Question 1

What is an MCP Server?

Accepted Answer

MCP (Model Context Protocol) is an open protocol that standardizes how applications provide context to LLMs. An MCP server acts as a bridge, allowing AI models to access and interact with external data sources and tools.

Question 2

What is the UBOS Asset Marketplace?

Accepted Answer

The UBOS Asset Marketplace is a platform where developers can share and discover reusable components, like the MCP News Server, to accelerate AI Agent development.

Question 3

What categories of news articles are available?

Accepted Answer

The server provides articles categorized into tech, data_science, llm_tools, cybersecurity, linux, audio_dsp, startups, news, science, research, and policy.

Question 4

How do I access news articles using the MCP News Server?

Accepted Answer

You can access articles using the resource URI: news://{category}/{limit}, where {category} is the desired news category and {limit} is the maximum number of articles to return.

Question 5

How do I configure the MCP News Server?

Accepted Answer

Configuration is done through environment variables, such as DATABASE_URL for the PostgreSQL database connection and OPENAI_API_KEY for summarization logic. Other configurations include LOOKBACK_HOURS, SUMMARY_WORD_TARGET, MAX_ARTICLES_PER_SUMMARY, and KEYWORD_FILTER.

Question 6

How do I populate the database with news articles?

Accepted Answer

Run the news_gatherer.py script, which collects news articles from various RSS feeds and stores them in the database. This script is intended to be run separately/scheduled.

Question 7

Does the server summarize news articles?

Accepted Answer

The server has internal summarization logic, but it is currently not exposed via an MCP prompt. The summarize_news tool retrieves raw articles, allowing client LLMs to perform summarization.

Question 8

How can I debug the MCP News Server?

Accepted Answer

The MCP Inspector is strongly recommended for debugging, as MCP servers run over stdio. You can launch it using npx @modelcontextprotocol/inspector uv --directory ~/dev/news-mcp run news-mcp.

Question 9

How do I install the MCP News Server for development?

Accepted Answer

Configure your Claude Desktop's claude_desktop_config.json file to point to your local development directory. Refer to the documentation for specific examples for development/unpublished and published server configurations.

Question 10

How do I contribute to the MCP News Server project?

Accepted Answer

Contributions are welcome! Follow the development process, including syncing dependencies, building packages, and publishing to PyPI. See the development section in the documentation for details.
