# usaspending-gov-mcp

<!-- mcp-name: io.github.1102tools/usaspending-gov-mcp -->

MCP server for the USASpending.gov federal contract, award, subaward, recipient, agency, and federal account API.

No API key required. MCP is an open standard: this server runs in any MCP client, not just Claude. Executed and verified on eleven platforms in August 2026 (see [Configuration](#configuration)).

*Tested and hardened through ten rounds of integration testing against the live USASpending.gov API. 2,151 regression tests (1,783 offline, 368 live-gated); round 10 fixed 25 verified findings across both tool families, including filters that could never match and a tool that had never once succeeded. See [testing.md](testing.md) for the full testing record.*

## What it does

Exposes the USASpending.gov REST API as 55 MCP tools covering:

**Search and aggregation**
- `search_awards` - Primary search for contracts, IDVs, grants, loans, direct payments
- `get_award_count` - Dimensional counts across award categories
- `spending_over_time` - Time series aggregation (fiscal year, quarter, month)
- `spending_by_category` - Top N breakdowns by agency, vendor, NAICS, PSC, state, etc.
- `spending_by_transaction` - Modification-level transaction search
- `spending_by_geography` - State, county, or congressional district breakdown
- `new_awards_over_time` - Pipeline trend for a recipient

**Award detail**
- `get_award_detail` - Full record for a single award
- `get_transactions` - Full modification history for an award
- `get_award_funding` - File C funding data (Treasury account, object class, program activity)
- `get_award_funding_rollup` - Single-line funding summary
- `get_award_subaward_count`, `get_award_federal_account_count`, `get_award_transaction_count`
- `get_idv_children` - Task/delivery orders under an IDV
- `awards_last_updated` - Data freshness check

**Subawards (FFATA)**
- `search_subawards` - Subawards under a single prime
- `spending_by_subaward_grouped` - Subaward search with full filter set

**Recipients**
- `search_recipients` - Search recipients by keyword
- `get_recipient_profile` - Full recipient record
- `get_recipient_children` - Subsidiaries of a parent recipient
- `autocomplete_recipient` - Find recipient hashes by partial name
- `list_states` - All states with FIPS codes

**Agency depth**
- `list_toptier_agencies`, `get_agency_overview`, `get_agency_awards`
- `get_agency_budgetary_resources` - Budget resources by FY
- `get_agency_sub_agencies` - Subordinate orgs with obligations
- `get_agency_federal_accounts` - Funding sources (TAS)
- `get_agency_object_classes` - Spending categories (OMB)
- `get_agency_program_activities` - Program-level breakdown
- `get_agency_obligations_by_award_category` - Contract vs grant mix

**IDV depth**
- `get_idv_amounts` - Top-line IDV rollup
- `get_idv_funding`, `get_idv_funding_rollup` - File C for IDV
- `get_idv_activity` - Child orders under an IDV

**Federal accounts (Treasury)**
- `list_federal_accounts` - Search TAS
- `get_federal_account_detail`, `get_federal_account_object_classes`,
  `get_federal_account_program_activities`, `get_federal_account_fy_snapshot`

**Autocomplete**
- `autocomplete_psc`, `autocomplete_naics`
- `autocomplete_awarding_agency`, `autocomplete_funding_agency`
- `autocomplete_cfda` (grants), `autocomplete_glossary`, `autocomplete_recipient`

**Reference data**
- `get_naics_details`, `get_psc_filter_tree`
- `get_award_types_reference` - All award type codes (A=BPA Call etc.)
- `get_def_codes_reference` - Disaster Emergency Fund codes (COVID, IIJA, IRA)
- `get_glossary` - Acquisition/spending vocabulary
- `get_submission_periods` - Agency reporting period coverage
- `get_state_profile` - State-level spending profile

**Workflow convenience**
- `lookup_piid` - Auto-detects contract vs IDV and returns the matching award

## Installation

### Via pip

```bash
pip install usaspending-gov-mcp
```

### Via uvx (recommended, no venv needed)

```bash
uvx --from usaspending-gov-mcp usaspending-mcp
```

The `--from` is required for this server and only this server. The PyPI package
is `usaspending-gov-mcp` but the console script it installs is `usaspending-mcp`,
so a bare `uvx usaspending-gov-mcp` fails with "An executable named
usaspending-gov-mcp is not provided by package usaspending-gov-mcp".

