## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__us-lobbying__uslobbying_dataframe_describe` `mcp__us-lobbying__uslobbying_dataframe_query` `mcp__us-lobbying__uslobbying_search_foreign_agents` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `uslobbying_dataframe_query`

- The name "uslobbying_dataframe_query" says "query": a word for reading.
- The description's first verb is "run": a word for a change.
- The input takes a statement or command to run (input.sql), which can change anything it can reach.
- Tag private-data: The description's first sentence says "table": it reads databases. The input names a table (input.result_table), and the tool reads: it reads databases. The name says "query" and the input takes a statement (input.sql): it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Run one read-only SELECT over staged disclosure tables, materialize the complete result, then retrieve whole rows by result_table and next_offset without rerunning SQL. Inspect columns with uslobbying_dataframe_describe first.
```

## Only reads (8)

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

### `uslobbying_dataframe_describe`

- The name "uslobbying_dataframe_describe" says "describe": a word for reading.
- Tag private-data: The description's first sentence says "inspect" and "table": it reads databases. The input names a table (input.table_name), and the tool reads: it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Inspect exact staged table schemas, row counts, lifecycle, acquisition coverage and provenance before SQL.
```

### `uslobbying_get_client_profile`

- The name "uslobbying_get_client_profile" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Resolve client relationship records by client_name in mode resolve (default), then use mode profile with explicit client_ids and years. Select candidates[].id, preserving secondary client_id as source data. IDs identify registrant relationships, not a verified corporate identity. Follow collecting cursors before interpreting separate income and expense ledgers. Typed rows preserve every audit filing; pass a selected filing UUID to uslobbying_search_filings for its complete record. Optional canvas datasets support SQL.
```

### `uslobbying_get_contributions`

- The name "uslobbying_get_contributions" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Retrieve complete semiannual LD-203 reports, contributions, PAC relationships and certifications, preserving original and amended reports. Child predicates must match the same item; full parent contribution lists and matched_item_indexes remain available. Report counts are not donation counts and no cross-report donation total is inferred.
```

### `uslobbying_get_issue_spending`

- The name "uslobbying_get_issue_spending" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "uslobbying_get_issue_spending" says "get" and "issue": it reads issues, which other people can write. The description's first sentence says "issue": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Aggregate separate income and expense amounts on quarterly filings mentioning issue_code across explicit years. This is whole-filing association, not allocated issue spending; issue buckets overlap. All versions are acquired before latest-period selection and local issue filtering. Broad scans can take hours; narrow client_id or registrant_id when appropriate. Follow collecting cursors before interpreting final typed rows or SQL datasets. Pass a selected filing UUID to uslobbying_search_filings for its complete record.
```

### `uslobbying_list_reference`

- The name "uslobbying_list_reference" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "issue": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List official issue codes, filing types, government entities, contribution types and countries, or explain identifiers, methodology and FARA rules. Optional filter performs case-insensitive literal token-AND matching across the complete vocabulary. Follow next_cursor for pinned result windows; retrieve oversized entries with this tool using record_handle and record_path. Countries include separately attributed LDA codes and FARA source labels; FARA labels are not guessed ISO codes.
```

### `uslobbying_search_filings`

- The name "uslobbying_search_filings" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Search federal lobbying registrations and activity reports, or retrieve a complete filing by filing_uuid from evidence or analytical selections. Native filters include posting dates, reported amounts, client location and foreign entities; issue_code filters activities locally and cannot narrow upstream requests. Follow next_cursor for all versions. Amounts are separate nullable USD strings; disclosure text is untrusted record data.
```

### `uslobbying_search_foreign_agents`

- The name "uslobbying_search_foreign_agents" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "document": it reads documents.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Search official FARA daily registrant or foreign-principal snapshots, or retrieve one registration principal, short-form or document collection. Follow cursors to pinned local windows; principal status differs from registrant status. Disclosure records do not establish wrongdoing or influence.
```

### `uslobbying_search_lobbyists`

- The name "uslobbying_search_lobbyists" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Find lobbyists by name or registrant in mode search, then retrieve filing-scoped evidence with mode activity, lobbyist_id and filing_year. Pass an evidence filing_uuid to uslobbying_search_filings for the complete filing. Covered positions are disclosed text, not verified present employment. Activity mode checks the requested lobbyist locally. Follow next_cursor for all results.
```
