## Overview
Federal award, recipient, agency, and spending data from USAspending.gov, the US Treasury's DATA Act transparency platform. Search and trace awards down to transactions, subawards, and funding accounts; profile recipients and agencies; and aggregate spending by geography, category, time, and disaster appropriation. Runs as a stdio process, a local Streamable HTTP server, or the public hosted endpoint above.

## Capability reference
### `usaspending_list_agencies` <sub>tool</sub>
- Takes only `sort` (`agency_name`, `budget_authority_amount`, `obligated_amount`, `outlay_amount`) and `order`; returns every agency in one unpaginated response
- Rows carry `toptier_code` and `agency_slug`, both accepted by `usaspending_get_agency`, plus current-year `budget_authority_amount`, `obligated_amount`, and `outlay_amount`
---
### `usaspending_autocomplete_filters` <sub>tool</sub>
- `type` (`naics`, `psc`, `cfda`, `awarding_agency`, `recipient`) plus `search_text`; `limit` 1–500, default 10
- Rows carry `code` and `name`, and `uei` / `duns` for recipients; no match fails as `no_match`. A `cfda` code goes in `assistance_listings` and a `psc` code in `psc_codes` on `usaspending_search_awards` and the three spending analytics tools
- Agency rows carry the matched agency's own `name`, `abbreviation`, and `tier` (`toptier` or `subtier`), plus its parent's `toptier_name` and `toptier_code`. The `agency_name` filters are top-tier only and take `toptier_name`, so a sub-agency such as the U.S. Geological Survey filters at its whole department
- `naics` matches official NAICS title text: "software" resolves, "cybersecurity" does not, so search with the industry term a title would use
---
### `usaspending_search_awards` <sub>tool</sub>
- Filters: `keyword`, `agency_name`, `recipient_name`, `naics_codes`, `assistance_listings` (Assistance Listing numbers such as `93.866`, from `usaspending_autocomplete_filters` `type: cfda`), `psc_codes` (1–4 characters, where a prefix such as `Y1` covers the codes under it; contracts and IDVs only), `def_codes` (Disaster Emergency Fund Codes such as `Z`; PSC and DEF codes are sent uppercased), `time_period` (`YYYY-MM-DD` from 2007-10-01 on; either end may be given alone), and `location_filter` (`country` defaults to `USA`, and a territory code such as `PRI` becomes `USA` plus its state; `state` as a postal or 2-digit FIPS code, `FM`/`MH`/`PW`/`UM` and armed-forces `AA`/`AE`/`AP` included, or under another country as that country's own 2-letter subdivision code such as `ON` with `CAN`; `county` as 3 digits with `state` or the 5-digit FIPS code alone; echoed as `applied_location`); `award_type_codes` defaults to contracts (`A`–`D`) and must stay in one group: IDVs `IDV_A`–`IDV_E`, grants `02`–`05`/`F001`/`F002`, direct payments `06`/`10`/`F006`/`F007`, loans `07`/`08`/`F003`/`F004`, or other assistance `09`/`11`/`-1`/`F005`/`F008`/`F009`/`F010`; `limit` up to 100
- Rows carry `generated_internal_id` for `usaspending_get_award` and `agency_slug` for `usaspending_get_agency`; loan rows carry `loan_value`, `subsidy_cost`, and `issued_date` in place of amounts and dates. There is no total, and `page_metadata.has_next` is true on any full page. The nested `filters` object takes the analytics tools' `filters` keys, except `recipient_id`, and wins per field over the flat ones. Failures are `assistance_listings_type_mismatch` (listings with a non-assistance group), `psc_codes_type_mismatch` (PSC codes with an assistance group), `unsupported_sort`, `date_range_inverted`, `date_before_earliest`, and `invalid_location` (an unknown state, a 3-digit county without a state, a county under an armed-forces code (`AA`/`AE`/`AP`), a county or FIPS-number state under another country, or parts naming different states)
- `sort` depends on the group: loans take `Loan Value` (default), `Subsidy Cost`, `Issued Date`, `Recipient Name`, or `Awarding Agency`; the others `Award Amount` (default), `Total Outlays`, `Start Date`, `End Date` (not IDVs), `Recipient Name`, or `Awarding Agency`. Page numbers stop at a 50,000-result offset (`pagination_limit_exceeded`); past it, page with the `last_record_sort_value` + `last_record_unique_id` cursor, returned below a 10,000-result offset
---
### `usaspending_get_award` <sub>tool</sub>
- `award_id` is a `generated_unique_award_id`, the `generated_internal_id` from search; an unknown ID fails as `award_not_found`
- Returns `category`, `total_obligation`, `total_outlays`, `subaward_count`, NAICS / PSC codes, `account_obligations_by_defc`, and, on loans, `total_loan_value` and `total_subsidy_cost`
- `assistance_listings` lists every Assistance Listing on an assistance award, in upstream order, as `number`, `title`, and `obligation`; a `number` goes in `usaspending_search_awards` `assistance_listings`
