US federal campaign finance data from the FEC's OpenFEC API. Search candidates, committees, and filings, trace contributions (Schedule A), disbursements (Schedule B), and independent and coordinated party expenditures (Schedules E/F), and look up election races, legal documents, and filing deadlines. Runs as a stdio process, a local Streamable HTTP server, or the public hosted endpoint above.

## Capability reference

### `openfec_search_candidates` <sub>tool</sub>

- Full-text name search, or a direct lookup by FEC candidate ID (H/S/P + eight letters or digits) that returns full detail
- Filters: state, district, office, party, cycle, election_year, incumbent_challenge, candidate_status, has_raised_funds
- `include_totals` merges receipts/disbursements/cash-on-hand per cycle — defaults to true on an ID lookup, false on search; capped at 5 pages of 100 rows, with uncovered IDs listed in `missing_totals` for re-query
- Pagination up to 100 results per page
- Typed errors: `candidate_not_found`; `inputs_not_applicable_to_id_lookup` when search-only filters accompany a direct ID lookup

---

### `openfec_search_committees` <sub>tool</sub>

- Full-text name search, or a direct lookup by FEC committee ID (`C` + eight digits)
- Filters: candidate_id, state, party, committee_type, designation, cycle, treasurer_name
- Pagination up to 100 results per page
- Typed errors: `committee_not_found`; `inputs_not_applicable_to_id_lookup` when search-only filters accompany a direct ID lookup

---

### `openfec_get_committee_totals` <sub>tool</sub>

- `mode: "single"` (default): one committee's totals, one row per two-year cycle filed. `mode: "by_entity_type"`: ranks or screens every committee of one entity type (presidential, pac, party, pac-party, house-senate, ie-only)
- `by_entity_type`-only filters: committee_state, committee_type, committee_designation, organization_type, and receipts/disbursements min/max bounds
- Returns receipts, disbursements, cash on hand, debts, and the itemized/unitemized contribution split
- Typed errors: `committee_id_required_for_single_mode`, `entity_type_required_for_group_mode`, `inputs_not_applicable_to_mode`, `committee_totals_not_found`

---

### `openfec_search_contributions` <sub>tool</sub>

- Modes: `itemized` (Schedule A records, requires committee_id, keyset cursor pagination), `by_size`/`by_state` (committee_id or candidate_id), `by_employer`/`by_occupation` (committee_id only)
- Itemized filters: contributor name, employer, occupation, city, state, ZIP, date range, amount range, is_individual; defaults to the current cycle when omitted
- Sort defaults to `-contribution_receipt_date`; a cursor is valid only for an otherwise-identical call
- Typed errors: `itemized_requires_committee_id`, `aggregate_requires_committee_id`, `itemized_only_filters_in_aggregate_mode`, `inputs_not_applicable_to_mode`

---

### `openfec_search_disbursements` <sub>tool</sub>

- Modes: `itemized` (Schedule B records, keyset cursor pagination), `by_purpose`, `by_recipient`, `by_recipient_id` — committee_id required for every mode
- Itemized filters: recipient name/state/city/committee ID, description, purpose category, date range, amount range; defaults to the current cycle when omitted
- Sort defaults to `-disbursement_date`
- Typed errors: `itemized_only_filters_in_aggregate_mode`; `inputs_not_applicable_to_mode` for an explicit page in itemized mode

---

### `openfec_search_expenditures` <sub>tool</sub>

- Modes: `itemized` (Schedule E, keyset cursor pagination, defaults to the current cycle and `most_recent: true`) and `by_candidate` (aggregated per targeted candidate — needs candidate_id or a full race scope: office alone for President, plus state for Senate, plus district for House)
- Itemized filters: payee_name, candidate_party, is_notice (24/48-hour notices), date range, amount range, support_oppose (S/O)
- Typed errors: `by_candidate_requires_scope`, `itemized_only_filters_in_aggregate_mode`, `inputs_not_applicable_to_mode`

---

### `openfec_search_coordinated_expenditures` <sub>tool</sub>

- Schedule F — party committee spending coordinated with a candidate's campaign, a separate legal category from independent expenditures and direct contributions
- Filters: committee_id (spending party committee), candidate_id (benefiting candidate), cycle, payee_name, date range, amount range; unscoped queries span all years
- Page-based pagination; the spending committee is hoisted out of rows when committee_id is supplied

---

### `openfec_search_filings` <sub>tool</sub>

- Form types: F3 (House/Senate quarterly), F3P (Presidential), F3X (PAC/party), F24 (24-hour IE notice), F1 (statement of organization), F2 (statement of candidacy), F5 (IE by persons)
- Filters: committee_id, candidate_id, filer_name, report_type, report_year, cycle, is_amended, receipt date range
- `most_recent` defaults to true, filtering out superseded amendments
- Page-based pagination, up to 100 results per page
