What it can do
Tool names and descriptions exactly as the server reported them on Nov 13, 2026. The maker wrote them, not us; we show them as plain text.
search_corpusSemantic search across fojin's Buddhist corpus (10K+ texts, 30+ langs). Returns the most relevant passages, each with a `urn`, title, snippet and similarity score. `lang` optionally filters by language code (lzh=Classical Chinese, pi=Pali, sa=Sanskrit, bo=Tibetan, en=English).
read_passageRead the full content of one fascicle (卷) of a text, with its `urn`. Use the `text_id`/`juan_num` from a search_corpus hit. Returns the actual canonical text — quote from this, not from memory.
get_parallelsCross-canon parallel passages aligned to a fascicle. fojin's alignment moat: given a Chinese fascicle, returns the aligned Pali/Tibetan/Sanskrit parallels so you can compare how a passage is rendered across traditions. A fascicle returns parallels for the *whole* juan — often hun
lookup_dictionaryLook up a Buddhist term across fojin's dictionaries (748K+ entries).
lookup_entitySearch fojin's knowledge graph for entities — people, places, works, doctrinal terms — matching `query`.
resolve_urnResolve a fojin URN (e.g. fojin:cbeta/T0001.1) to a reader URL and confirm it exists in the corpus. Use to verify or dereference a citation.
verify_quoteVerify that a Buddhist-canon quote exists VERBATIM in the corpus. Call this before presenting any quoted scripture to a reader: LLMs routinely invent plausible-looking quotes. Returns `verbatim` (bool), where it was found (`matches`, each with a resolvable `urn`), or the closest
commentariesWhat the historical commentators said about a passage of Buddhist scripture. Give a line of a sūtra and get back the classical commentaries that gloss it — each with the commentator's own words, the work it comes from, a quality tier, and a resolvable citation. This is the layer

Common questions
Is fojin — Buddhist Canon Tools safe?
It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 2 days ago, and the latest version (0.4.0) reached the registry 3 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

FoJin 佛津
Ask the Buddhist canon — get cited, verifiable answers.
AI Q&A grounded in the world's largest open aggregation of Buddhist texts: 600+ sources, 30+ languages, trilingual cross-canon retrieval — every answer linked back to its source passage.
Ask a question in plain language and FoJin's assistant "XiaoJin" answers from the canon itself — Retrieval-Augmented Generation over 670K+ embedded passages, optional cross-encoder reranking and root-sutra recall, clickable 【《sutra》juan N】 citations that open the exact source text, anti-hallucination guards, and a citation drawer with side-by-side 汉 / 巴利 / 藏文 cross-canon parallels. You can also ask in the voice of 15 historical Buddhist masters, each scoped to their own tradition's scriptures.
What makes those answers trustworthy is the corpus underneath. FoJin aggregates 612 data sources into one searchable platform — 10,500+ texts with 19,000+ volumes of full content in Classical Chinese, Pali, Tibetan and Sanskrit, the first LLM-driven trilingual cross-canon parallel reading platform (CBETA × SuttaCentral × 84000) with LLM-verified chunk-level alignment, a 110K+ entity knowledge graph on a Deck.GL geo map, and 39 dictionaries with 747K entries. Every feature exists to make the answers more grounded — and to let you go deeper once you have one.
FoJin is built to be open, cross-canon, verifiable Buddhist knowledge infrastructure — not just a site to read, but a corpus other tools can *call*. Every passage carries a stable, resolvable cross-canon URN (fojin:cbeta/T0001.1), and the [`fojin-mcp`](https://pypi.org/project/fojin-mcp/) server lets AI assistants (Claude, ChatGPT, any MCP client) answer from FoJin's cited passages directly — hosted at `mcp.fojin.ai`, anonymous, no key required. Any model can also check its own work through the open [`/api/verify/quote`](https://fojin.app/agents) endpoint: hand it a sentence and a citation, and it answers *is this quote real* and *is the citation right* as two separate questions. See [fojin.app/agents](https://fojin.app/agents).

Why FoJin?
Buddhist texts are scattered across hundreds of databases worldwide — CBETA, SuttaCentral, BDRC, SAT, 84000, GRETIL, and many more. Each has its own interface, language, and data format. When you have a *question* — "what does the Heart Sutra mean by 'form is emptiness'?", "how do the Pali and Chinese versions of this passage differ?" — you spend more time hunting for the right passage than understanding it.
FoJin answers the question for you. Ask in plain language; XiaoJin retrieves the relevant passages from 612 sources and answers with clickable citations you can verify. Everything else FoJin does — full-text reading, cross-canon alignment, the knowledge graph, 39 dictionaries — exists to make those answers more grounded, and to let you go deeper once you have one:

Quick Start
git clone https://github.com/xr843/fojin.gitcd fojin cp .env.example .env # edit POSTGRES_PASSWORD before starting docker compose up -d # database migrations run automatically
Then visit: http://localhost:3000
API docs at http://localhost:8000/docs
After first startup, the platform has the database schema and source metadata but no text content. To import texts from public data sources:
# Import CBETA catalog (auto-scans local xml-p5 directory or fetches from remote)docker exec fojin-backend python scripts/import_catalog.py
Import CBETA full text content (requires xml-p5 repository)
docker exec fojin-backend python scripts/import_content.py --all --xml-dir /data/xml-p5
Generate embeddings for AI Q&A (supports incremental processing)
docker exec fojin-backend python -m scripts.archive.misc.generate_embeddings --source cbeta
Import SuttaCentral Early Buddhist Texts
docker exec fojin-backend python scripts/archive/imports/import_suttacentral.py
See all available importers (one-off importers live under archive/)
ls backend/scripts/archive/imports/
Each importer downloads data directly from the original source (CBETA, SuttaCentral, etc.) — no data is bundled in this repository.
Use FoJin from your AI tools (MCP)
FoJin's verified, cross-canon corpus is callable directly from AI assistants (Claude Desktop, ChatGPT, or any MCP client) via the published [`fojin-mcp`](https://pypi.org/project/fojin-mcp/) server — so the assistant answers Buddhist questions from FoJin's cited passages instead of hallucinating.
Point any MCP client at the hosted endpoint — nothing to install, no key to get:
claude mcp add --transport http fojin https://mcp.fojin.ai/mcpOr run it locally over stdio against your own instance:
uvx fojin-mcp # zero-install runor: pip install fojin-mcp && fojin-mcp
It exposes eight read-only tools over the public API, each returning passages with a stable, resolvable cross-canon URN (fojin:cbeta/T0001.1):
| Tool | What it does |
|---|---|
search_corpus | Semantic search across the aggregated canon |
read_passage | Read a specific text / volume |
get_parallels | Cross-canon parallels (汉 ↔ 巴利 ↔ 藏) for a passage |
lookup_dictionary | Term lookup across 39 dictionaries |
lookup_entity | Knowledge-graph entity facts |
resolve_urn | Resolve a FoJin URN to its source location |
verify_quote | Verbatim check — is this sentence really in the canon, and really where you said? Answers "is the quote real" and "is the citation right" separately, with a character-level diff when it is close but not exact |
commentaries | For one passage, what the historical commentators wrote on it — anchored to juan and line |
Claude Desktop config and ChatGPT setup are in [`mcp-server/README.md`](mcp-server/README.md). The server is a thin, read-only client: it holds no credentials, bundles no corpus, and only calls FoJin's public endpoints — its default target is https://fojin.app/api, overridable via FOJIN_API_BASE_URL to point at a self-hosted instance.
