Grove's MCP Server for Pocket Network

Instructions

Implementation Reference

• src/handlers/solana-handlers.ts:340-355 (handler)

  MCP tool handler logic in handleSolanaTool switch statement: extracts signature and network, delegates to SolanaService.getTransaction, returns JSON-formatted response or error.
  case 'get_solana_transaction': { const signature = args?.signature as string; const network = (args?.network as 'mainnet' | 'testnet') || 'mainnet'; const result = await solanaService.getTransaction(signature, network); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], isError: !result.success, }; }
• src/services/solana-service.ts:294-318 (helper)

  SolanaService.getTransaction method: retrieves Solana RPC service and calls 'getTransaction' RPC method with jsonParsed encoding and version 0 support.
  async getTransaction( signature: string, network: 'mainnet' | 'testnet' = 'mainnet' ): Promise<EndpointResponse> { const service = this.blockchainService.getServiceByBlockchain('solana', network); if (!service) { return { success: false, error: `Solana service not found for ${network}`, }; } return this.blockchainService.callRPCMethod( service.id, 'getTransaction', [ signature, { encoding: 'jsonParsed', maxSupportedTransactionVersion: 0, }, ] ); }
• src/handlers/solana-handlers.ts:118-136 (schema)

  Input schema definition for the tool, specifying required 'signature' parameter and optional 'network'.
  { name: 'get_solana_transaction', description: 'Get Solana transaction details by signature', inputSchema: { type: 'object', properties: { signature: { type: 'string', description: 'Transaction signature', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['signature'], }, },
• src/handlers/solana-handlers.ts:10-239 (registration)

  registerSolanaHandlers function that defines and returns the Tool[] array including get_solana_transaction for registration with MCP server.
  export function registerSolanaHandlers( server: Server, solanaService: SolanaService ): Tool[] { const tools: Tool[] = [ { name: 'get_solana_token_balance', description: 'Get SPL token balance(s) for a Solana wallet', inputSchema: { type: 'object', properties: { walletAddress: { type: 'string', description: 'Solana wallet address', }, mintAddress: { type: 'string', description: 'Optional: SPL token mint address (if not provided, returns all token balances)', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['walletAddress'], }, }, { name: 'get_solana_token_metadata', description: 'Get SPL token metadata (decimals, supply, authorities)', inputSchema: { type: 'object', properties: { mintAddress: { type: 'string', description: 'SPL token mint address', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['mintAddress'], }, }, { name: 'get_solana_balance', description: 'Get SOL balance for a Solana address', inputSchema: { type: 'object', properties: { address: { type: 'string', description: 'Solana address', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['address'], }, }, { name: 'get_solana_account_info', description: 'Get Solana account information', inputSchema: { type: 'object', properties: { address: { type: 'string', description: 'Solana address', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['address'], }, }, { name: 'get_solana_block', description: 'Get Solana block information with optional transactions', inputSchema: { type: 'object', properties: { slot: { type: 'number', description: 'Block slot number', }, includeTransactions: { type: 'boolean', description: 'Include full transaction details (default: false)', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['slot'], }, }, { name: 'get_solana_transaction', description: 'Get Solana transaction details by signature', inputSchema: { type: 'object', properties: { signature: { type: 'string', description: 'Transaction signature', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['signature'], }, }, { name: 'get_solana_prioritization_fees', description: 'Get recent prioritization fees for Solana transactions', inputSchema: { type: 'object', properties: { addresses: { type: 'array', items: { type: 'string' }, description: 'Optional: Account addresses to get fees for', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, }, }, { name: 'get_solana_block_height', description: 'Get the latest Solana block height', inputSchema: { type: 'object', properties: { network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, }, }, { name: 'get_solana_fee_for_message', description: 'Estimate fee for a serialized Solana message (base64)', inputSchema: { type: 'object', properties: { message: { type: 'string', description: 'Serialized message in base64', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['message'], }, }, { name: 'get_solana_program_accounts', description: 'Get accounts owned by a Solana program with optional filters', inputSchema: { type: 'object', properties: { programId: { type: 'string', description: 'Program ID (public key)', }, filters: { type: 'array', description: 'Optional RPC filters (memcmp, dataSize, etc.)', items: { type: 'object' }, }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['programId'], }, }, { name: 'get_solana_signatures', description: 'Get transaction signatures for a Solana address (transaction history)', inputSchema: { type: 'object', properties: { address: { type: 'string', description: 'Solana address', }, limit: { type: 'number', description: 'Maximum number of signatures to return (default: 10)', }, network: { type: 'string', enum: ['mainnet', 'testnet'], description: 'Network type (defaults to mainnet)', }, }, required: ['address'], }, }, ]; return tools; }