Do **not** run `uvx usaspending-mcp` either. `usaspending-mcp` is an unrelated
third-party package on PyPI, not this project.

### From source

```bash
git clone https://github.com/1102tools-dev/federal-contracting-mcps.git
cd federal-contracting-mcps/servers/usaspending-gov-mcp
pip install -e .
```

## Configuration

MCP is an open standard, and this config was executed and verified in August 2026 on eleven platforms: Claude Desktop, Claude Code, Codex Desktop and CLI, Gemini via Antigravity, GitHub Copilot CLI, DeepSeek Harness, Grok Build, Cursor, opencode, and LibreChat. Most clients take the same JSON block below and differ only in where the config file lives; the [universal setup guide (PDF)](https://1102tools.com/downloads/1102tools-universal-setup.pdf) has the exact file path and format for every platform, including the Codex TOML form.

```json
{
  "mcpServers": {
    "usaspending": {
      "command": "uvx",
      "args": ["--refresh-package", "usaspending-gov-mcp", "--from", "usaspending-gov-mcp", "usaspending-mcp"]
    }
  }
}
```

The `--refresh-package` flag tells uv to check PyPI for a newer release each time your client launches the server, so fixes arrive automatically; without it, uv keeps serving whatever version it first cached. It adds a moment of network time at startup, so raise your platform's MCP startup timeout if it enforces a short one.

If you installed via `pip install -e .` or a regular `pip install`:

```json
{
  "mcpServers": {
    "usaspending": {
      "command": "python",
      "args": ["-m", "usaspending_gov_mcp.server"]
    }
  }
}
```

Restart the client and the tools appear.

## Example prompts

Once configured, try:

- "Show me the top 10 NAVSEA contracts awarded in FY2025 by dollar value."
- "Find all software development contracts at NASA with sole-source justifications in the last year."
- "How much has Leidos received in federal awards since 2020? Group by fiscal year."
- "What are the top 15 recipients of HUBZone set-aside contracts at DoD?"
- "Pull the full modification history for PIID N00024-24-C-0085."
- "Compare FFP vs T&M award counts for IT services at Air Force in FY2024."

## Design notes

- **No authentication required.** USASpending.gov is a free, public API.
- **Award type groups cannot be mixed.** The `award_type` parameter takes one of: `contracts`, `idvs`, `grants`, `loans`, `direct_payments`, `other`. Use separate calls for separate categories.
- **Actionable error messages.** Common API errors (422 mixed award types, 400 sort field missing, 400 empty keywords) are translated into guidance for the calling LLM.
- **Sort field auto-handling.** The USASpending API requires the sort field to appear in the fields array; this server adds it automatically.
- **Sensible defaults.** Search limits default to 25 (API max 100). Default fields cover the most common columns for each award category.
- **Flat filter parameters.** Most common filters are surfaced as named parameters (`keywords`, `awarding_agency`, `naics_codes`, etc.) rather than a nested filter dict, for better LLM tool discovery.

## Data source

All data is sourced from [USASpending.gov](https://www.usaspending.gov), which aggregates FPDS-NG contract data, FAADC assistance data, and agency DATA Act submissions. Data freshness varies by agency: non-DoD contract data is typically available within 5 business days, DoD and USACE procurement data has a 90-day reporting delay in FPDS, and financial assistance data is available within 2 days of submission.

## Request pacing

Every upstream request uses a provisional 3-second cross-process anti-burst
interval by default. USASpending does not publish a numeric limit, so this is
a 1102tools safeguard rather than a provider requirement. Override with
`FEDERAL_API_MIN_INTERVAL_SECONDS`, use `0` to deliberately disable it, and
use `FEDERAL_API_PACING_DIR` to relocate local pacing state.
