What is the DOD Contracts (FPDS) MCP Server?
Connect your AI agent to the Federal Procurement Data System (FPDS) to monitor government spending and analyze contract awards in real-time.
What you can do
- Contract Search — Query the massive database of federal procurement actions using standard FPDS search syntax.
- DOD Targeting — Specifically isolate Department of Defense data by filtering for Department ID '9700' or Agency Code '9700'.
- Market Intelligence — Track vendor performance, identify upcoming procurement trends, and analyze historical spending patterns.
- Pagination Support — Navigate through large result sets using the start parameter to fetch data in batches of 10.
How it works
- Subscribe to this server
- Configure your access identifier
- Start querying federal contracts from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Government Contractors — monitor competitors and find new opportunities within the DOD.
- Data Analysts — extract raw XML contract data for spending analysis and reporting.
- Journalists & Researchers — track government transparency and public spending across federal agencies.
Built-in capabilities (1)
To target DOD contracts, include DEPARTMENT_ID:"9700" or AGENCY_CODE:"9700" in the sQuery parameter. Returns XML data containing contract entries. Search federal contracts via FPDS Atom Feed

Frequently asked questions
How do I specifically target Department of Defense (DOD) contracts?
To target DOD contracts, include DEPARTMENT_ID:"9700" or AGENCY_CODE:"9700" in your sQuery parameter when using the search_contracts tool.
Can I paginate through large sets of contract results?
Yes. The search_contracts tool supports a start parameter. Results are returned in batches of 10, so you can increment the start number (e.g., 10, 20, 30) to see more records.
What search syntax should I use for the sQuery parameter?
The search_contracts tool uses the standard FPDS Atom Feed search syntax. You can search by keywords, or use specific fields like VENDOR_NAME:"Example Corp" or PIID:"ContractID".
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
