An MCP (Model Context Protocol) server plus CLI for fast Buddhist text search and retrieval. Supports CBETA (Chinese), Pāli Tipitaka (romanized), GRETIL (Sanskrit TEI), and SAT (online). Implemented in Rust for speed and reliability.

• Fast regex/content search with line numbers (CBETA/Tipitaka/GRETIL)
• Title search across CBETA, Tipitaka, and GRETIL indices
• Precise context fetching by line number or character range
• Optional SAT online search with smart caching
• One-shot bootstrap and index build

Prerequisite: Git must be installed.

Quick bootstrap:

curl -fsSL https://raw.githubusercontent.com/sinryo/daizo-mcp/main/scripts/bootstrap.sh | bash -s -- --yes --write-path

Manual:

cargo build --release
scripts/install.sh --prefix "$HOME/.daizo" --write-path

Claude Code CLI:

claude mcp add daizo "$HOME/.daizo/bin/daizo-mcp"

Codex CLI (~/.codex/config.toml):

[mcp_servers.daizo]
command = "/Users/you/.daizo/bin/daizo-mcp"

Search:

# Title search
daizo-cli cbeta-title-search --query "楞伽經" --json
daizo-cli tipitaka-title-search --query "dn 1" --json

# Content search (with line numbers)
daizo-cli cbeta-search --query "阿弥陀" --max-results 10
daizo-cli tipitaka-search --query "nibbana|vipassana" --max-results 15
daizo-cli gretil-search --query "yoga" --max-results 10

Fetch:

# Fetch by ID
daizo-cli cbeta-fetch --id T0858 --part 1 --max-chars 4000 --json
daizo-cli tipitaka-fetch --id e0101n.mul --max-chars 2000 --json
daizo-cli gretil-fetch --query "Bhagavadgita" --max-chars 4000 --json

# Context around a line (after search)
daizo-cli cbeta-fetch --id T0858 --line-number 342 --context-before 10 --context-after 200
daizo-cli tipitaka-fetch --id s0305m.mul --line-number 158 --context-before 5 --context-after 100

Admin:

daizo-cli init                      # first-time setup (downloads data, builds indexes)
daizo-cli doctor --verbose          # diagnose install and data
daizo-cli index-rebuild --source all
daizo-cli uninstall --purge         # remove binaries and data/cache
daizo-cli update --yes              # reinstall this CLI

Search:

• cbeta_title_search, cbeta_search
• tipitaka_title_search, tipitaka_search
• gretil_title_search, gretil_search
• sat_search

Fetch:

• cbeta_fetch (supports lineNumber, contextBefore, contextAfter)
• tipitaka_fetch (supports lineNumber, contextBefore, contextAfter)
• gretil_fetch (supports lineNumber, contextBefore, contextAfter)
• sat_fetch, sat_pipeline

• Default flow: *_search → read _meta.fetchSuggestions → call *_fetch with { id, lineNumber, contextBefore:1, contextAfter:3 }.
• Use *_pipeline only when you need a multi-file summary; set autoFetch=false by default. Search tools also provide _meta.pipelineHint.
• Tool descriptions mention these hints; initialize also exposes a prompts.low-token-guide entry for clients.

Tip: Control number of suggestions via DAIZO_HINT_TOP (default 1).