- `recipient` carries `uei`, `parent_uei`, `business_categories` (category names, not the `business_types` codes of `usaspending_get_recipient`), and a three-letter `country_code` on its `location`, as does `place_of_performance`; a location with no fields upstream is omitted
- `recipient.recipient_id` and `recipient.parent_recipient_id` chain to `usaspending_get_recipient` and `parent_award.generated_unique_award_id` to the parent IDV; `category: "idv"` awards list their children via `usaspending_get_idv_awards`
---
### `usaspending_get_award_transactions` <sub>tool</sub>
- `award_id` plus `sort` (`action_date`, `federal_action_obligation`, `modification_number`); `limit` up to 100
- Rows carry `action_date`, `modification_number`, `action_type`, and a signed `federal_action_obligation` (negative is a deobligation)
---
### `usaspending_get_award_subawards` <sub>tool</sub>
- `award_id` plus `sort` (`subaward_number`, `description`, `action_date`, `amount`, `recipient_name`); `limit` up to 100
- Rows carry `subaward_number`, `amount`, `action_date`, `recipient_name`, `recipient_uei`, and place of performance; `subaward_count` on `usaspending_get_award` says whether any exist
---
### `usaspending_get_award_federal_accounts` <sub>tool</sub>
- `award_id` is a `generated_unique_award_id`; `limit` up to 100, with `page_metadata.count` as the total
- Rows carry `federal_account` (AGENCY-MAIN, e.g. `080-0120`) for `usaspending_get_federal_account`, `total_transaction_obligated_amount`, and the funding agency with its `funding_agency_slug`
---
### `usaspending_get_idv_awards` <sub>tool</sub>
- Parent IDV `award_id`; `type` is `child_awards` (task and delivery orders, the default), `child_idvs`, or `grandchild_awards`; `limit` up to 100
- Rows carry `generated_unique_award_id` for `usaspending_get_award`, `obligated_amount`, and performance dates; there is no total, and `has_next` is true on any full page
---
### `usaspending_search_recipients` <sub>tool</sub>
- `keyword` matches names, UEI, or DUNS, partial matches included; optional `award_type` scopes the totals; `limit` up to 100
- Rows carry `id` (a hash suffixed `-P` parent, `-C` child, or `-R` standalone) for `usaspending_get_recipient`, plus `uei`, `duns`, `recipient_level`, and `amount`; `page_metadata.total` is the full match count
---
### `usaspending_get_recipient` <sub>tool</sub>
- `recipient_id` from `usaspending_search_recipients` or `usaspending_get_award`; optional `fiscal_year` (2001–2030) scopes the totals to that fiscal year, which otherwise cover the trailing 12 months; an unknown ID fails as `recipient_not_found`
- Returns address, `business_types`, `parent_name` / `parent_uei`, `alternate_names`, `total_transaction_amount`, `total_transactions`, and loan face-value totals, with `period` naming the window (`FY2020` or `trailing 12 months`). Totals span every award type; for totals by type, use `usaspending_spending_over_time` with `filters.recipient_id` and `award_type_codes`
---
### `usaspending_get_agency` <sub>tool</sub>
- One of `toptier_code` (e.g. `097`) or `agency_slug` (e.g. `department-of-defense`); `page` walks the sub-agency list 10 at a time. Failures are `missing_input`, `conflicting_input` (both identifiers sent), and `agency_not_found`
- Returns `mission`, plus `budgetary_resources_amount`, `obligated_amount`, and `outlay_amount` for the most recent `fiscal_year` with reported budget data (a newly opened year with no amounts yet is skipped), `sub_agencies` with obligations and transaction and new-award counts for that same year (`sub_agency_fiscal_year` names it; without a budget year within 5 seconds the breakdown covers the current fiscal year), and `def_codes`
- A failed budget or sub-agency request still returns the overview: the missing fields are omitted and `unavailable_sections` names each section with its `reason` (`api_unavailable`, `api_timeout`, or `upstream_error`) and whether a retry may load it
---
### `usaspending_spending_by_geography` <sub>tool</sub>
- `scope` (`place_of_performance`, `recipient_location`) and `geo_layer` (`state`, `county`, `district`) are required; `filters` takes `keywords`, `award_type_codes`, `agency_name`, `recipient_id`, `naics_codes`, `assistance_listings`, `psc_codes`, `def_codes` (the same code filters as `usaspending_search_awards`, echoed as `applied_*`), and `time_period_start` / `time_period_end` (`YYYY-MM-DD`; either alone fills the other, as in `usaspending_search_awards`, `applied_time_period_*` echoes the range sent, a start after the end fails as `date_range_inverted`, and a range starting before 2007-10-01 fails as `date_before_earliest`); `limit` 1–500, default 50
