What is an MCP Server?

An MCP (Model Context Protocol) server is a component that facilitates the ingestion, chunking, semantic search, and management of documents to provide context to AI models (LLMs). It acts as a bridge between AI models and external data sources.

What file types does the MCP Server support for ingestion?

The MCP Server supports Markdown (.md), Python (.py), OpenAPI JSON, and HTML files. It can also ingest HTML content from URLs, optionally using Playwright for dynamic content.

What is semantic search, and how does the MCP Server use it?

Semantic search is a vector-based search method that retrieves information based on meaning and context rather than exact keyword matches. The MCP Server uses semantic search to find the most relevant chunks of ingested content for a given query.

Can I filter search results based on the type of content?

Yes, the search-chunks tool allows you to filter results by chunk type (e.g., code, html, markdown) using the type argument.

How can I add custom metadata to content chunks?

You can use the update-chunk-metadata tool to update the metadata field for a chunk by its ID. The tag-chunks-by-source tool allows adding tags to all chunks from a specific source in one operation.

What is the purpose of chunking?

Chunking divides ingested documents into logical units. This allows AI agents to access precise information without sifting through irrelevant data, optimizing speed and relevance.

What is UBOS and How is MCP server related to it?

UBOS is a Full-stack AI Agent Development Platform that helps businesses orchestrate AI Agents, connect them with enterprise data, build custom AI Agents with LLM model and Multi-Agent Systems. UBOS Asset Marketplace provides the MCP Server for use in context retrieval for AI Agents.

Where I can find Development/Unpublished Servers Configuration for MacOS and Windows?

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

How to debug MCP servers?

For debugging use the MCP Inspector.
