What is the Helius (Solana) MCP Server?
Connect your Helius account to any AI agent to interact with the Solana blockchain with unprecedented speed and depth. This server leverages Helius's powerful RPC and DAS (Digital Asset Standard) API to provide real-time blockchain intelligence.
What you can do
- Asset Management — Fetch detailed metadata for NFTs, cNFTs, and fungible tokens using
get_assetorget_asset_batch. - Wallet Intelligence — Retrieve complete balances with real-time USD pricing using
get_wallet_balancesand track history withget_wallet_history. - Ownership Tracking — List every asset owned by a specific Solana address via
get_assets_by_owner. - Network Optimization — Get precise priority fee estimates with
get_priority_fee_estimateto ensure your transactions land during high congestion. - Advanced Search — Query the blockchain for specific assets based on collection, creator, or attributes using
search_assets.
How it works
- Subscribe to this server
- Enter your Helius API Key
- Start querying Solana data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Web3 Developers — Debug smart contracts and verify on-chain state without leaving your IDE.
- Crypto Analysts — Perform deep wallet forensics and portfolio tracking through natural language.
- NFT Collectors — Manage and inspect compressed NFTs and collections with ease.

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 Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Helius (Solana) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
