Implementation Reference
- src/handlers/wallet.ts:193-204 (handler)The core handler function that implements the wallet_get_public_key tool. It retrieves the wallet instance using getWallet helper and returns the public key.
export const getPublicKeyHandler = async (input: any): Promise<ToolResultSchema> => { try { const wallet = await getWallet(input.wallet); return createSuccessResponse( `Wallet public key retrieved successfully: Public Key: ${wallet.publicKey} `); } catch (error) { return createErrorResponse(`Failed to get wallet public key: ${(error as Error).message}`); } }; - src/tools.ts:152-162 (schema)Input schema and tool metadata definition for wallet_get_public_key.

If not provided, uses PRIVATE_KEY environment variable if set." } }, required: [] } }, - src/tools.ts:556-608 (registration)Registration of tool names to their handler functions in the central handlers dictionary. Specifically maps 'wallet_get_public_key' to getPublicKeyHandler.
