FAQ

Frequently asked questions

Can I see the USD value of my tokens and NFTs?

Yes! Use the get_wallet_balances tool. It fetches native SOL, SPL tokens, and NFTs along with their current market pricing in USD.

How do I handle compressed NFTs (cNFTs)?

You can use get_asset to see details or get_asset_proof to retrieve the Merkle proof required for on-chain interactions with compressed assets.

Can I search for assets by specific creators or collections?

Absolutely. Use the search_assets tool with a JSON query to filter by collection ID, creator address, or specific attributes.

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.
