Perplexity

Claude Desktop MCP Server Integration

`get_asset` and `get_assets_by_owner` pull exact token metadata into your Claude workspace. You ask your AI client for a specific wallet portfolio, and it grabs the live on-chain balances without requiring you to open an explorer tab. The `get_priority_fee_estimate` endpoint grabs current network conditions before you execute a trade. Claude reads the serialized transaction and suggests the exact micro-lamport fee required to land it on the next block.

Parse Raw Transactions Instantly

`parse_transactions` turns unreadable Solana instruction data into plain English. You paste a transaction signature into the chat, and the agent breaks down exactly which tokens moved and who paid the fees. Pairing this with `get_transaction_history` gives you a complete audit trail for any address. Your agent pulls the historical data, parses the raw logs, and builds a chronological timeline of a user's on-chain activity right in your chat window.

Track Wallet Funding Sources

`get_wallet_funded_by` identifies the exact exchange or address that seeded a new Solana account. You drop a suspicious address into Claude, and it immediately traces the initial SOL deposit back to its origin. Once you know the source, `get_wallet_identity` resolves associated .sol domains. The AI client cross-references the address against known entities, giving you a human-readable name instead of a random string of characters.

Common questions about Helius (Solana) MCP in Claude Desktop

Open your `claude_desktop_config.json` file from the developer settings. Add the server command and arguments under the `mcpServers` key, then restart the application.

Yes. The `get_asset_proof` tool specifically fetches the Merkle proofs required for compressed assets. Your agent can read this data to verify ownership off-chain.

You likely asked for an estimate without providing a serialized transaction. The `get_priority_fee_estimate` tool needs the exact transaction payload to calculate accurate compute unit pricing.

The endpoints query whatever network your API key is configured to target. Pass the correct RPC URL to the tools to switch environments.

Your on-chain transaction histories and public wallet balances route locally through the stdio transport. Vinkius isolates the execution environment, meaning your queries never touch external logging servers outside the direct API request.
