FAQ

Frequently asked questions

How do I check the municipality's income for a specific month?

Use the list_revenues tool with the ano (year) and mes (month) parameters. The agent will return the total income and breakdown for that period.

Yes, use the list_personnel tool. You can filter by year and month to retrieve data regarding public servants and their respective payroll information.

Is it possible to monitor active public tenders?

Absolutely. Use the list_bids tool to get a comprehensive list of all public tenders and bidding processes currently recorded in the portal.

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?
