Frequently asked questions
How do I find data for a specific local police department?
You can use the get_agency_summarized tool. You will need the agency's 9-character ORI (Originating Agency Identifier) to retrieve their specific reported statistics.
What kind of demographic information is available for crime victims?
The get_nibrs_victim_demographics tool allows you to filter victim data by age, race, or sex for specific offenses in states that support NIBRS reporting.
Can I compare crime trends over multiple years?
Yes. Tools like get_national_estimates and get_state_summarized accept start_year and end_year parameters to provide data across a historical range.
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.