- Award types may mix groups. When every one named is a contract or IDV, `assistance_listings` fails as `assistance_listings_type_mismatch`; when every one is assistance, `psc_codes` fails as `psc_codes_type_mismatch`. Code-filtered amounts cover whole matching awards, and DEF-filtered totals can be negative
- Rows carry `shape_code`, `display_name`, `aggregated_amount`, `population`, and `per_capita`, ranked by amount; `total_areas_available` counts every match before the cap
- `shape_codes` (1–500) returns only the listed areas, in the `shape_code` form of the layer: postal code for `state` (`NY`), 5-digit state + county FIPS for `county` (`36117`), 4-digit state FIPS + district for `district` (`3623`). Selection runs over every matched area, so it reaches areas ranked past `limit`; the codes are echoed as `applied_shape_codes`, and a code that matches no area is named in the `notice`
- With no filters, every award type is aggregated and `applied_award_type_default` says so; `subawards: true` switches to subaward data
---
### `usaspending_spending_by_category` <sub>tool</sub>
- `category` is `naics`, `psc`, `awarding_agency`, `awarding_subagency`, `funding_agency`, `funding_subagency`, `cfda`, or `recipient_duns`; takes the same `filters` object as `usaspending_spending_by_geography`; `limit` up to 100
- Rows carry `id`, `code`, `name`, and `amount`, ranked by obligation; `recipient_duns` rows carry the DUNS as `code` plus `recipient_id` and `uei` when upstream has them, and `recipient_id` chains to `usaspending_get_recipient`
---
### `usaspending_spending_over_time` <sub>tool</sub>
- `group` is `fiscal_year`, `quarter`, or `month` (fiscal month, where 1 is October); the same `filters` object, with `award_type_codes` defaulting to contracts, so `assistance_listings` needs an assistance group named; `subawards: true` switches to subaward data
- Rows carry `time_period`, `aggregated_amount`, and per-type `contracts`, `grants`, `direct_payments`, `idvs`, `loans`, and `other`
---
### `usaspending_disaster_spending` <sub>tool</sub>
- `dimension` is `overview`, `agency`, `cfda`, `recipient`, or `geography`; every dimension except `overview` requires `filters.def_codes` (e.g. `["L", "M", "N", "O", "P"]` for COVID-19); `limit` up to 100 on every dimension but `overview`; `spending_type` (`award`, the default, or `total`) applies to agency only, and geography takes `filters.geo_layer` (`state`, `county`)
- Rows carry `obligation`, `outlay`, and `award_count`, plus `total_budgetary_resources` on agency rows under `spending_type: total`; `overview` returns totals and `funding_by_def_code`. A recipient row's `id` chains to `usaspending_get_recipient`. The recipient total tops out at 10,000, and a response at that cap is flagged `truncated`. Geography areas are ranked by `aggregated_amount` and paged with `limit` and `page`, with the full area count as `total`; a page with areas below it is flagged `truncated`, and `truncationCeiling` is the lowest amount shown. Spending with no recorded place of performance ranks as one unattributed area
- Agency, cfda, and recipient also return `totals` across every matching row: `obligation`, `outlay`, and either `total_budgetary_resources` (agency, `total`) or `award_count`. When `overview` outlasts the request budget, the agency breakdown with `spending_type: total` still reports obligations, outlays, and budgetary resources
---
### `usaspending_search_federal_accounts` <sub>tool</sub>
- Optional `keyword` and 3-digit `agency_identifier`; `sort_field` is `account_name`, `account_number`, `budgetary_resources` (default), or `managing_agency`; `limit` up to 100
- Rows carry `account_number` (e.g. `097-8097`) for the federal-account tools, `managing_agency`, and `budgetary_resources`; `page_metadata.count` is the total
---
### `usaspending_get_federal_account` <sub>tool</sub>
- `account_code` in AGENCY-MAIN format, from `account_number` in search results or `federal_account` on an award; an unknown code fails as `account_not_found`
- Returns `total_obligated_amount`, `total_gross_outlay_amount`, and `total_budgetary_resources` for `fiscal_year`, plus `children`: one entry per Treasury Account Symbol with its own amounts
---
### `usaspending_get_federal_account_breakdown` <sub>tool</sub>
- `account_code` plus `dimension` (`program_activity` or `object_class`); `limit` up to 100, with `page_metadata.total` as the row count
- Rows carry `code`, `name`, and `obligations`; `program_activity` rows add `type`, either `PAC/PAN` or `PARK`
## Features
Built on [`@cyanheads/mcp-ts-core`](https://github.com/cyanheads/mcp-ts-core): stdio and Streamable HTTP transports, pluggable auth (`none` / `jwt` / `oauth`), swappable storage (`in-memory`, `filesystem`, `Supabase`, `Cloudflare KV/R2/D1`), structured logging with optional OpenTelemetry tracing.
