python projects to extract, clean, and summarize content from various sources.

import content_core as cc

# Extract content from a URL, file, or text
result = await cc.extract("https://example.com/article")

# Clean messy content
cleaned_text = await cc.clean("...messy text with [brackets] and extra spaces...")

# Summarize content with optional context
summary = await cc.summarize_content("long article text", context="explain to a child")

# Extract audio with custom speech-to-text model
from content_core.common import ProcessSourceInput
result = await cc.extract(ProcessSourceInput(
    file_path="interview.mp3",
    audio_provider="openai",
    audio_model="whisper-1"
))

FAQ

What is the Content Core MCP server?
Content Core is a Model Context Protocol (MCP) server profile on explainx.ai. MCP lets AI hosts (e.g. Claude Desktop, Cursor) call tools and resources through a standard interface; this page summarizes categories, install hints, and community ratings.
How do MCP servers relate to agent skills?
Skills are reusable instruction packages (often SKILL.md); MCP servers expose live capabilities. Teams frequently combine both—skills for workflows, MCP for APIs and data. See explainx.ai/skills and explainx.ai/mcp-servers for parallel directories.
How are reviews shown for Content Core?
This profile displays 44 aggregated ratings (sample rows for discoverability plus signed-in user reviews). Average score is about 4.7 out of 5—verify behavior in your own environment before production use.

✗ Don't

  • Don't grant overly permissive access to MCP servers
  • Don't skip reading security considerations in docs
  • Don't expose sensitive data without proper controls
  • Don't run untrusted MCP servers without code review
  • Don't ignore error messages—investigate root cause

💡 Pro Tips

  • Combine multiple MCP servers for powerful workflows

Technical Details

Architecture

Model Context Protocol standardizes how AI hosts (Claude, Cursor) communicate with external tools and data sources through server implementations.

Protocols

  • Model Context Protocol (MCP)
  • JSON-RPC 2.0
  • stdio or HTTP transport

Compatibility

  • Claude Desktop
  • Cursor IDE
  • Custom MCP clients

When to Use This

✓ Use When

Use when you need Claude to access external data, execute actions, or integrate with tools. Best for extending AI capabilities beyond conversation.

✗ Avoid When

Avoid when native integrations exist (use official APIs directly), for real-time critical systems, or when security/compliance requires zero external dependencies.

Integration

  • Tool composition: Chain multiple MCP tools in workflows
  • Context augmentation: Provide AI with relevant external data
  • Action delegation: Let AI execute tasks on external systems
  • Bidirectional sync: Keep AI context and external systems in sync
