## Description

Writer Context Tool provides a Python-based MCP server that enables Claude to access and search through a writer's content from Substack and Medium blogs. The implementation uses RSS feeds to scrape blog posts, stores them in a persistent disk cache, and generates embeddings for semantic search capabilities. It exposes tools for refreshing content and searching writing by topic, while also providing individual essays as resources that Claude can access directly. Built with asyncio, sentence-transformers, and diskcache, it's designed for writers who want Claude to reference their published work during conversations, with support for customizable caching duration and similarity thresholds.
