Summary
Retrieval instead of upload, for a corpus bigger than the window.
The author's own reason is the useful one: a long-running blog does not fit in a context window, and even if it did, the weaker half is not worth including. Tag and date retrieval let you pull the fifty posts that bear on a question and discuss those.
What it is
An MCP server over folders of Markdown files whose front matter carries title, tags and url, such as a personal blog or a set of notes. It retrieves the relevant posts into the context window instead of uploading the whole corpus.
What you get
- Content retrieved by tag, in batches you choose (get_by_tag)
- The corpus searched for specific text (get_by_text)
- A post found by slug or URL (get_by_slug_or_url)
- Everything published inside a date range (get_by_date_range)
- The tag vocabulary navigated: tags matching a query, or all tags sorted by post count and recency (search_tags, list_all_tags)
- Several separate knowledge bases used together
Requirements
Uv, and a local folder of .md files whose front matter carries title, tags and url. The setup documented is a clone run under Claude Desktop on macOS.
