Anlyon alternative
1 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

uslobbying_dataframe_queryRun 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.Reads private dataNo findings
Why it is in this group
- 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.
What it can reach
- private-dataThe description's first sentence says "table": it reads databases.
- private-dataThe input names a table (input.result_table), and the tool reads: it reads databases.
- private-dataThe name says "query" and the input takes a statement (input.sql): it reads databases.
Description, as the server wrote it 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.

uslobbying_get_client_profileResolve client relationship records by client_name in mode resolve (default), then use mode profile with explicit client_ids and years.Reads text others writeNo findings
Why it is in this group
- The name "uslobbying_get_client_profile" says "get": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it 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_contributionsRetrieve complete semiannual LD-203 reports, contributions, PAC relationships and certifications, preserving original and amended reports.Reads text others writeNo findings
Why it is in this group
- The name "uslobbying_get_contributions" says "get": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it 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_spendingAggregate separate income and expense amounts on quarterly filings mentioning issue_code across explicit years.Reads text others writeNo findings
Why it is in this group
- The name "uslobbying_get_issue_spending" says "get": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- untrusted-inputThe name "uslobbying_get_issue_spending" says "get" and "issue": it reads issues, which other people can write.
- untrusted-inputThe description's first sentence says "issue": it reads issues, which other people can write.
Description, as the server wrote it 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.
Annotations the server declares
- readOnlyHint: true

- openWorldHint: true
uslobbying_list_referenceList official issue codes, filing types, government entities, contribution types and countries, or explain identifiers, methodology and FARA rules.Reads text others writeNo findings
Why it is in this group
- The name "uslobbying_list_reference" says "list": a word for reading.
What it can reach
- untrusted-inputThe description's first sentence says "list" and "issue": it reads issues, which other people can write.
Description, as the server wrote it 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_filingsSearch federal lobbying registrations and activity reports, or retrieve a complete filing by filing_uuid from evidence or analytical selections.Reads text others writeNo findings
Why it is in this group
- The name "uslobbying_search_filings" says "search": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it 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.

Why it is in this group
- The name "uslobbying_search_foreign_agents" says "search": a word for reading.
What it can reach
- private-dataThe description's first sentence says "search" and "document": it reads documents.
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it 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.

- The name "uslobbying_search_lobbyists" says "search": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it 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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.
- Reads private data3
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write7
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
