usaspending-mcp-server

List all top-tier federal agencies with toptier codes, agency slugs, budget authority amounts, and obligation totals for the current fiscal year. Use this as the entry point for agency navigation — toptier codes and agency slugs are required inputs for usaspending_get_agency and agency-based filters on spending analysis tools.

Look up valid code values for filter fields by searching free-text descriptions. Use the type parameter to select the lookup table: naics (NAICS industry codes), psc (product/service codes), cfda (CFDA/Assistance Listing program numbers), awarding_agency (agency and sub-agency names, each with its tier and top-tier parent — the agency_name filters take the top-tier name), or recipient (recipient names with UEI/DUNS). Call this before filtering awards when you know a description but not the exact code. Returns matching codes and names for use in other tool filters.

Search federal awards by keyword, recipient, agency, award type, NAICS code, assistance listing (CFDA) number, PSC, DEF code, location, or date range. Returns ranked award summaries including recipient names, amounts, awarding agencies, and generated award IDs for use with usaspending_get_award; loan rows carry loan value, subsidy cost, and issue date in place of award amount and dates. Award types: A/B/C/D = contracts, IDV_A–IDV_E = IDVs, 02/03/04/05/F001/F002 = grants, 06/10/F006/F007 = direct payments, 07/08/F003/F004 = loans, 09/11/-1/F005/F008/F009/F010 = other assistance. Dates must be ISO 8601 (YYYY-MM-DD). Earliest data: 2007-10-01 via search API. DoD contracts have a 90-day publication lag.

Fetch full details of a federal award by its generated unique award ID. Returns contract or assistance award data including recipient identity (UEI, parent organization, business categories), agency hierarchy, period of performance, place of performance, Assistance Listings with the obligation under each, loan face value and subsidy cost for loans, funding account linkages (account_obligations_by_defc), parent IDV information, and subaward count. Use generated_internal_id values from usaspending_search_awards as input. Recipient and parent recipient hashes can be passed to usaspending_get_recipient; NAICS codes can be used in usaspending_search_awards filters, and Assistance Listing numbers in its assistance_listings filter. For IDV-category awards (category="idv"), use usaspending_get_idv_awards to list the child contracts and task/delivery orders placed under them.

List individual transactions (contract modifications, grant amendments) on a federal award. Each transaction represents a change event — obligation modifications, performance period extensions, scope changes, etc. Use this to trace the spending history and obligation changes over the life of an award. Award IDs come from usaspending_search_awards (generated_internal_id field).

List subaward contracts or grants under a prime federal award. Reveals the sub-contractor or sub-grantee layer — the organizations that actually perform the work. Each row shows the subaward number, amount, description, action date, and recipient. Check subaward_count on usaspending_get_award first to confirm subawards exist before calling this tool.

List the Treasury federal accounts that funded an award, with the amount obligated from each and the funding agency behind it. This is the award → appropriation link: each row returns federal_account (AGENCY-MAIN format, e.g. 080-0120) to chain into usaspending_get_federal_account for the account budget detail. The award_id must be a generated_unique_award_id — from usaspending_search_awards (generated_internal_id field) or usaspending_get_award. Distinct from usaspending_get_award account_obligations_by_defc, which breaks funding down by Disaster/Emergency Funding code rather than by account. An award_id that does not exist returns an empty list rather than an error.

List child contracts and task/delivery orders placed under an IDV (Indefinite Delivery Vehicle) award. Each row includes the generated_unique_award_id to chain into usaspending_get_award for full detail. The award_id must be the generated_unique_award_id of the parent IDV — obtainable from usaspending_search_awards (generated_internal_id field) or from usaspending_get_award. IDV category awards returned by usaspending_get_award have child orders accessible via this tool.

Search for organizations or individuals receiving federal funds by name, UEI (Unique Entity Identifier), or DUNS. Returns recipient hash IDs, UEI/DUNS identifiers, total award amounts, and hierarchy level. Results are paginated — use page to retrieve matches beyond the first page; page_metadata.total reports the full match count. Recipient hash IDs from this tool can be passed to usaspending_get_recipient for full profiles. Recipient level: P = parent organization, C = child entity, R = standalone.

Fetch a recipient's full profile including address, business type codes, parent organization, alternate names, and total transaction and loan amounts. Recipient IDs are UUID hashes with a level suffix (-P parent, -C child, -R standalone) from usaspending_search_recipients or usaspending_get_award. Totals cover the trailing 12 months unless fiscal_year selects one fiscal year, and period names the window. For a recipient's totals by award type, use usaspending_spending_over_time with filters.recipient_id and award_type_codes. UEI and DUNS values can be used to cross-reference with SAM.gov and SEC EDGAR.

