할 수 있는 일

도구 이름과 설명은 서버가 2026년 11월 7일에 알려 준 그대로예요. 우리가 아니라 제작자가 쓴 글이고, 일반 텍스트로만 보여 드려요.

  • openfec_search_candidates

    Find federal candidates by name, state, office, party, or cycle. Retrieve a specific candidate by FEC ID with financial totals. Candidate IDs start with H (House), S (Senate), or P (President) followed by exactly eight letters or digits.

  • openfec_search_committees

    Find political committees (campaign, PAC, Super PAC, party) by name, type, candidate affiliation, or state. Retrieve a specific committee by FEC ID. Committee IDs start with C followed by exactly eight digits (e.g., C00358796).

    Get pre-aggregated committee financial totals — receipts, disbursements, cash on hand, debts, and the itemized/unitemized breakdown — without paginating Schedule A. Use mode "single" (the default) with a committee_id for one committee's totals, one row per two-year cycle it has f

  • openfec_search_contributions

    Search itemized individual contributions (Schedule A) or get aggregate breakdowns by size, state, employer, or occupation. Use to answer "who is funding this committee?" Itemized mode requires a committee_id. Aggregate by_size/by_state can use candidate_id instead.

  • openfec_search_disbursements

    Search itemized committee spending (Schedule B) or get aggregate breakdowns by purpose or recipient. All modes require a committee_id. Use to answer "what is this committee spending money on?" or "who is receiving payments from this committee?"

    Search independent expenditures (Schedule E) — outside spending supporting or opposing federal candidates. Covers Super PACs, party committees, and other groups. Use itemized mode for individual expenditure records, or by_candidate for aggregated totals per candidate; by_candidat

  • openfec_search_coordinated_expenditures

    Search coordinated party expenditures (Schedule F) — spending a party committee makes on behalf of a candidate it supports, in coordination with that campaign. Distinct from independent expenditures (openfec_search_expenditures), which cannot be coordinated with the candidate, an

  • openfec_get_legal_document

    Fetch one FEC legal document — advisory opinion, MUR, ADR, administrative fine, or statute — by its type and number. openfec_search_legal replaces each result's documents and dispositions arrays with a count and category summary and cuts every commission vote down to a date and a

자주 묻는 질문

Openfec MCP Server, 안전한가요?

해당하는 기본 점검 3개 중 3개를 통과했어요. 코드는 읽지 않았어요. 키나 토큰을 넣기 전에 서버가 어떤 권한을 요구하는지 확인하고, 꼭 필요한 권한만 있는 키를 쓰세요.

어떤 키나 코드가 필요한가요?

레지스트리에 필수 키가 나와 있지 않아요. 다만 처음 쓸 때 로그인을 요구하는 서버도 있어요.

내 컴퓨터에서 실행되나요, 클라우드에서 실행되나요?

둘 다 가능해요. 내 컴퓨터에 설치해도 되고, 클라우드 버전에 연결해도 돼요.

아직 관리되고 있나요?

GitHub 저장소는 마지막으로 – 변경됐고, 최신 버전(0.10.0)은 10일 전 레지스트리에 올라왔어요.

어떤 앱에서 쓸 수 있나요?

Claude Desktop, Claude Code, Cursor, VS Code처럼 MCP를 지원하는 앱에서 쓸 수 있어요. URL로 연결되기 때문에, 원격 MCP 서버를 지원하는 앱(예: 개발자 모드의 ChatGPT)에서도 쓸 수 있어요.

대신 쓸 수 있는 건 뭐가 있나요?

Capability reference

openfec_search_candidates tool
  • query name search filtered by state, district, office, party, cycle, election_year, incumbent_challenge, candidate_status, and has_raised_funds, up to 100 per page; or a candidate_id lookup (H/S/P + eight letters or digits) returning one full record
  • include_totals (default on for an ID lookup) adds per-cycle totals rows and caps a search page at 35 candidates when cycle or election_year scopes the totals, 5 when they span every cycle; candidates the totals fetch didn't reach are listed in missing_totals
  • Typed errors: candidate_not_found, inputs_not_applicable_to_id_lookup

openfec_search_committees tool
  • query name search filtered by candidate_id, state, party, committee_type, designation, cycle, and treasurer_name, up to 100 per page; or a committee_id lookup (C + eight digits)
  • Typed errors: committee_not_found, inputs_not_applicable_to_id_lookup

