FAQ

Frequently asked questions

How can I check if any of my indexers are currently down?

You can use the get_indexer_status tool. It retrieves the current health status of all configured indexers, highlighting any errors or connection issues.

What is the best way to add a new indexer without knowing the JSON structure?

First, run get_indexer_schema to see the templates for supported indexers. Once you have the correct fields, you can use add_indexer with the required data.

Can I verify my settings before applying them to an indexer?

Yes! Use the test_indexer tool. It allows you to test the connection and configuration of an indexer before saving it, preventing broken setups.

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.
