### Description (declared)

# chapter-mcp

`chapter-mcp` gives coding agents a compact way to search a project by useful
sections instead of opening whole files.

It indexes a workspace locally, splits files into "chapters", and exposes MCP
tools for searching, listing, and reading those chapters. The goal is simple:
help an assistant find the right part of a repo before it burns context on raw
file reads.

It is intentionally boring in a good way: local SQLite FTS5, deterministic
full-text search, no embeddings, no vector database, and no external service.

## What it is good for

Use `chapter-mcp` when an assistant needs project context but does not yet know
which file or section matters. Good fits:

- project README sections
- `AGENTS.md`, `CLAUDE.md`, instructions, and local notes
- ADRs and design docs
- Markdown/TXT documentation
- source files where top-level classes or functions make useful chapters
- focused reads after a search result points to the right line range

Not a good fit:

- exact code matching with punctuation, operators, routes, or config keys
- symbol references, definitions, diagnostics, or safe edits
- fuzzy semantic search across very different wording

For those, keep using the sharper tool: `rg` for exact text, Serena or another
language-aware tool for symbols, raw file reads for known ranges, and
vector/RAG tooling for real semantic retrieval.

## How chapters work

`chapter-mcp` turns files into smaller units: Markdown by headings, Python by
top-level classes/functions, and other text files by paragraphs. Search results
point to chapter names and line ranges. Reads can return a whole chapter or a
limited slice of chapter content.

By default, if no explicit config is provided, `chapter-mcp` discovers visible
top-level project entries and indexes them. In a Git repo it uses tracked files,
skips hidden top-level entries and `.chapter-mcp`, respects `.gitignore`, and
applies `.aiignore` rules.

That means the happy path is: add the MCP server to your assistant, star…