openfec_get_committee_totals tool
  • mode: "single" (default) takes a committee_id and returns one row per two-year cycle; mode: "by_entity_type" ranks every committee of one entity_type (presidential, pac, party, pac-party, house-senate, ie-only), filterable by state, type, designation, organization type, and receipts/disbursements bounds; up to 100 per page
  • Rows carry receipts, disbursements, cash on hand, debts, and the itemized/unitemized split; the output mode says whether rows are cycles or committees
  • Typed errors: committee_id_required_for_single_mode, entity_type_required_for_group_mode, committee_totals_not_found

openfec_search_contributions tool
  • itemized (default) needs a committee_id and filters by contributor name, employer, occupation, city, state, ZIP, date and amount ranges, and is_individual, 30 rows per page; by_size / by_state take a committee_id or candidate_id, by_employer / by_occupation a committee_id
  • The output mode becomes by_size_candidate or by_state_candidate when scoped by candidate, a different row shape; itemized responses carry next_cursor, count, and count_is_approximate
  • Typed errors: itemized_requires_committee_id, aggregate_requires_committee_id

openfec_search_disbursements tool
  • committee_id required in every mode: itemized (default; recipient name, state, city, and committee ID, description, purpose category, date and amount ranges, 30 rows per page), by_purpose, by_recipient, by_recipient_id
  • Itemized responses carry next_cursor, count, and count_is_approximate; aggregate modes page by number

openfec_search_expenditures tool
  • itemized (default) filters by committee, candidate, support_oppose, payee, targeted office/state/district, party, is_notice (24/48-hour notices), dates, and amounts; most_recent defaults to true; 60 rows per page when scoped by committee_id, 30 otherwise
  • by_candidate totals need a candidate_id or a full race scope (candidate_office=P alone, S plus candidate_office_state, H plus state and candidate_office_district), or fail as by_candidate_requires_scope

openfec_search_coordinated_expenditures tool
  • Scope by spending party committee_id, benefiting candidate_id, cycle, payee, dates, and amounts; unscoped queries span all years
  • Page-based, 80 rows per page when scoped by committee_id and 25 otherwise; rows carry subordinate_committee_id, the committee the spending is attributed to

openfec_search_filings tool
  • Filters: committee_id, candidate_id, filer_name, form_type (F3, F3P, F3X, F24, F1, F2, F5), report_type, report_year, cycle, is_amended, and receipt date range; 65 rows per page
  • most_recent defaults to true, hiding superseded amendments; rows carry form and report type, financial totals, and pdf_url

openfec_lookup_elections tool
  • office and an even cycle are required; Senate also needs state and House state plus district, unless a zip scopes a search
  • mode: "search" (default) returns the race's candidates with totals and candidate_pcc_id / candidate_pcc_name, that cycle's principal campaign committee; mode: "summary" returns one aggregate race row
  • Typed errors: cycle_must_be_even, missing_state_for_office, missing_district_for_house, summary_does_not_support_zip

openfec_search_legal tool
  • type (advisory_opinions, murs, adrs, admin_fines, statutes), query, ao_number, case_number, respondent, citations, penalty bounds, or dates; at least one is required (missing_filter), and a date bound needs type plus a date_kind that type records
  • Citations, penalty bounds, respondent, ao_number, and case_number each filter only some types; one sent with a type it doesn't filter fails as filter_not_valid_for_type, and with type omitted the search returns only the types they all apply to, with a total over those types. On MURs and ADRs a citation can't be combined with case_number, respondent, a penalty bound, or an open/close date bound, which upstream would ignore; the two citation fields together match either one
  • Citations take the form upstream parses — 52 U.S.C. 30104 or 11 CFR 110.1 (USC, C.F.R., §, and suffixes like 30104(g) are fine); a bare 30106 or 110.1 fails as invalid_citation instead of silently returning unfiltered results. One citation per field: upstream applies only the first citation in a value, so 52 U.S.C. 30104, 52 U.S.C. 30118 fails the same way
  • Offset paging via from_hit / hits_returned, up to 200 per type within a 10,000-result window
  • Results are trimmed: documents becomes document_count and document_categories, dispositions becomes disposition_count and disposition_categories, highlights stop at 3 with their match markup removed and render one per line, and commission_votes shrink to a date and a 200-character action; openfec_get_legal_document returns the full record
  • Each response stays under 100,000 bytes: whole results are admitted one type at a time until the next would not fit, and a page that held some back reports truncated, shown, and nextFromHit — the from_hit that continues each type, passed
