What is the USAspending (Federal Spending) MCP Server?
Connect to the official USAspending database and gain unprecedented transparency into how the United States government allocates its budget. This server allows any AI agent to query real-time federal financial data, from high-level agency overviews to specific contract details.
What you can do
- Agency Insights — Retrieve comprehensive overviews of toptier agencies, including their budgetary resources and obligations.
- Award Tracking — Search and filter through millions of federal awards, contracts, and grants using advanced criteria.
- Geographic Analysis — Break down spending by state, county, or congressional district to see where the money is going.
- Sub-Agency Breakdown — List specific offices and sub-agencies within a department to identify internal spending distribution.
- Historical Trends — Analyze spending and new award counts over time to identify fiscal patterns.
How it works
- Subscribe to this server
- Enter your USAspending API Key (if required for higher rate limits)
- Start auditing federal spending from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Policy Researchers — quickly gather data on agency obligations and budgetary resources for reports
- Journalists — track federal contracts and grants in specific regions or categories for investigative stories
- Data Analysts — export and analyze spending trends over time across different government sectors

Why CrewAI?
When paired with CrewAI, USAspending (Federal Spending) becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call USAspending (Federal Spending) tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Frequently asked questions
How do I get an overview of a specific agency's spending?
Use the get_agency_overview tool by providing the agency's toptier code. The agent will return high-level data including total obligations and budgetary resources.
Can I see which sub-agencies are spending the most within a department?
Yes! The get_agency_sub_agencies tool lists all sub-agencies and offices associated with a toptier agency, along with their respective obligated amounts.
Is it possible to filter federal awards by geographic location?
Absolutely. Use search_spending_by_geography to aggregate spending data by state, county, or district, or use search_spending_by_award with geographic filters.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