USAspending-specific:
- USAspending.gov API v2, keyless: the data is public under the DATA Act
- Award search and the spending analytics tools cover action dates from 2007-10-01 on (an earlier start date fails as `date_before_earliest`), and DoD contract data lags publication by 90 days
- `usaspending_spending_by_category` puts eight category sub-routes behind one `category` enum, and `usaspending_disaster_spending` puts five disaster endpoints behind `dimension`
- Each request runs under one wall-clock budget (45 s by default); a slow answer gets the whole budget in one attempt, and only fast failures are retried. Failures surface as `api_timeout` or `api_unavailable` with each tool's recovery hint, and a rejected request carries USAspending's own explanation in the error message
Agent-friendly output:
- Chaining IDs as explicit fields: `generated_internal_id`, `agency_slug`, `recipient.recipient_id`, `federal_account`, and `account_number`, so agents follow the money without parsing display strings
- Honest pagination: `page_metadata.has_next` on every list, a `total` or `count` where the upstream publishes one, and `truncated` / `shown` / `cap` only when rows are known to exist beyond those returned. A full page with no such evidence keeps `has_next` without claiming truncation
- Empty results are notices, not errors: an empty page carries a `notice` echoing the filters and how to broaden them. The ID-keyed list tools (transactions, subawards, funding accounts, IDV children, account breakdown) return an empty list for an unknown ID rather than failing
- Typed failures with recovery hints: `award_not_found`, `recipient_not_found`, `agency_not_found`, `account_not_found`, `no_match`, `conflicting_input`, `date_before_earliest`, `date_range_inverted`, `unsupported_sort`, `assistance_listings_type_mismatch`, `psc_codes_type_mismatch`, `invalid_location`, `pagination_limit_exceeded`
## Getting started
### Public Hosted Instance
A public instance is available at `https://usaspending.caseyjhand.com/mcp` — no installation required. Point any MCP client at it via Streamable HTTP:
```json
{
"mcpServers": {
"usaspending-mcp-server": {
"type": "streamable-http",
"url": "https://usaspending.caseyjhand.com/mcp"
}
}
}
```
### Self-Hosted / Local
Add the following to your MCP client configuration file. No API key is required.
```json
{
"mcpServers": {
"usaspending-mcp-server": {
"type": "stdio",
"command": "bunx",
"args": ["@cyanheads/usaspending-mcp-server@latest"],
"env": {
"MCP_TRANSPORT_TYPE": "stdio",
"MCP_LOG_LEVEL": "info"
}
}
}
}
```
Or with npx (no Bun required):
```json
{
"mcpServers": {
"usaspending-mcp-server": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@cyanheads/usaspending-mcp-server@latest"],
"env": {
"MCP_TRANSPORT_TYPE": "stdio",
"MCP_LOG_LEVEL": "info"
}
}
}
}
```
Or with Docker:
```json
{
"mcpServers": {
"usaspending-mcp-server": {
"type": "stdio",
"command": "docker",
"args": [
"run", "-i", "--rm",
"-e", "MCP_TRANSPORT_TYPE=stdio",
"ghcr.io/cyanheads/usaspending-mcp-server:latest"
]
}
}
}
```
For Streamable HTTP, set the transport and start the server:
```sh
MCP_TRANSPORT_TYPE=http MCP_HTTP_PORT=3010 bun run start:http
# Server listens at http://localhost:3010/mcp
```
### Prerequisites
- [Bun v1.4.0](https://bun.sh/) or higher (or Node.js v24+).