Fetch an agency's fiscal-year overview including mission, budgetary resources, obligation and outlay totals (for the most recent fiscal year with reported budget data), sub-agency count, and DEF codes for disaster/emergency funding. Also returns a paginated sub-agency breakdown with obligation and transaction counts for the same fiscal year as the budget totals (the current fiscal year when no budget year is available within 5 seconds); sub_agency_fiscal_year names the year it covers. Accepts exactly one of a 3-digit toptier_code (e.g., 097 for DoD, 012 for Agriculture) or an agency_slug (e.g., department-of-defense) — both appear in usaspending_list_agencies results and award search results. When the budget or sub-agency request fails, the overview is still returned and unavailable_sections names each missing section with its reason.

Aggregate federal spending by state, county, or congressional district. Useful for per-capita analysis, regional comparisons, and mapping federal investment patterns. Filter by keyword, award type, agency, recipient, NAICS code, Assistance Listing, PSC, DEF code, or date range. Areas are ranked by obligation and capped at limit; to retrieve specific areas, including ones ranked past the cap, list their codes in shape_codes — a 2-letter postal code for state, a 5-digit state + county FIPS code for county, or a 4-digit state FIPS + district number for district — NOT place names. Resolve place names to these codes using a geocoding server (Census or OpenStreetMap) first. Chain per-capita results with Census population data for meaningful comparisons.

Aggregate federal spending grouped by a specific dimension: NAICS industry code, PSC product/service code, awarding agency, funding agency, CFDA assistance program, or recipient. Returns top items with obligation amounts — useful for trend and breakdown analysis. Filter by keyword, award type, agency, recipient, NAICS code, Assistance Listing, PSC, DEF code, or date range. Chain NAICS, PSC, and CFDA codes back into these filters, into usaspending_search_awards filters, or into usaspending_autocomplete_filters lookups. recipient_duns rows carry recipient_id, which opens the recipient profile in usaspending_get_recipient, and uei.

Fetch aggregated federal obligation amounts grouped by fiscal year, fiscal quarter, or fiscal month. All grouping is relative to the US government fiscal year (Oct–Sep), so fiscal month 1 is October, not January. Filter by award type, agency, recipient, keyword, NAICS code, Assistance Listing, PSC, or DEF code to trace spending trends in a specific area; award types default to contracts. Returns per-period totals and optional breakdowns by award category (contracts, grants, direct payments, IDVs, loans, other).

Fetch disaster and emergency supplemental spending (COVID-19, hurricanes, infrastructure law, etc.) broken down by agency, CFDA assistance program, recipient, or geography. Use the dimension parameter to select the breakdown axis: overview (top-level totals), agency, cfda, recipient, or geography. Filter by DEF codes (Disaster/Emergency Funding codes) to isolate a specific emergency appropriation. DEF codes appear in usaspending_get_award account_obligations_by_defc and usaspending_get_agency def_codes fields.

Fetch a federal account's budget data: total obligations, gross outlays, and budgetary resources, plus the per-Treasury-Account-Symbol (TAS) component breakdown in children. Federal accounts connect appropriations law to actual agency spending. Account codes come from usaspending_search_federal_accounts (its account_number output field) or usaspending_get_award_federal_accounts (its federal_account field), and are formatted as AGENCY-MAIN (e.g., 097-0100 for DoD Operation and Maintenance). For obligations broken down by program activity or object class, use usaspending_get_federal_account_breakdown.

Fetch a federal account's obligations broken down by program activity (what the money funds) or object class (what it buys — personnel, supplies, contracts). Use the dimension parameter to select the axis. Account codes are AGENCY-MAIN format and come from usaspending_search_federal_accounts (its account_number output field), usaspending_get_award_federal_accounts (its federal_account field), or usaspending_get_federal_account. Paginated with an honest total count. For the account's own metadata and top-level totals, use usaspending_get_federal_account.

List and keyword-search federal accounts by agency identifier or title keyword. Returns account numbers, names, managing agencies, and budgetary resources. Use account_number from results as input to usaspending_get_federal_account for full budget detail. Use usaspending_list_agencies to look up agency_identifier codes (3-digit strings, e.g. "097" for DoD).
