## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

No check matched anything in these tool definitions.


## Changes things (3)

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

### `screen_book`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Screens a surety broker's book of up to 25 Railroad Commission of Texas operator numbers (principals) with the surety-book-v1 semantics: one row per principal in request order with the P-5 letter verbatim (A labelled active, D delinquent, any other letter unlabelled), claims on file, AFFECTED on the evaluation date, approaching within 24 months, the Commission-published cost proxy with the priced claim count and the rate label read from the publication's cost_rate_basis (a fiscal year's Commission rates, or the publication's own label verbatim when it establishes no table year), unpriced claims, the Full Wellbore flagged counts (a cross-check only) and the 16 TAC §3.78 blanket floor from inactive wells only (a lower bound, not a bond amount). Book totals are given only where a sum is valid; unpriced claims and the floors are NOT_SUMMED, with the reason. Wellbores two principals of the book both claim are disclosed with the claims and cost the totals count more than once. A principal not in the publication refuses the whole book rather than leave a row out.
```

### `screen_operators`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Screens up to 200 Railroad Commission of Texas operator numbers at once and returns one row per requested operator, in request order: inactive wellbores on the IWAR, affected, approaching by 2042-09-01 (compliance-plan horizon), contested, review and shared claims, Commission-published plugging cost on affected wellbores with its rate label, unpriced affected count, on editions that carry the Full Wellbore cross-check the affected claims whose wellbore that file flags as plugged (a cross-check only; it changes no outcome, count or cost), the crossing schedule by bucket (empty buckets left out of the rows), the raw P-5 status code, and a 16 TAC §3.78 blanket-assurance floor computed from inactive wells only (a lower bound, not a bond amount). Operators not in the publication come back as found:false rows. Includes totals over the found rows.
```

### `verify_publication`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Recomputes the publication root hash from the manifest copy bundled with this server, reports the SHA-256 and byte count of each manifest data file as verified against the manifest when the server was built (all files, or the given paths), and re-hashes every bundled derived index file against its build attestation. Also returns the manifest URL and file URL template for an independent check, and the manifest's Full Wellbore cross-check counts when the edition carries them.
```

## Only reads (6)

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

### `get_operator_exposure`

- The name "get_operator_exposure" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "return" and "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Returns one operator's SB 1150 screening exposure from the publication, by six-digit Railroad Commission of Texas operator number: wellbore claim counts (affected, approaching by 2042-09-01 (compliance-plan horizon), review, contested, shared), the Commission-published plugging cost summed over affected wellbores with its rate label, the crossing schedule by year as published and, on editions that carry the Full Wellbore cross-check, the affected claims whose wellbore that file flags as plugged (a cross-check only; it changes no outcome, count or cost).
```

### `get_plug_record`

- The name "get_plug_record" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Returns the publication's plug record (contract 1.4.0 and later): W-3 plug dates on the Railroad Commission of Texas Full Wellbore file, counted by the calendar year the operator reported and by district, as published. Without a district it returns the statewide count for each year and each district's count for each year. With a district it returns that district's years with state-funded plug numbers, well types and district bases. With rows_limit it pages the per-wellbore rows one district and one year's count is made of, each with the line of the Full Wellbore file it was read from. Every response carries the publication's claims with their labels (DOCUMENTED_FACT, INFERENCE, UNKNOWN), the two UNKNOWN claims that travel with every count, and the publication's statement of what the record is not. This server computes no figure from these counts and combines none with the screening counts. On an edition without a plug record the plug_record field is null.
```

### `get_publication`

- The name "get_publication" says "get": a word for reading.
- Tag private-data: The description's first sentence says "describe" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Describes the WellState SB 1150 screening publication served here: root hash, publication id, contract (schema) version, evaluation date, the Railroad Commission of Texas source file with its SHA-256, the screening rule parameters and headline counts, the Commission rate table the plugging costs were computed from, the manifest's Full Wellbore cross-check counts and, from contract 1.4.0, the plug record's basis with its claims and their labels (DOCUMENTED_FACT, INFERENCE, UNKNOWN), each when the edition carries it. The verified field is true when the bundled copy of the manifest recomputes to the pinned root hash and the derived-data attestation matches the digest pinned at build time.
```

### `get_well`

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

Description, as the server wrote it:

```untrusted-server-text
Returns one wellbore's screening record by its 8-digit API number as the Commission's Inactive Well Aging Report records it (county code + unique number, no 42 state prefix): lease, well number, district, county, months inactive, oldest well record date (RRC), screening outcome, date affected, per-operator evaluations, Commission-published plugging cost with the per-foot rate it was computed from (fiscal year, district, USD per foot) when the edition publishes it, the Full Wellbore plug flag and latest W-3 plug date as a cross-check when the edition carries it (it changes no outcome, count or cost), and source line references.
```

### `list_operator_wells`

- The name "list_operator_wells" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists one operator's wellbore claims from the publication, filtered by outcome (AFFECTED, APPROACHING or ALL; default AFFECTED) and sorted by Commission-published plugging cost descending, unpriced wellbores last, then by API number. Returns one page of at most 100 rows plus the number matching and the Commission-published cost total over all matching rows (the same on every page). When more rows remain, next_cursor is set: pass it back as cursor, with the same operator_number and outcome, for the next page. A cursor is bound to the publication root that issued it.
```

### `search_operators`

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

Description, as the server wrote it:

```untrusted-server-text
Finds operators whose Railroad Commission of Texas name contains the given text, case-insensitive. Returns up to 20 matches with operator number, display name, wellbore claims and affected count, ordered by affected count descending, then by name.
```
