## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `commentaries`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
What 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 no other tool
    exposes for the Chinese canon: CBETA marks up almost none of it, and the
    alignment behind this was derived text by text.

    Two things to read carefully rather than skim. `total` is how many
    commentators the passage actually has — `truncated` says the list you got
    is a sample. And coverage is partial: roughly half of what a commentator
    wrote is not aligned, so an absent commentator means "not in the data",
    never "he said nothing". When nothing matches, `available_sutras` tells
    you which sūtras have data at all — do not read a miss as silence from the
    tradition.
    
```

### `verify_quote`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Verify 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 near-miss window when it wasn't. `cite` optionally narrows the
    search — a CBETA id ("T0374") or fojin URN ("fojin:cbeta/T0374.13") —
    and `cite_matched` reports honestly whether the quote is where you
    claimed (a hit in a different fascicle does NOT confirm your citation).
    Quote must be ≥4 CJK chars after normalisation; Classical Chinese only.
    Short quotes are answered but say less: a four-character phrase recurs
    across the canon, so read `cite_matched` rather than `verbatim`, and check
    `matches_capped` before treating the list as complete. Each match carries
    an absolute `reader_url` — cite that, not a reconstructed third-party link.
    
```

## Only reads (6)

Looks things up and changes nothing. Claude Code: allow.

### `get_parallels`

- The name "get_parallels" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Cross-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 hundreds. To
    narrow them to one passage, match the passage against `source_chunks[].text`
    and keep the parallels whose `aligns_source_chunk` equals that chunk_index.

    `urn` is filled for parallels that are fojin works; rows with
    `source="mitra-parallel"` are inline Skt/Tib sentences with no fojin work to
    cite, so they carry `original_preview` instead and stay `urn: null`.
    
```

### `lookup_dictionary`

- The name "lookup_dictionary" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a Buddhist term across fojin's dictionaries (748K+ entries).
```

### `lookup_entity`

- The name "lookup_entity" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search fojin's knowledge graph for entities — people, places, works,
    doctrinal terms — matching `query`.
```

### `read_passage`

- The name "read_passage" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read 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.
    
```

### `resolve_urn`

- The name "resolve_urn" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve 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.
```

### `search_corpus`

- The name "search_corpus" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Semantic 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).
    
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `fojin`:

```json
{
  "permissions": {
    "allow": [
      "mcp__fojin__search_corpus",
      "mcp__fojin__read_passage",
      "mcp__fojin__get_parallels",
      "mcp__fojin__lookup_dictionary",
      "mcp__fojin__lookup_entity",
      "mcp__fojin__resolve_urn"
    ],
    "ask": [
      "mcp__fojin__verify_quote",
      "mcp__fojin__commentaries"
    ],
    "deny": []
  }
}
```