- No API key or account: USAspending.gov is open to anonymous requests.
### Installation
1. **Clone the repository:**
```sh
git clone https://github.com/cyanheads/usaspending-mcp-server.git
```
2. **Navigate into the directory:**
```sh
cd usaspending-mcp-server
```
3. **Install dependencies:**
```sh
bun install
```
4. **Configure environment (optional):**
```sh
cp .env.example .env
# edit .env if you need to override defaults
```
## Configuration
No variable is required; the defaults work out of the box.

| `USASPENDING_BASE_URL` | USAspending.gov API v2 base URL. | `https://api.usaspending.gov/api/v2/` |
| `USASPENDING_TIMEOUT_MS` | Per-attempt HTTP timeout, in ms (1000–120000). Each attempt is cut at this or at the time left in the request budget, whichever is smaller; a timed-out attempt is not retried. | `45000` |
| `USASPENDING_RETRY_BUDGET_MS` | Wall-clock budget for one request, every attempt and backoff included, in ms (1000–300000). Fast failures such as a 503 retry inside it. | `45000`, or `USASPENDING_TIMEOUT_MS` when higher |
| `MCP_TRANSPORT_TYPE` | Transport: `stdio` or `http`. | `stdio` |
| `MCP_HTTP_PORT` | HTTP server port. | `3010` |
| `MCP_SESSION_MODE` | HTTP session mode: `stateless`, `stateful`, or `auto`. | `stateless` |
| `MCP_AUTH_MODE` | Authentication: `none`, `jwt`, or `oauth`. | `none` |
| `MCP_LOG_LEVEL` | Log level (`debug`, `info`, `warning`, `error`, etc.). | `info` |
| `LOG_TOOL_FAILURE_PAYLOADS` | Log each failed tool call's arguments and result, redacted by key name and capped at `LOG_TOOL_FAILURE_PAYLOAD_MAX_BYTES` (default `16384`). A secret inside a free-form value is not redacted. | `false` |
| `LOGS_DIR` | Directory for log files (Node.js only). | `<project-root>/logs` |
| `STORAGE_PROVIDER_TYPE` | Storage backend: `in-memory`, `filesystem`, `supabase`, `cloudflare-kv/r2/d1`. | `in-memory` |
| `OTEL_ENABLED` | Enable [OpenTelemetry](https://github.com/cyanheads/mcp-ts-core/tree/main/docs/telemetry). | `false` |
| `OTEL_EXPORTER_OTLP_LOGS_ENDPOINT` | Opt-in OTLP log export endpoint; the base `OTEL_EXPORTER_OTLP_ENDPOINT` never enables it. | — |
See [`.env.example`](./.env.example) for the full list of optional overrides.
## Running the server
### Local development
- **Build and run:**
```sh
# One-time build
bun run rebuild
# Run the built server
bun run start:stdio
# or
bun run start:http
```
- **Run checks and tests:**
```sh
bun run devcheck # Lint, format, typecheck, security
bun run test # Vitest test suite
bun run lint:mcp # Validate MCP definitions against spec
```
### Docker
```sh
docker build -t usaspending-mcp-server .
docker run --rm -p 3010:3010 usaspending-mcp-server
```
The Dockerfile defaults to HTTP transport, stateless session mode, and logs to `/var/log/usaspending-mcp-server`. OpenTelemetry peer dependencies are installed by default — build with `--build-arg OTEL_ENABLED=false` to omit them.
## Project structure
| Directory | Purpose |
|:---|:---|
| `src/index.ts` | `createApp()` entry point: registers the tools and initializes the USAspending service. |
| `src/config` | Server-specific environment variable parsing and validation with Zod. |
| `src/mcp-server/tools/definitions` | Tool definitions (`*.tool.ts`) plus shared filter, date, pagination, and formatting helpers. |
| `src/services/usaspending` | USAspending.gov API client: request timeouts, retry budget, raw response types. |
| `tests/` | Unit tests for tools, the service, config, and scripts. |
## Development guide
See [`CLAUDE.md`](./CLAUDE.md) for development guidelines and architectural rules. The short version:
- Handlers throw, framework catches — no `try/catch` in tool logic
- Use `ctx.log` for request-scoped logging, `ctx.state` for tenant-scoped storage
- Register new tools via the barrel in `src/mcp-server/tools/definitions/index.ts`
- Wrap external API calls: validate raw → normalize to domain type → return output schema; never fabricate missing fields
